[citation][nom]AndrewCutter[/nom]is there any lcd screen out there on which i can do video post processiong on my 16 bit renders. To the best of my knowledge the most a lcd screen support is 8 bit. I just asked as it is mentioned here that graphics pros will find this usefull. So does that mean that this can support true editing of 16 bit and 32 bit float files.....[/citation]
There's a bit of a difference between the two values that you're talking about. 24-bit color, in the traditional sense (also known as "true color") can display just over 16.7 million distinct colors, all within the RGB color space.
An 8-bit monitor (usually with IPS panels) does display 24-bit "true" color (i.e., 16.7 million distinct colors). A 6-bit monitor (TN-panels, usually), however, can only display about 262,000 colors. It displays the rest of the color spectrum by effectively blending colors next to each other - so you can't get "true" color out of a 6-bit LCD.
When a monitor is labeled "8-bit", that doesn't mean that it can't display 24-bit color. An 8-bit monitor simply uses 8-bits to represent red, 8-bits for green, and 8-bits for blue (2^8 x 2^8 x 2^8 = 16.7M). A 6-bit monitor, on the other hand, uses only 6-bits for each, and therefore produces far fewer distinct colors (2^6 x 2^6 x 2^6 = 262,144).
And FYI, "32-bit color" doesn't *usually* refer to actual 32-bit color. It's usually 24-bit color with 8 bits of non-color data. However, there are some 10-bit LCDs showing up on the market these days that can display more colors (2^10 x 2^10 x 2^10 = over 1 billion distinct colors).
For most purposes, you shouldn't need more than an 8-bit LCD panel.
