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).Colour depth
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).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.
