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 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 parameter expresses how long an object moving in the frame is displayed on the screen until it completely disappears. The lower this indicator, the more realistic dynamic scenes look on the monitor. The reaction of the matrix to movements clearly shows the time of existence of the trail from the changing picture. The MPRT parameter is more dependent on the refresh rate of the monitor screen than on the pixel response time. To reduce its value, the Motion Blur Reduction (MBR) function is often used, which briefly turns off the backlight at the end of the time of dynamic frames in order to increase the clarity of dynamic scenes.

The maximum brightness provided by the monitor screen.

Choosing a monitor with high brightness is especially important if the device is going to be used in bright ambient light — for example, if the workplace is exposed to sunlight. A dim image can be "dampened" by such lighting, making work uncomfortable. In other conditions, the high brightness of the screen is very tiring for the eyes.

Most modern monitors give out about 200 – 400 cd / m2 — this is usually quite enough even in the sun. However, there are also higher values: for example, in LCD panels (see "Type") the brightness can reach several thousand cd/m2. This is necessary taking into account the specifics of such devices — the image must be clearly visible from a long distance.

The colour depth supported by the monitor.

This parameter characterizes the number of shades that the screen can display. And here it is worth recalling that the image in modern monitors is based on 3 basic colours — red, green, blue (RGB scheme). And the number of bits is indicated not for the entire screen, but for each base colour. For example, 6 bits (the minimum colour depth for modern monitors) means that the screen is capable of producing 2 ^ 6, that is, 64 shades of red, green and blue; the total number of shades will be 64 * 64 * 64 = 262,144 (0.26 million). An 8-bit colour depth (256 shades for each base colour) already gives a total of 16.7 million colours; and the most advanced modern monitors support 10-bit colour, allowing you to work with more than a billion shades.

Screens with support for FRC technology are worth a special mention; nowadays, you can find models marked " 6 bit + FRC " and " 8 bit + FRC ". This technology was developed to improve picture quality in situations where the incoming video signal has a greater colour depth than the screen, such as when 10-bit video is fed to an 8-bit matrix. If such a screen supports FRC, the picture on it will be noticeably better than on a regular 8-bit monitor (although somewhat worse than on a full-fledged 10-bit monitor, but “8 bit + FRC” screens are much...cheaper).

High colour depth is important primarily for professional graphics and other tasks that require high colour fidelity. On the other hand, such features significantly affect the cost of the monitor. In addition, it is worth remembering that the quality of colour reproduction depends not only on the colour depth, but also on other parameters — in particular, colour gamut (see below).

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.

Monitor colour gamut based on the Adobe RGB colour model.

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.

Specifically, the Adobe RGB colour model was originally developed for use in printing; the range of colours covered by it corresponds to the capabilities of professional printing equipment. Accordingly, support for this model and its extensive colour gamut are important, first of all, if the monitor is used in the design and layout of high-quality printed products. In the most advanced screens, this figure can be 99% or even more. At the same time, we note that Adobe RGB is wider than the popular sRGB, and the percentage figures for this model are smaller: for example, 99% in RGB often gives only about 87% in Adobe RGB.

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.
