Comparison Dell G3223Q 32 " black vs Asus ROG Strix XG27AQM 27 " black

Diagonal size of the monitor matrix, in inches.

This parameter is one of the most important for any screen — it determines the total size of its working area. In general, it is believed that larger monitors are more comfortable: a large screen allows you to see a large fragment of text, images, etc. without having to scroll the "picture". On the other hand, the diagonal directly affects the dimensions, weight and cost of the monitor. In addition, it is worth remembering that screens with the same diagonal can have different aspect ratios and different specializations: for example, widescreen models are convenient for playing games and watching movies, while classic 4:3 or 5:4 solutions are preferable for working with documents. Now there are monitors of different diagonals on the market, among them the most popular are: 19–20", 22", 23 – 24", 25 – 26", 27 – 28", 29 – 30", 32", 34" and more.

The native resolution of the monitor. Ideally, the resolution of the video signal should be the same, then the quality of the image on the screen will be maximum.

In general, the higher the resolution, the higher the detail and the more advanced the screen is, but the more expensive it will cost (ceteris paribus) and the more power the graphics card will need to work properly at that resolution. As for specific values, they are quite diverse in modern monitors, but all resolutions can be divided into several general categories:

— HD (720). Screens suitable for HD video with a resolution of 1280x720. Note that this category also includes models with a resolution of 1024x768 — this figure is somewhat less than necessary to display HD in its original size, but the quality of the HD picture on such a screen still turns out to be quite high. The most popular option among HD monitors is 1366x768, there are also models 1280x768, 1280x800 and non-widescreen (5:3) 1280x1024.

— Full HD (1080). Full HD monitors. The classic, most popular version of this resolution is 1920x1080 ( 16:9 format), however, there are other options among monitors, including such specific ones as ultra-widescreen (32:9) 3840x1080, as well as 1600x1200 (a 1920x1080 frame “does not fit into it”) ” in width, but this resolution is still commonly r...eferred to as Full HD). To date, Full HD is a good compromise between image quality, screen cost and graphics card requirements. As a result, it is this format that is most popular among modern monitors.

— Quad HD. A kind of intermediate option between the popular Full HD and advanced demanding Ultra HD 4K. It covers resolutions from 1920x1440 to 3200x2400, although most modern Quad HD monitors fit into a narrower range — from 2560x1440 to 3840x1600. Such a screen can be a good option for those who “Full HD is not enough, but 4K is a lot.”

— Ultra HD (4K). This standard assumes a horizontal frame size of approximately 4000 pixels, but specific resolutions may vary. Popular options found in monitors include 3840x2160, 4096x2160, and 4096x2304. Overall, UHD 4K gives you 4 times more pixels on screen than Full HD; such resolutions are typical for high-end monitors and are most often combined with a large diagonal — from 27 "(although there are exceptions).

— Ultra HD (5K). An even more advanced standard than UHD 4K, which assumes a horizontal frame size of about 5000 pixels — for example, 5120x2160. It is used extremely rarely, mainly in top professional screens.

— 8K. Further, after 5K, the development of HD standards, which provides for a frame with a horizontal size of about 8000 — for example, one of the 8K resolution options in monitors is 7680x4320. Allows you to get extremely clear and detailed images, but such high-resolution monitors are very expensive, and it is not so easy to find a signal source in such a resolution. Therefore, only single models of 8K monitors are currently on the market.

The size of one dot (pixel) on a monitor screen. This parameter is related to the maximum resolution of the monitor and its diagonal size — the higher the resolution, the smaller the pixel size (with the same diagonal) and vice versa, the larger the diagonal, the larger the size of one pixel (with the same resolution). The smaller the size of one pixel, the clearer the image will be displayed by the monitor, the less grainy it will be noticeable, which is especially important on large monitors. On the other hand, a small pixel size creates discomfort when working with fine details and text — this mainly applies to monitors with a small diagonal.

The maximum frame rate supported by the monitor at the recommended (maximum) resolution.

The higher the frame rate, the smoother the movement on the screen will look, the less noticeable jerks and blurring will be on it. Of course, the actual image quality also depends on the video signal, but for normal viewing of video at a high frame rate, the monitor must also support it.

When choosing this option, keep in mind that at lower resolutions than the maximum, the supported frame rate may be higher. For example, a model with a 1920x1080 matrix and a claimed frame rate of 60 Hz at a reduced resolution can give 75 Hz; but the 75Hz frame rate is only listed in the specs if it is supported at the monitor's native (maximum) resolution.

Also note that a high frame rate is especially important for gaming models (see "Type"). In most of them, this figure is 120 Hz and higher; monitors with a frequency of 144 Hz are considered the best option in terms of price and quality, however, there are also higher values — 165 Hz and 240 Hz. And monitors at 100 Hz can be both inexpensive gaming models and advanced home ones.

You can evaluate all the frame rates at which this monitor is capable of operating by the ver...tical frequency claimed in the specifications (see below).

Dynamic contrast provided by the monitor screen.

Dynamic contrast refers to the difference between the brightest white at maximum backlight intensity and the deepest black at minimum backlight. In this way, this indicator differs from static contrast, which is indicated with a constant backlight level (see above). Dynamic contrast ratio can be expressed in very impressive numbers (in some models — more than 100,000,000: 1). However, in fact, these figures are poorly correlated with what the viewer sees: it is almost impossible to achieve such a difference within one frame. Therefore, dynamic contrast is most often more of an advertising than a practically significant indicator, it is often indicated precisely in order to impress an inexperienced buyer. At the same time, we note that there are "smart" backlight technologies that allow you to change its brightness in certain areas of the screen and achieve a higher contrast in one frame than the claimed static one; these technologies are found mostly in premium monitors.

Monitor colour gamut Rec. 709 or sRGB.

Any colour gamut is indicated as a percentage, however, not relative to the entire variety of visible colours, but relative to the conditional colour space (colour model). This is due to the fact that no modern screen is able to display all the colours visible to humans. However, the larger the colour gamut, the wider the monitor's capabilities, the better its colour reproduction.

Nowadays, sRGB is actually the standard color model adopted for computer technology; This is what is used in the development and production of most video cards. For television, the Rec. standard, similar in parameters, is used. 709. In terms of the range of colors, these models are identical, and the percentage of coverage for them is the same. In the most advanced monitors it can reach or even exceed 100%; These are the values that are considered necessary for high-end screens, incl. professional.

The color gamut of the monitor according to the DCI P3 color model.

Any color gamut is indicated in percentages, but not relative to the entire variety of visible colors, rather relative to a conventional color space (color model). This is because no modern screen can display all the colors visible to the human eye. Nevertheless, the larger the color gamut, the broader the monitor's capabilities, and the better its color reproduction quality.

DCI P3 is a professional color model mainly used in digital cinemas. It is significantly broader than the standard sRGB, providing more accurate and high-quality colors. Accordingly, the percentage values are lower—for example, 115% coverage in sRGB corresponds to approximately 90% coverage in DCI P3; in the most advanced modern monitors, coverage according to this standard is 98 – 100%. At the same time, supporting DCI-P3 is costly, which is why it is mainly found in high-end monitors for professional and gaming purposes.

This technology is designed to expand the range of brightness reproduced by the monitor; Simply put, an HDR model will display brighter whites and darker blacks than a "regular" display. In fact, this means a significant improvement in colour quality. On the one hand, HDR provides a very "live" image, close to what the human eye sees, with an abundance of shades and tones that a normal screen cannot convey; on the other hand, this technology allows to achieve very bright and rich colours.

Modern HDR monitors may use the DisplayHDR designation. This standard takes into account a number of parameters that determine the overall quality of HDR performance: brightness, colour gamut, colour depth, etc. Based on the results of measurements, the monitor is assigned one of the following markings: DisplayHDR 400 means relatively modest HDR capabilities, DisplayHDR 600 is average, DisplayHDR 1000 is above average, DisplayHDR 1400 is advanced. At the same time, the absence of a DisplayHDR label in itself does not mean anything: it’s just that not every HDR monitor is tested according to this standard.

Note that for the full use of HDR, you need not only the appropriate monitor, but also content (movies, television, etc.) originally created in HDR. In addition, there are several different HDR techn...ologies that are not compatible with each other. Therefore, when buying a monitor with this function, it is highly desirable to clarify which version it supports.

Display certification for safe blue light emissions and panel flicker. The presence of a certificate confirms the comfort of the screen for the eyes.

TÜV Rheinland is a large international concern headquartered in Cologne, Germany, providing a wide range of audit services. The company's specialists have developed and approved a number of tests for the compliance of the screens of mobile devices, monitors and TVs with the required level of eye protection from the harmful effects of display radiation on the user's vision on the other side of the screen. The authoritative opinion of TÜV Rheinland is respected in the tech community. Certificates from this body are issued to successfully tested electronics for the implementation of blue light filtering and screen flicker suppression technologies.
