I'm interested if there are any monitors out there that support 30-bit color (10 bit per pixel)? 1080P and up would be good, as would tolerably low latency.
Most 10bit color and 12, 14 and 16 bit monochrome displays use 8bit panel + FRC + dithering + LUT / 8bit panel + dithering + LUT.
Only very-high end displays designed to display static image can display 10bit natively and I only known of one, which was designed and manufactured by NEC (forgot the model number). It should be here
PS: I am aware of the existence of 10-bit column drivers and 10-bit LVDS, but I yet to see any solid evidence that they are currently in commercial use.
