10 Best Laptop Diagnostic Software Tools PC Health Check

Diagnostic programs allow you to determine the state of the computer as a whole and its individual components. It can use them for performance verification, temperature control, or continuous system monitoring. Should be installed At least one utility on any laptop because the use of diagnostic programs allows you to detect problems in time and eliminate their cause.


CPU-Z is one of the most famous programs for diagnosing PCs and laptops. It is available for free download; it offers the most simple interface – one window, divided into several tabs with information about devices.

CPU-Z shows detailed information about the processor

CPU-Z stands out among diagnostic utilities for its depth of analysis. This is especially true for checking the processor. After a short scan, the program will show its type, process technology, core voltage, heat dissipation indicators. Information of similar depth is available for the RAM and the motherboard chipset. This makes the program indispensable for overclocking enthusiasts.

CPU-Z also allows CPU benchmarks to check performance and stability under load. Test reports are saved in TXT and HTML documents. To test the processor:

  1. Go to the Bench tab.
  2. We select the mode of checking one core or several.
  3. In the Reference drop-down list, select the reference processor with which we want to compare our chip.
  4. Click Bench CPU to run the test.

We compare the processor with the reference to assess its performance

The program interface will immediately display the results obtained – how much is your processor better or worse than the selected standard. A stress test can be done similarly. The main thing is to monitor the processor’s temperature – this will require other diagnostic programs, which we will talk about below. See also: how to find out CPU temperature in Windows 10.


Supports all Windows versions.
Gives the maximum amount of information about the processor, motherboard, RAM.
It does not take up much space; it is undemanding to resources.
Allows simple performance tests.


Doesn’t show hard disk information.
Provides little information about the video card – only the manufacturer, model, and type of memory.
Does not monitor the temperature of individual components.


The program GPU-Z eliminates the CPU-Z disadvantages and provides very detailed information about the video card. The utility shows all the parameters of the graphics adapter up to the device code. Information about cores, memory, power subsystems, frequency, the temperature of the video card – everything is collected in a single GPU-Z interface. An interesting feature of the program is the detection of fake video cards. If the actual parameters do not correspond to the technical characteristics of the model, then the Fake message will appear in the information about the device, and an exclamation mark will be displayed instead of the manufacturer’s logo.

GPU-Z knows all about the graphics adapter

In the program’s parameters, you can configure it to start automatically with the system and minimize to the tray with a demonstration of the selected value – for example, the temperature of the video card. A convenient option is placing the utility on top of all windows. You will definitely appreciate this opportunity if you will overclock or test a video card and need constant monitoring of its condition.

Speccy is a free program from Piriform, the developer of the popular CCleaner system cleaning utility. The application performs laptop diagnostics at startup, after which it displays basic information about important components: motherboard, processor, video card, hard disk, RAM. For convenience, the most important data is collected on the General Information screen. There are links to sections of individual devices in the left pane – there is much more information in them. For example, in the submenu “Data storage,” you will find the result of the SMART analysis of the hard disk, which shows its current state.

Speccy contains detailed characteristics of devices and their current status

During monitoring, the temperature of each device is measured. Speccy warns the user about exceeding the permissible heating values ​​by repainting the icon in a threatening red color. You can also enable the display of the temperature of an individual device in the system tray.

  • Expand the “View” menu and go to “Options.”
  • On the “Notification area” tab, mark the minimization to the tray and display values, and then select the device and sensor – for example, the motherboard’s temperature.

You can configure the automatic inclusion of Speccy at system startup if you want to monitor the status of the laptop constantly.

System Explorer

System Explorer is a complete replacement for the standard Windows Task Manager, which offers significantly more information about the processes and provides additional tools for monitoring the system’s state. The program is available for free download and does not take up much disk space.

System Explorer’s default interface is similar to Task Manager. It is a window with four tabs showing current processes, performance, connections, and the history of various actions. If you need more information, we recommend switching to Explorer Mode. The data is presented in the form of an “Explorer,” which is navigated through the side menu.

System Explorer replaces several system utilities at once

Through System Explorer, you can:

Monitor system performance.
View current tasks and create new ones.
Monitor and manage the performance impact of processes.
Examine running modules, services, drivers used.
Customize the startup list.
Monitor the parameters of the antivirus and Windows Firewall.
Take snapshots of the system and compare them with each other.

System Explorer checks running processes through its own database and warns about the presence of malicious files. To do this, the program requires an internet connection.


Offers in a single interface the functionality of several system utilities with advanced capabilities.
Monitors the performance of the system in real-time and displays indicators through the icon in the system tray.
Provides detailed information about all actions in the system: starting files and programs, shutting down applications, connecting to the network, etc.


A large number of settings can be confusing.
No built-in tests and no information about connected devices.
The program is rarely updated.


AIDA64 is a powerful application for diagnosing and monitoring system health. The program selects information from the BIOS memory, tells about all connected devices, and provides links to additional information. In addition, AIDA64 provides users with performance and stability testing tools under load. The only problem is that all of this is available for free only for a 30-day trial period. License cost – $ 40.

AIDA64 allows you to test devices

In the “Test” section, you can run a test of individual parameters of the RAM, processor, and other components. For example, if we want to know the performance of the CPU and compare it with those of other chips, then we do the following:

  • First, go to the “Test” section.
  • We select the parameter that we want to check.
  • We press “Start.”

The test results will be sorted in a comparison table with other processors. The main characteristics of the device will also be indicated there. Separate tests allow you to check the performance of drives, find out the bandwidth of the cache and RAM, diagnose the monitor and assess the general state of the system when operating under load.


The maximum possible list of device characteristics, including links to detailed descriptions on specialized sites.
Comparison with other systems when conducting tests.
Taking readings from all sensors of the laptop.
A large number of built-in tests for different devices up to the monitor.


You can only use it for free for 30 days.


The program HWMonitor is developed by the same company as the CPU-Z. However, unlike that diagnostic utility, the emphasis here is on real-time status checking rather than showing detailed information about specifications and firmware. The program interface is a single table that lists all installed devices. For each component, a check of voltage, frequency, temperature, percentage of utilization, amount of occupied memory is available. The existing data can be saved in a TXT file.

HWMonitor displays a large table with detailed characteristics

HWMonitor also has a paid Pro version. It offers several additional functions, including remote control of the laptop’s status through another computer or phone and displaying the temperature of the selected component in the system tray when minimizing the main program window.

HWiNFO is a small utility that shows the main characteristics of a laptop and its components. Knows how to take readings from sensors, which allows you to monitor the temperature of the components and voltage through it. The program is distributed under a free license, but as gratitude, the developer can send him any amount.

HWiNFO takes accurate readings from all sensors that the laptop has

One of the main advantages of HWiNFO is its low resource requirements. The program runs differently even on older Windows XP machines, not to mention modern laptops with the latest OS versions. All devices available for diagnostics are presented in a single menu. By switching between tabs, we learn detailed information about each component of the laptop. Additional features of the program include updating the BIOS of the motherboard and device drivers. However, use these features with care. It is much safer to update BIOS and device drivers manually rather than using a generic algorithm.


Detailed reports on the characteristics and current condition of the equipment.
Taking high-precision readings from different sensors.
Tools for updating BIOS and device drivers.


There are no benchmarks to check performance and stability under load.


SpeedFan is a simple utility for monitoring the main indicators of a laptop. Shows CPU frequency, fan speed, voltage, the temperature of other devices. This program is also loved by users who are engaged in overclocking PCs and laptops, as it provides accurate information about the current state of important components. Separate information is collected in graphs that are easy to visualize.

SpeedFan program knows everything about coolers

The SpeedFan program allows you to change the speed of the coolers. This can be useful if the laptop is overheating and we want to pump up the cooling system a little.

  1. Click on the Configure button.
  2. Go to the Advanced section.
  3. Find the Pwm Mode elements in the list and make sure that they have the Manual status. If another mode is selected, select each element and select the Manual status through the Set To line.

    You can change the rotation speed manually

  4.  We return to the main window of the program.
  5. Use the arrow buttons to change the value of the Pwm1 parameter.
  6. We check how the fan is working – see if the temperature of the processor or other component has dropped.

Experimentally, you can determine which fan blows a particular device (if several coolers are installed), and then rename the parameters in the program interface.


Allows you to control the speed of the fans.
Performs a SMART test on its own, monitoring the condition of the hard drive.
Monitors the voltage at the terminals of the power supply.
Checks the temperature of critical components: processor, video card, memory.


There is no detailed information about the components of the computer, only the current indicators of their work.
There are no built-in tests.


PCMark is a program for testing system performance. Futuremark developed it. They also have a utility called 3DMark, which is also designed to conduct stability and performance tests and check the processor and video card bundles. PCMark covers more subsystems.

PCMark offers various benchmarks for system performance and stability

With the help of this program, we can determine the capabilities of a laptop for rendering and editing video, complex calculations, storage, and transmission of data. Various tests help determine the speed of writing and reading of RAM and permanent memory, the power of each processor core, the speed of rendering graphics card objects. The utility includes some 3DMark test tools to determine the laptop’s suitability for high-load games.

After the test, the result appears on the screen in points. The rating allows you to judge the performance of a laptop. The tester also reports on what problems were found during the test and advises on upgrading your computer.


Conducts general laptop performance testing.
Analyzes the state of the OS.
Compares the results with the ratings of other users.


In the basic version, the interface is not translated into Russian.
The program has a paid version in which all testing tools are available. But for a basic check and determination of the weak points of the laptop, the capabilities of the free edition of the utility are enough.


FurMark is the benchmark for verifying the performance of discrete graphics cards and embedded video systems. Basically, it is a set of stress tests that test the graphics subsystem for stability under load. The utility is distributed under a free license and receives regular updates.

All graphics card resources are required to render this render.

FurMark’s interface consists of a test setup window and a section for conducting it, in which a complex render rotates. Before starting the test, we select the graphics level and test mode. For example, you can enable full-screen mode, select a resolution, adjust anti-aliasing. A significant point is the indication of the duration of the check. Prolonged exposure to load can damage the video card.

After starting the stress test, a render appears on the screen, drawing all the resources of the graphics adapter. It is not recommended to use other applications on the laptop. The only program that needs to be running is a temperature monitoring diagnostic utility such as GPU-Z. Depending on the set parameters, testing stops after the selected time or manually.


The most rigorous and honest check of a video card for performance, stability, and power consumption.
Different testing modes.
Possibility of automatic and manual completion of the check.
Together with the utility, GPU-Z is installed – a program for diagnosing a video card.


The interface is not translated into Russian.
Graphics adapter load limit.
FurMark can literally burn your graphics card and other components. Therefore, before starting it, you need to make sure that the cooling system on the laptop is working correctly. The first test is recommended to be carried out no more than 5 minutes, constantly monitoring the temperature of the graphics adapter and other devices.


It all depends on the task at hand. If the goal is simply to monitor all system indicators and the laptop’s state, you can get by with utilities such as Speccy, HWinfo, HWMonitor, System Explorer. They do not have testing tools, but they have a lot of useful information that allows you to detect weaknesses and prevent errors.

Overclocking users need CPU-Z, GPU-Z, AIDA64, SpeedFan, PCMark, and FurMark. They may contain slightly less information about the characteristics of the device and the state of the system. Still, there are powerful tests to check the performance and stability of the laptop under load.


How to Choose a Good Gaming Monitor

Comfort in the game depends on a comfortable chair and table, the computer’s performance, and the monitor. The quality of the displayed image depends on the settings of the monitor and its refresh rate, color reproduction, and many other characteristics.

Which PC Gaming Monitor Should You Choose? What to remember and what to pay attention to?

The jungle of screens does not choose a gaming screen. We go through the most important things you need to keep in mind if you get a new gaming screen.

Buying a monitor can easily be equated with buying any component for your computer – we mean it’s a mistake. This is probably the most important purchase you can make in terms of hardware. It’s not just about getting a good picture; it’s basically about what gaming experience you want.

This article provides answers to what to look for and what you can more or less ignore.

Gaming Monitor – Matrix Types

One of the first questions to look out for when thinking about which gaming monitor to choose is the matrix type. The basic parameters of the display will depend on the decision made.

It determines the picture quality, color rendition, viewing angles, and so on. This is the main component of the device, its “filling.” Therefore, it is also worth paying attention to when buying a new monitor.

There are different types of matrix. The most common matrix are of four types:

  • TN – the “fastest” matrix but with viewing angles and color reproduction, they are not very good;
  • IPS – lead in picture quality, but only madly expensive models can match TN in speed;
  • VA – they have excellent speed and decent color reproduction, at the IPS level in the same price category. In addition, VA matrices usually have twice or even three times higher static contrast ratio and more uniform backlighting.
  • OLED – OLED screens stand out thanks to their incredible brightness and contrast ratios. It is enough to look at a barely luminous diode to see a significant difference compared to LED matrices.

They are widely used in modern gaming monitors, including the MPG and MAG series from MSI, on the example of which we analyze the topic of this material. VA matrices are in demand due to excellent contrast, good color rendering, and wide viewing angles. This is the best thing you can buy for gaming.

TN matrix for a gaming monitor

TN is a popular solution that can find in both budget monitors and more expensive models. TN panels are cheaper to manufacture but also have their drawbacks. The main advantages and disadvantages of TN-matrix in gaming monitors are presented below.

Advantages of TN matrices:

  • Low price You can buy a gaming monitor with a TN matrix of up to 150 USD.
  • Speedy response times, minimal delays.
  • High refresh rate even on cheap monitors.

Disadvantages of TN matrices:

  • Poor color rendering than monitors with VA or IPS matrices.
  • Narrow viewing angles.
  • Problems displaying deep blacks.

IPS matrix in a gaming monitor

An IPS gaming monitor is a popular choice, especially among gamers on a slightly larger budget who appreciate better color reproduction and wide viewing angles. IPS matrices are more expensive, but they make up for the price with image quality. Their most significant advantages and disadvantages are presented below.

Advantages of IPS matrices:

  • Good color rendering.
  • Wide viewing angles.
  • Deep blacks and optimal contrast.

Disadvantages of IPS matrices:

  • Higher purchase price than TN matrix.
  • The response time is worse than for TN or VA matrix.

VA matrix in a gaming monitor

VA matrices in gaming monitors are a solution that can be viewed as a kind of compromise that combines the key advantages of TN and IPS matrices. The offer of gaming monitors with such a matrix is ​​expanding, and its advantages and disadvantages are presented below.

Advantages of VA matrices:

  • Reasonable price – VA matrix is ​​more expensive than TN but cheaper than IPS.
  • Good color rendering.
  • Proper viewing angles – definitely wider than with TN.

Disadvantages of VA matrices:

  • Response time – slower than TN but faster than IPS.

OLED matrix in a gaming monitor

OLED matrices in gaming monitors stands for Organic-Light-Emitting-Diodes. The essence of the technology is that each pixel of the display is a separate light source. A large pixel size allows for much higher resolution, pixel density, and therefore image quality. Rich colors and energy-saving: the advantages of OLED Perfect black Each pixel emits light by itself, so when you turn off one or a group of pixels.

Advantages of OLED matrices:

  • In terms of brightness and color, each pixel works entirely independently of all the others. This helps to display all colors correctly in every area of ​​the image.
  • Viewing angles . The image is clearly visible from a wide variety of viewing angles without loss of quality.
  • Flexibility . OLED matrices can be of almost any shape and design. Due to their extreme flexibility, such displays can be rounded as desired.

Disadvantages of OLED matrices:

  • High price . At the moment, all OLED TVs are very expensive. They have completely occupied the premium class, which many potential buyers cannot afford.
  • OLED displays are pixel burnout (especially blue color), which, in turn, leads to color distortion and loss of contrast. This reduces the lifespan of the TV.

After examining the types of matrices available, a decision needs to be made. It is best to do so based on the types of games you play most often and considering whether the monitor is mainly used for games or perhaps also for work or other applications.

Gaming monitor – which matrix for which games

If one type of matrix met the expectations of all buyers, there would be no point in producing other types of monitors. However, since each type of matrix has its advantages, it is worth considering which solution is best for a particular kind of game.

Buyers most often choose between a TN or IPS monitor, but it is also worth remembering the VA matrix, and, in addition, the type of matrix itself should be adapted to the specifics of the games used.

  • A monitor for dynamic gaming – like action games, FPS, or FPP – can have a TN matrix, providing the fastest response times and possibly the best refresh rate compared to other monitors for the same price.
  • A monitor for RPG, adventure, and strategy games – response time is not as important as perfect color reproduction, deep blacks, and effective contrasts, so an IPS monitor is the best choice.

You can find an IPS monitor with good response times and high refresh rates for higher purchasing budgets.

Players who play games of all kinds and users looking to buy a monitor for gaming and work can also opt for a VA monitor that combines the features of IPS and TN monitors in terms of both quality and price.

What size gaming monitor to choose

No less important than the type of matrix and the resolution of the monitor is its size. This decision should be made based on the available space for the monitor – a small corner table is not suitable for a widescreen monitor with a large diagonal, and a small screen would be a poor choice for a large and spacious table.

What monitor size should I choose? Here are the most popular sized monitors:

  • 24 inches is a popular and very versatile gaming monitor size for work and many other applications. It fits easily on any desk. A monitor of this size performs well at Full HD resolution.
  • 27 inches – A slightly larger screen will provide a better experience when playing games or watching movies. A 27-inch or 28-inch gaming monitor usually has the most common aspect ratio (16: 9) and performs well with Full HD and WQHD resolutions.
  • 34 “and above – Monitors with a screen size of 34″ and up will work great on a large desk. It’s a good choice when looking for a widescreen monitor or curved screen (usually large). Monitors of this size can be bought in various resolutions, but the most prominent gaming monitor will benefit from a 4K resolution.

The largest gaming monitors can be 65, 86, or even 98 inches – but these are expensive and very large solutions for a standard desktop. However, if you prefer to play on the big screen, it is worth considering TV.

Gaming Monitor – What Resolution

Another essential issue to consider when choosing a gaming monitor is monitor resolution. This question should be made dependent on the available budget and the parameters of the computer itself.

The most popular solutions today include:

  • Full HD resolution is still hugely popular, although we will find a huge range of higher-resolution monitors on the market. The advantage of a Full HD monitor will be a lower price point over a WQHD or 4K monitor and that it will work well even with weaker graphics cards.
  • WQHD resolution is a resolution that provides higher picture details than Full HD. WQHD gaming monitors are also not as expensive as 4K models, and we can easily buy a model with that resolution with a high refresh rate.
  • 4K is the most expensive solution and offers 60Hz refresh, which is a big drawback for fast-paced action games. This resolution is recommended for monitors with a large diagonal screen and for computers with a good video card. A 4K gaming monitor is a good choice when shopping for a monitor for games and movies.

The screen resolution directly affects the image detail. Still, the most advanced solution will not always be the best – a lot depends on the tools available (it’s hard to find a 4K gaming monitor for under 20,000 rubles).

Curved screen – yes or no?

Now that we have analyzed the leading technical indicators, it is worth talking about the design features. For example, is it worth looking into curved screens? Many companies have been selling such monitors in stores for about five years.

Why is it getting popular? There are two reasons at once. Firstly, the curved screen gives the picture some volume. This is because the image surrounds the person and creates the effect of depth.

It looks especially great in games with a first-person camera, because in reality, what we see is also around us and not on a flat “canvas.” 

Secondly, the curved screen design allows for an even wider viewing angle when assembling multi-monitor configurations. By putting three monitors together, you can get a panorama with a 180-degree field of view with little or no gaps. Ordinary flat screens can be arranged in a “three,” but in this case, they are located at an angle, which disturbs the perception of the game.

Even though ordinary gamers still rarely use multiple monitors at once, the curved screen is an excellent feature that positively affects the immersion in the game. So our answer is yes. And if you still want to try a bunch of three monitors, then look for frameless ones.

As an example, a multi-monitor configuration of the 27-inch MSI Optix series with a refresh rate of 144 Hz. Among other things, this model boasts the use of Anti-Flicker and Less Blue Light technologies, which do an excellent job with screen flicker and reduce the intensity of blue light.

Gaming monitor Response time

It’s about how quickly the screen’s pixels change from, for example, entirely off to entirely on or how fast they change in grayscale – this partly affects lag in the image. But since there is no uniform standard and it is a single figure taken from a complex context, it is time to bury that specification once and for all.

How is this parameter measured, and what should you know about monitor response time?

Refreshing the image in gaming monitors is one of the most important parameters, especially for a monitor for dynamic action, FPS, and FPP. Higher refresh rates combined with slower response times will provide the smoothest image display.

Higher hertz is always right – to a specific limit.

Some myths surround the frequency of updates. Sometimes, it is not possible to prove that high refresh rates make you a better gamer (almost true). At the same time, few computers can render as many frames per second (FPS) as the screens can display.

But it is precisely at the collapse of these two that a high refresh rate comes into the picture. The higher the hertz, the lower the latency. The lower the latency, the more flow in the image, regardless of whether you are swinging between high-rise buildings located at 250 km / h just outside Edinburgh or have your best friend insight for an approaching gib.

FPS vs. Hz

We take it from the beginning. FPS? Hertz? FPS stands for Frames Per Second. This is how many frames the computer can render and send to the screen. It depends on how high quality you have on the graphics and what resolution you set.

Hertz (Hz), in turn, stands for “events per second” in this case, how many times the screen updates the image per second. So we want the computer to pump out many frames per second, and we then want the screen to be able to display at least as many or more.

  • 60Hz is the frequency used in the cheapest monitors, but also 4K models. It is worth remembering that the effect of the final refresh rate also depends on the cable (interface) used and the screen resolution. The 60Hz refresh is also recommended for work for strategy and RPG games, not fast-paced shooters.
  • 75Hz is a compromise solution for buyers interested in various games but on a small budget. You can buy a 75Hz refresh monitor for a little over £ 1,000.
  • 144 Hz – Recommended refresh rate for players who prefer online battles and fast-paced games. A 144Hz gaming monitor performs well in day-to-day use, but keep in mind that this refresh rate is used primarily by Full HD and WQHD monitors and only a few higher resolution models.
  • 240 Hz is an extremely high refresh rate that is practically only used in Full HD monitors. This type of monitor can be recommended for fast-paced online gaming, especially when they opt for a TN matrix monitor and fast response times.

Gaming Monitor – What’s the Input Lag

Refresh rate and response time are not the only factors affecting the smoothness of the displayed image. An equally important issue is signal latency, that is, input latency. This parameter is specified in units of ms (similar to monitor response time) if manufacturers provide this information at all.

Since input lag is not a fixed element of a monitor’s specifications, many manufacturers overlook this issue before buying a monitor; it is worth looking for monitor tests done in this regard – the lower the input lag, the better.

We can assume that in good gaming monitors, input lag should not exceed 11ms.

FreeSync andG-SYNC

Technologies created in the depths of NVIDIA and AMD change the refresh rate depending on the speed of frame rendering. Visually, we get a smoother picture without image tearing at a rendering speed of 30-60 frames per second or lower. To work, you need an appropriate video card from the manufacturer.

The industry has developed a flexible standard that allows the screen to adapt to the number of frames that the computer produces. It’s called VESA Adaptive Sync. However, you may have heard of it with two other slightly nicer names – AMD Freesync and Nvidia G-Sync respectively.

This technology is built into basically all modern screens, and if one is supported, it will also be supported by the other. The name is set depending on which graphics card you have—Freesync for AMD and G-Sync for Nvidia’s graphics cards. In general, it can be said that AMD graphics cards from 2014 onwards can be expected to support it and all Nvidia cards from the 10, 16, 20, and 30 series.

However, it would help if you connected the monitor via DisplayPort cable. This particular technology does not work with HDMI.

Connection interfaces

Gaming monitors in 2019 are equipped with HDMI and DisplayPort. The former has a 144Hz refresh rate limit, while the latter allows you to squeeze the most out of your system.

Typically, gaming monitors over 144 Hz are a theoretically equipped with DisplayPort. Please note that your video card must support this connection interface.

What else to look for when choosing a gaming monitor?

If we choose the best gaming monitor, we need to analyze the parameters and technical issues carefully.

It is not only the size, format or resolution of the screen that matters, but also the following:

  • Wall Mount Adaptation – If you have an empty wall above your desk, you may want to consider wall-mounting your monitor, but then you need to find a VESA-compliant model.
  • Built-in speakers – many monitors have them, but this is not the rule. If you don’t have separate speakers, you can opt for a monitor with built-in speakers, but don’t expect high sound quality from them.
  • Rotating Screen (PIVOT) – This option is useful for gamers as for buyers looking for a monitor for games and work (for example, graphics, design, and programming). The ability to rotate the screen vertically allows you to work with materials in a vertical layout comfortably.
  • Screen Height Adjustment – Many gaming monitors have a height-adjustable base, which is a great solution especially when users of different heights use the monitor – the ability to adjust the position of the monitor to the user’s height improves ergonomics.
  • Synchronization – Many gaming monitors may be equipped with refresh rate synchronization (AMD FreeSync or NVIDIA G-Sync). This is a good solution when you have a compatible graphics card, because then the refresh rate matches the generated frames.
  • HDR – This solution can be found in more expensive gaming monitors. The offer of HDR gaming monitors is small, but you should be interested in this technology. An HDR gaming monitor provides stronger screen backlighting, better reproduction of colors, highlights, and shadows.
  • Brand – It’s worth looking at the manufacturer’s reputation because it often goes hand in hand with the quality of the solutions offered, or at least with the reliability of specifications and descriptions.
  • Design – A gaming monitor should perform well in games and look good on a table. It is worth choosing the appearance of the monitor by your preferences.
  • Price – many buyers start with an affordable budget. This is a good approach as it allows you to restrict the selection to a specific price range – perhaps one of the more expensive models will impress us with parameters, and we will decide to postpone the purchase until prices drop.
  • Popularity with buyers – It is good to use social signals to make sure other users receive your chosen monitor well. We can look for answers to questions such as, for example, which gaming monitor has the highest rating among real users.
  • Release date. The latest gaming monitor is more likely to find the most up-to-date solutions than a device released many years ago, which is expected to be equipped with an outdated interface and, in general, older technological solutions.

How to set up your gaming monitor

The comfort in-game is influenced by the quality of the selected monitor and the corresponding settings. The position of the screen on the table is essential and the display parameters of the image.

What do you need to remember?

  • The monitor must be in front of the user, any installation at an angle forces you to take an uncomfortable position, leading to back pain. In terms of ergonomics, monitors with adjustable height and tilt are the best choice.
  • The monitor should be at a suitable distance from the user, especially when the screen is large – and an ergonomic solution is considered to be about 40 cm between the user’s face and the surface of the screen (but maybe larger).
  • The monitor needs to be tuned in terms of image parameters – devices can have game modes ready, but you can also create your profile with your preferred settings for color, brightness, contrast, and even refresh rate.

Offering gaming monitors can make you dizzy. There are many models of these devices, so it isn’t easy to make a purchase decision for a specific one, especially when the technical details are foreign to the buyer. Therefore, before buying, it is worth spending a little time reading about the key parameters of gaming monitors and only on this basis to decide on a specific model.

How to Install Windows 11 on an Unsupported PC

Microsoft has released a quick guide to installing the latest Windows 11 on computers with legacy hardware. Now, owners of machines without a TPM 2.0 module and with the wrong processors will be able to upgrade from Windows 10 to the “eleventh” – all you need to do is add one new key to the system registry. However, Microsoft does not recommend using its method – it can be dangerous.

Microsoft has officially allowed its latest operating system, Windows 11, to be installed on computers that do not meet the minimum requirements. The corporation has posted instructions on its product support web page to work around some of the limitations that prevent the Tens from upgrading to Windows 11.

The method proposed by Microsoft involves editing the system registry. It allows you to install a new OS on some machines without an activated TPM 2.0 module and with a processor that is not included in the system’s officially supported. Keep in mind that you will still need a TPM 1.2 module.

TPM (Trusted Platform Module) is a module used to store cryptographic keys in computers. It, in particular, can be made as a separate chip installed on the motherboard. 

Microsoft explained how to install Windows 11 on unsupported hardware. 

The Windows 11 Installation Methods support page emphasizes that Microsoft does not recommend installing Windows 11 on devices that do not meet the minimum system requirements. Responsibility for the result of such an upgrade rests with the user.

“Your device may not function properly due to compatibility issues. Devices that do not meet these system requirements will no longer be guaranteed to receive updates, including but not limited to security updates, ”warns Microsoft.

Open Microsoft support website. Download Windows 10 disk image and download Windows 11 disc image.

The media creation tool is the easiest method to download Windows 10 disk images.

Next, download Windows 11 disc image.

Navigate to the Windows 11 ISO page

Select Windows 11 from the menu under download Windows 11 disc image. Click download.

Click the download button that appears.

The ISO file will now download to your computer.

Extract the Windows 10 ISO and Windows 11 ISO files.

Next, Navigate to the Windows 11\source folder. Find and delete the install. esd file.

Next, Navigate to the Windows 11\source folder.

Find and copy install.wim, then Navigate to Windows 10\source folder and paste it here

Next upgrade to Windows 11.

Double-click the Setup file to begin the Windows 11 upgrade process.

Click the “Change how Windows Setup downloads updates” option. Select the not right now option.

Click the accept button to Accept to the terms.

Click the install button to upgrade while keeping your files and apps.

Once you complete the steps, the setup will continue upgrading the device to Windows 11.

What Is Aptx Audio Codec

The popularity of headphones raises the question for users of which models are better to choose and how they generally differ. Many people look at such a parameter of headphones as the supported codecs. The more of them or, the better they are, the better the model. However, additional nuances must be taken into account.

AptX HD is the most optimal Bluetooth codec that allows you to transfer sound in quality close to CD. This codec gives the optimal ratio of sound quality and communication stability in terms of the set of parameters. It significantly loads the Bluetooth transmission band but at the same time gives a very decent sound.

What is a codec

A codec is a program that compresses music or other content. It allows you to reduce the size of the original file without spoiling the quality.

The file size is not essential when listening to music from a smartphone with wired headphones since digital data is converted into an electric current inside the phone. Then the analog signal is sent through the wires.

In the case of wireless audio, you need to send the music digitally to your headphones. At the same time, the channel for data transmission via Bluetooth is minimal. Usually, you can’t send music at speeds over 1 Mbps, and the “reference” CD quality requires 1.4 Mbps. That is why it is necessary to compress the file using a unique algorithm – a codec – and send it to headphones that “understand” this algorithm to decode the compressed file.

Both devices – smartphones and headphones – must support a specific codec. For example, if a smartphone does not support the aptX codec, headphones are meaningless.

When reading anything about Bluetooth, you invariably come across many numbers, letters, and other obscure characteristics. One such technology is aptX HD, which adds “HD” to the mysterious attributes of the previous version of the codec. We all know “High Definition” behind this acronym, but what about “aptX”? And what is the difference between aptX (in fact, also an HD codec) from its successor?

AptX technology is increasingly mentioned, which is necessary for high-quality wireless sound, but it is still not the most widespread and affordable.

AptX is a licensed Qualcomm technology that requires bi-directional support from both the host device and wireless headphones.

Types of Codecs

There are several codecs: SBC, AAC, aptX, LDAC. 

  • SBC ← standardized in A2DP, supported by all devices
  • MPEG-1/2 Layer 1/2/3 ← standardized in A2DP: the well-known MP3 used in digital TV MP2, and the unknown MP1
  • MPEG-2/4 AAC ← standardized in A2DP
  • ATRAC ← old codec from Sony, standardized in A2DP
  • LDAC ← new codec from Sony
  • aptX ← codec from 1988
  • aptX HD ← same as aptX, only with different encoding parameters
  • aptX Low Latency ← completely different codec, no software implementation of aptX with reduced buffer
  • aptX Adaptive ← another codec from Qualcomm
  • FastStream ← Pseudo codec, bidirectional SBC modification
  • HWA LHDC ← new codec from Huawei
  • Samsung HD ← supported by 2 devices
  • Samsung Scalable ← Supported by 2 devices
  • Samsung UHQ-BT ← Supported by 3 devices

It may seem as if aptX is some kind of ultra-modern development, but it appeared back in 1988. Then it was only patented, and in technology, it began to be used only in the 2000s, but even then, it cannot be said that aptX was widespread.

The popularity came only in 2015 when Qualcomm acquired the codec and began to license it. The codec uses its compression algorithms, which allow you to keep much more of the original frequency range of the composition.

The SBC codec, a standard part of the A2DP profile, can transmit audio at bit rates up to 328 kbps at 48 kHz. But aptX can already output up to 384 kbps.

In the case of SBC, any music will sound like MP3 of average quality, but aptX is capable of producing the maximum sound quality for MP3. In addition, aptX has a lower latency: 120ms compared to 170-270ms for the SBC.

But aptX is not the king of the party yet. A year after Qualcomm took aptX under its wing, the company developed a “doped” aptX HD codec, which already allows you to listen to music at a bit rate higher than standard MP3.

It should be noted that only those devices that have a specialized chip have aptX support. It is not possible to implement support for this codec at the software level. AptX has different versions.

LDAC: Sony’s Hi-Res codec, which, unfortunately, is not good at all. It is marketed as an audiophile alternative to all existing Bluetooth audio codecs (bitrate – 990 kbps). It uses 12- and 16-band audio separation at 48 kHz and 96 kHz, respectively.  

It is somewhat similar to an audiophile “prelude”, except that the primary bitrate consumption goes to the transmission of frequencies that the human ear simply does not hear.  

Because of this, the audible spectrum is not properly worked out, and in many of the final characteristics, LDAC is no better than aptX HD. However, the result in terms of the signal-to-noise ratio of the codec is outstanding.

Almost all Android devices that ship with Android 8.0 and higher out of the box have LDAC support. LDAC-enabled headphones are only available from Sony, so the codec is not that widespread. In addition, there are no software decoders in the public domain, which does not allow us to analyze DACs with its support fully. 

Advanced Audio Coding (AAC) is another computationally complex codec with various psychoacoustic masking. Many people mistakenly believe that AAC belongs to Apple but in fact the Cupertino’s use their own modified version of this codec. Apple AACs are licensed, but only to manufacturers of certified equipment for the company’s technology. Fraunhofer FDK AAC is used for Android.

Compared to Apple AAC, it is inferior in quality to Fraunhofer FDK AAC. However, funny enough, the quality of the Fraunhofer FDK AAC encoding is still quite different.

AAC has native tools for mixing multiple audio streams across different channels. This is used to reduce latency while simultaneously transmitting system sounds (notifications) and playing music.

As for music, here AAC “drives” music at 256 kbps, but thanks to more gentle compression algorithms, the sound quality is comparable to 320 kbps for MP3. Also, various psychoacoustic “tricks” are used to improve the auditory sound of the entire frequency range.

They differ in baud rate. For example, aptX-enabled devices can communicate at up to 384 kbps and LDAC at 990 kbps. Thus, the higher the value, the less the original file needs to be compressed, which affects the sound quality.

The more you have to reduce the file; the more information is lost. At the same time, the maximum data transfer rate requires a connection between devices of high quality. Any interference in the radio broadcast or physical obstacles between headphones and smartphones (clothes, body parts, walls) will lead to stuttering and cutoffs.

A codec is a trade-off between connection quality and sound quality. However, this is not true for all algorithms. Some codecs support dynamic bit rates. They can automatically decrease the speed indicator when the signal quality drops and vice versa. These codecs include Samsung Scalable, aptX Adaptive, and SBC.

The codecs also differ in the compression algorithm. Some codecs use psychoacoustics; that is, they remove those sounds from the original that a person cannot hear anyway. For example, all quiet ones are drowned out by louder frequencies. All sounds above a specific frequency are also removed. They are mainly able to hear only children since the hearing threshold decreases with age.

The complex the compression algorithm, the better the sound will be at the same bit rate since one codec will remove any information, and the other will remove what is already inaudible, which means it will leave audible information without strong distortion.

How is AptX different from other audio codecs?

Conventional audio codecs are based on a technology called psychoacoustics, whereby fragments of musical notes that may not be heard by the human ear are removed to compress the file.

Since a precise technical explanation is beyond the scope of this article, let’s briefly describe the process.

AptX works very differently in this regard. It processes the difference in sound notes between a specific time interval and transmits it, resulting in clearer and cleaner sound quality.

Benefits of AptX

  1. High-quality wireless sound
  2. Low latency (minimum latency) music playback
  3. Drains less battery
  4. Clear and crisp hands-free voice calling

Does AptX work with iOS devices?

Unfortunately no. AptX is licensed technology from Qualcomm and currently only works with Android devices.

Apple uses the AAC codec for Bluetooth streaming and is significantly less efficient than AptX for audio processing.

How aptX, aptX HD and aptX Adaptive codecs differ

aptX, aptX HD and aptX Adaptive are popular codecs from Qualcomm. Many smartphones support them, but they are rarely used in headphones since manufacturers pay for the codec.

Codecs do not use psychoacoustics but do support high bit rates. For aptX, the figure reaches 384 kbps, aptX HD – 576 kbps, and aptX Adaptive – 276-420 kbps.

Dynamic bit rate is supported only by the newest and highest quality codec: aptX Adaptive. Thanks to its state-of-the-art compression algorithm at 420 kbps, it delivers the same quality as aptX HD at 576 kbps. If the connection is poor, the speed will automatically drop to ensure a good connection.
