Comparison Gigabyte G24F 2 23.8 " black vs MSI Optix G2412 23.8 " black

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.

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 time spent by each individual point on the monitor to switch from one state to another. The shorter the response time, the faster the sensor responds to the control signal, the lower the delay and the better the image quality in dynamic scenes.

Note that in this case, the grey-to-grey method is used (the turn-on time is from 10% grey to 90%). It is worth paying attention to this parameter if the monitor is specially purchased for dynamic games, watching movies and other applications associated with fast movement on the screen. And even in such cases, a reaction speed of 8 ms is quite enough; a further decrease in response time does not affect the quality of the perceived image.

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).

The vertical refresh rate supported by the monitor.

Initially, the term "sweep frequency" was used in the characteristics of CRT monitors that work with an analogue signal. By tradition, it continues to be used for LCD matrices, however, for such screens, the refresh rate is actually the frame rate. See above for more on frame rate; here we note that in this case it is not the maximum frequency that is indicated, but the frequency range supported by the monitor — from the minimum to the maximum. This allows you to evaluate compatibility with certain video cards and operating modes: the frame rate of the video signal must match the frame rate of the monitor (or at least be a multiple of it), otherwise twitches and other unpleasant phenomena are possible.

It is worth noting that the monitor usually does not support any refresh rate from the range given in the specifications, but only certain standard values — for example, 50 Hz, 60 Hz and 75 Hz for the 50 – 75 Hz model.

The horizontal refresh rate of the image on the monitor screen.

This parameter was relevant for CRT monitors, in which the image was formed by an electron beam that "ran through" each individual line on the screen and illuminated the pixels. The horizontal refresh rate described the number of lines drawn per second. However, modern LCD matrices do not use a scan, but a full-frame image. Therefore, today this parameter is rarely given in monitors, and it describes the maximum horizontal frequency in an analogue video signal (for example, via the VGA interface), with which the screen can work normally.

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.

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.
