Brightness

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.

Features

KVM switch. The presence of a KVM switch in the monitor - Keyboard, Video, Mouse. This module allows you to control two or more computers using one monitor, one keyboard and one mouse, quickly switching between different PCs (for example, a desktop computer and a laptop). A KVM switch improves productivity when you need to use multiple computers at the same time or one at a time and eliminates desktop clutter. To switch from one computer to another, just one click of the mouse in the proprietary software or a programmed button on the keyboard is enough.

Light sensor. A sensor that monitors the brightness of ambient light. It is mainly used to automatically adjust the brightness of the monitor itself to the specifics of the situation: for example, if the room gets dark, the image on the screen can also be made dimmer, and under sunlight for normal visibility, the brightness should be high. This provides additional comfort for the user and also contributes to energy savings.

Presence sensor. A sensor that detects the presence of a person in front of the screen. Most often used to automatically control sleep mode: if there is no one in front of the monitor for a certain time, the screen backlight turns off, and when the user returns, it turns back on. This contributes to energy savings and increases the life of the matrix. In addition, the sensor can b...e useful for more specific tasks — for example, to control the presence of an employee at the workplace.

PBP (Picture by Picture). Possibility to display two "images" on the monitor at the same time — from two different sources, each of which is connected to its own video input. This feature can be very useful in cases where you have to work with two devices at the same time — for example, with a laptop and the main system unit. The image from both devices is usually displayed side by side. Note that for PBP to work effectively, the screen must be quite large, so this function is found mainly among monitors with the appropriate diagonal — from 27 "and above.

Flicker Free. Brightness control technology that eliminates excessive screen flicker. The idea of this technology is to reduce the brightness of the image directly by reducing the brightness of the backlight (whereas in monitors without Flicker Free, the brightness is adjusted by turning the backlight on and off at a high frequency). Due to the absence of flicker, the load on the eyes and nervous system is reduced, and working with the monitor (especially for a long time) becomes more comfortable.

AMD FreeSync. Monitor compatible with AMD FreeSync technology. As the name suggests, this technology is used in AMD graphics adapters — so it's worth looking for a monitor with this compatibility if your computer has an appropriate graphics card. And the general idea of FreeSync is to match the frame rate of the monitor and the frequency of the video signal from the graphics card. Such a need arises in the light of the fact that in some cases the frame rate of the video signal can “float” (this is especially true for modern games and other resource-intensive tasks); and a mismatch with the monitor's refresh rate can result in jaggies, jerks, and other artifacts. FreeSync avoids this.
Note that in this case we are talking about the original version of this technology — support for FreeSync Premium and Premium Pro is indicated separately, for these versions, see below. A similar solution from NVIDIA is called G-Sync; it is also described below.

AMD FreeSync Premium Pro. The most advanced (at the beginning of 2020) version of the FreeSync technology described above, formerly known as AMD FreeSync 2 HDR. As the first name implies, one of the features of this version is HDR support. In addition, FreeSync Premium Pro claims a frame rate of at least 120 fps at Full HD resolution, as well as low frame rate compensation (LFC). The essence of this function lies in the fact that when the frame rate of the source video signal falls below the minimum frequency supported by the monitor, the same frame is displayed on the screen several times, which allows you to maintain the maximum smoothness of the “picture”. According to the creators, FreeSync Premium Pro works especially well in games; and many modern games are originally designed to work with this technology.

AMD FreeSync Premium. An intermediate option between the basic AMD FreeSync technology and the advanced FreeSync Premium Pro. Both of these versions of the technology are described in more detail above; and FreeSync Premium does not have HDR support (unlike the Pro version), but works at the same frame rate (at least 120 fps at 1920x1080 resolution) and also uses LFC low frame rate compensation technology.

NVIDIA G-Sync. A technology for matching the frame rate of the monitor and the frame rate of the video signal used in NVIDIA video cards. The need for such coordination arises due to the fact that in some cases the frame rate of the video signal can “float” (this is especially true for modern games and other resource-intensive tasks); and a mismatch with the monitor's refresh rate can result in jaggies, jerks, and other artifacts. A similar technology from AMD is called Freesync (see above).
Note that in this case it means support for the original G-Sync technology, which was originally incorporated during production. Support for the more advanced G-Sync Ultimate, as well as G-Sync Compatible compliance, are listed separately (see below).

NVIDIA G-Sync Ultimate. A variation of the G-Sync technology described above, which provides not only for matching the frame rate with the graphics card, but also for a number of improved characteristics of the monitor itself. So, models with this marking necessarily support HDR (and according to a very high standard — not lower than DisplayHDR1000), and also have an extensive colour gamut, often measured by DCI P3 (see above for both). Most of these monitors are gaming monitors (see "Type").

NVIDIA G-Sync compatible. This feature is indicated for monitors that were not originally designed for use with G-Sync technology (see above), but according to the results of testing, they turned out to be compatible with it. All such devices are models with the AMD FreeSync function (also described above), which were tested by nVIDIA and showed the ability to fully work with G-Sync as well (however, we emphasize that FreeSync support by itself does not yet guarantee compatibility with G-Sync) . Anyway, from the user's point of view, the difference lies in the fact that G-Sync Compatible monitors are much cheaper than their counterparts with G-Sync, but may be inferior to them in picture quality. This is due to the fact that these monitors do not undergo additional image quality tests that are required for devices with native G-Sync support. In addition, in G-Sync Compatible models, correct frame synchronization when working with NVIDIA video cards is guaranteed only if the graphics card is based on the GeForce GTX 10-series and GeForce RTX 20-series GPUs — these are the adapters that compatibility testing is carried out on.

Adaptive Sync. Screen support for VESA Adaptive-Sync technology. The feature aims to synchronize the display's refresh rate with the GPU's frame rate to reduce latency, minimize artifacts, and eliminate visual tearing. Adaptive-Sync certified screens should run at a default refresh rate of 120Hz, but should be able to drop the frame rate down to 60Hz. The actual response time of such displays should be less than 5 ms. It is important to note that VESA Adaptive-Sync technology is only available for DisplayPort version 1.2a or later.

CalMAN certification. The monitor has a CalMAN Verified certificate. This certification is given to high-quality screens after they have been tested and calibrated using CalMAN, a professional suite of software tools used for colour manipulation and sensor colour adjustment. The accuracy of these tools is such that even Hollywood filmmakers use them; and in the case of monitors, CalMAN certification is an additional sign of high quality — it means that the colours on such a screen will be displayed as faithfully as possible. Such models are intended mainly for professionals working with colour, as well as for connoisseurs of high-quality video content.

Pantone certified. The presence of the monitor certificate "Pantone Validated" — that is, a certificate of compliance with the Pantone colour system (PMS). This is a professional colour system created by the company of the same name and widely used in design and printing. One of Pantone's basic ideas is that each colour should remain the same at all stages of work — from agreeing on a general idea to printing / releasing the final product; To do this, all shades covered by the system are assigned code names, which are used in the work. In the case of monitors, Pantone certification means that when working with materials and software tools that use a given colour scheme, the colours on the screen will match the actual Pantone hues as closely as possible. We emphasize that there is no question of perfect correspondence (LCD matrices are not physically capable of adequately displaying some shades); in addition, monitors with such certification may have different colour gamuts — both in percentage and in the systems used for designation (sRGB, Adobe RGB, DCI P3 — see above). However, even if the colour is beyond the capabilities of the screen, it will be displayed as accurately as possible. Therefore, for professional tasks associated with intensive use of Pantone, it is worth choosing monitors with official certification; An example of such tasks is the printing of image printing.

Power consumption

Rated power consumption of the monitor. Usually, this item indicates the maximum power that the device can consume during normal operation — that is, the energy consumption at maximum brightness, the highest volume of the built-in acoustics, etc. Actual power consumption can be noticeably lower, however, when choosing, it is still best to focus on the value stated in the specifications.

In general, the lower the power consumption, the more economical the device in terms of electricity consumption (ceteris paribus). In addition, this characteristic can be useful when selecting an uninterruptible power supply for a PC and in other specific situations when it is necessary to accurately determine the power consumption of equipment.
