The monitors manufacturers can specify the color depth or the amount of transmitted colors. The monitor screen can reproduce colors with the number of colors such as 8 bits, color has a depth of 2 to 8 degrees, this means that a single color can be displayed with 256 shades in turn shades can be combined display matrix may reflect the three color (blue, green red) the number of colors in 8 bit monitor matrix will 256x256x256 = 16777216 it to 16.7 million colors.
6 bit - 0.26mln. colors, cheapest monitors are used for office work, it is not designed to work with graphics.
8 bit - 16.7mln. colors, mid-range monitors are suitable for graphics, not professional.
10bit - 1,07billion colors, such monitors are suitable for working with photos and other works requiring high quality color transitions.
Computer Video Card is able to transfer the color depth is usually not less than 8 bits, and the more powerful 10-bit.
To adapt to the capabilities of graphics cards monitors, was coined by dithering or technology (FRC) Frame rate control. To create a greater number of colors was invented to make blinking pixels. Due to this improvement the visual perception of shades of colors became more and matrices were designated A-FRC.
(8bit + A-FRC) - if the characteristics of the monitor to meet such designation is necessary to understand that the actual monitor can display an image with 8-bit, but it is applied FRC technology and visual image will be comparable to the monitor having a color depth of 10 bits.
But why is it necessary, studies have shown that most people can distinguish up to 10 million colors, and depending on the level of the physiology of individual perception of colors ranges from 3,000 to 10 million. People can recognize millions of colors 1-3 by 1000. So why 10-bit panel, if a person is unable to recognize a greater number of colors. The answer to individual perception, who sees more shades with red or green.
But to solve the majority of problems with the graphics is enough 8-bit monitor.
