Product type

— Monitor. In this case, we mean monitors designed mainly for classic use — as a screen for a personal computer. Their functionality can be quite diverse — from entry-level screens with 1-2 inputs for connection to multifunctional models with built-in speakers, TV tuners, remote controls, etc. The same applies to the diagonal. Most traditional monitors are in the 22-30" range (these sizes are currently considered optimal for screens whose distance is determined by the width of the desktop), but there are also large-format devices whose diagonal can exceed 32".

Portable monitor. A separate caste of monitors designed to connect to laptops. They are distinguished by small diagonal sizes, not exceeding 18", a thin format and the absence of a stand, as a result of which they look like tablets.

Game monitor. Monitors considered optimal for gaming. These are not necessarily devices specially designed for this application (although there are some); however, all gaming monitors have a number of features that gamers will surely appreciate. Firstly, the resolution (see below) in such models is not lower than Full HD. Secondly, the matrices have a low response time — less than 5 ms, which allows high-quality display of dynamic scenes; and the frame rate often reaches 120 Hz or even more (although there are quite modest values). Thirdly, devices of this type often have special gaming (see below...) and similar features — in particular, most gaming monitors are compatible with FreeSync and/or G-Sync technologies (see "Features").

LCD panel. One of the key features that distinguish LCD panels from conventional monitors is the wide variety of connectors: in addition to video outputs, it includes auxiliary ports such as LAN or RS-232 (see "Connectors (Optional)"). It is also believed that the LCD panel must be hung on the wall without fail, but this has its own specifics. Many devices of this type are really made only for wall installation, and some models can be combined into a video wall that broadcasts one image to several screens. But besides this, there are solutions equipped with stands and allowing desktop use (and sometimes even originally designed for it). At the same time, the first variety, "purely wall-mounted", can have almost any diagonal — including modest 21 – 22 "; but the dimensions of "desktop" panels start at 32", moreover, they most often have advanced matrices like IPS. Anyway, such screens are used mainly in rather specific areas. So, wall mounting is convenient for organizing information boards at stations, airports, shopping centers, for use at exhibition stands, conference rooms, etc. Desktop models are useful for those for whom large size and high image quality are of key importance . Also among them there are many devices with touch screens, which further expands the user experience.

— Plasma panel. These types of devices are similar in many ways to the LCD panels described above, but they also have some key differences. The main one is the technology used for the screen: instead of a liquid crystal matrix, plasma panels use cells filled with a special gas and covered with a luminous substance — a phosphor. This technology provides very high image quality, with deep colour reproduction and contrast. At the same time, it is not easy to create a small plasma cell, which is why the pixels on this type of screens have more stringent restrictions on the minimum size. As a result, plasma panels, in principle, are never small — 42 "is considered almost the minimum size for such a screen. In addition, the reverse side of the described advantages is also a slightly shorter service life and higher cost than LCD matrices. As a result," plasma" has not received much distribution, such devices are bought mainly not for "public", but for personal use — for example, as a home theater screen or as equipment for an advanced gamer.

Video wall. Models designed to build video walls. Such a wall is an array of numerous closely arranged screens that can work in concert and produce a large overall image; each screen is responsible for its own fragment of the picture. Such designs are used, in particular, at concerts and other public events, where there are no longer enough separate screens. The main feature of monitors for video walls is a very thin frame — due to this, the boundaries between the segments are almost invisible, and the image is perceived as a whole.

Information display. Narrow-purpose equipment, assuming a stationary method of installation. Such displays are mounted on the wall, built into special niches or openings. They are intended to work as digital signage, broadcast advertising materials, play various video content. Individual instances of information displays can support touch control, have a pre-installed Smart operating system and other "smart" features. As a rule, specialized proprietary software is used to control the operation of such equipment.

Size

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.

Surface treatment

Modern monitors can use displays with both glossy and matte screen surfaces. A matte surface is in some cases more preferable due to the fact that on a glossy screen, when exposed to bright light, noticeable glare appears, sometimes interfering with viewing. On the other hand, glossy screens offer better picture quality, higher brightness, and richer colours.
Due to the development of technology, monitors with a special anti-glare coating have appeared on the market, which, while maintaining all the advantages of a glossy screen, creates significantly less visible glare in bright ambient light.

Pixel size

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.

Response time (GtG)

The time each individual pixel on the monitor takes to switch from one state to another. The lower the response time, the faster the matrix responds to the control signal, resulting in less delay and better image quality in dynamic scenes.

Note that in this case, the gray-to-gray method is used (the time it takes to switch from 10% gray to 90% gray). Pay attention to this parameter if the monitor is specifically purchased for fast-paced games, movie watching, or other applications involving quick screen movements. However, there’s no need to chase the fastest models. It’s not often possible to discern the difference between 1 ms and 5 ms. For most scenarios, monitors with a 4 ms response time will suffice. In any case, it’s best to rely on live impressions for a true comparison.

Refresh rate

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

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.

Colour space (NTSC)

The colour gamut of the monitor is based on the NTSC 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, NTSC is one of the first colour models created back in 1953 with the advent of colour television. It is not used in the production of modern monitors, but is often used to describe and compare them. NTSC covers a wider range of colours than sRGB, which is standard in computer technology: for example, coverage of only 85% in NTSC gives about 110% in sRGB. So the colour gamut for this model is usually given for advertising purposes — as a confirmation of the high class of the monitor; a very good indicator in such cases is considered to be 75% or more.

Colour space (sRGB)

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.
