Curved screen
The presence of
a curved screen in the monitor design.
Such a screen has the left and right edges curved forward - it is believed that this shape significantly improves perception compared to a flat surface. At the same time, it makes sense to provide this feature only on fairly large diagonals - at least 30"; therefore, it is typical mainly for high-end models. It is also worth noting that in order to take advantage of all the advantages of a curved screen, you need to look at it from a certain point - at the optimal distance, strictly in the center; however, for computer monitors this is usually not a problem.
The main parameter of a curved screen is the radius of curvature. It is indicated in millimeters along the radius of a circle, the bend of which corresponds to the bend of the monitor: for example, the designation 1800R indicates a radius of 1.8 m.
The smaller the number in this designation, the more curved the screen (all other things being equal). At the same time, some manufacturers claim that the ideal curvature value is 1000R: supposedly, it is with this curvature of the screen that the image on it turns out to be as close as possible to a person’s natural field of vision, and the closer the curvature of the monitor is to 1000R, the better the viewing experience. However, in practice a lot depends on personal preference; and when viewed from a long distance (exceeding the radius of curvature by one a
...nd a half times or more), all the advantages of a curved screen are lost.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 (MPRT)
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.
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).Static contrast
Static contrast provided by the monitor screen.
This value describes the difference between the brightest whites and darkest blacks that the screen is capable of producing. In this case, unlike dynamic contrast (see below), the difference is indicated on the condition that the brightness of the screen backlight remains unchanged. In other words, this is the contrast that is guaranteed to be achievable within one frame. Static contrast is inevitably lower than dynamic. However, it is she who describes the basic capabilities of the screen.
The minimum static contrast ratio for tolerable image quality is considered to be 250:1, but even the most modest modern monitors give out about 400:1 (and a value of
1000:1 is not the highest class), and in high-end models this figure can reach 2000:1 and even more. .
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.
Colour space (Adobe RGB)
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.
