DVI is so last year

225Mhz of duel link 12-bit colour glory, when do we see this on retail products?

DUEL link? So they actually shoot it out at noon in front of the General Supplies store?

Actually, there's talk about the PS3 being equipped with the latest HDMI standard which is supposed to support 12-bit per channel color. Not that it'll matter much, because human eyes have trouble resolving even 8 bits per channel of color resolution... It's like the popular trend of creating audio formats with samplerates whose upper range is only enjoyable by dogs and bats and such.

12-bits per color channel is very useful for image processing which in this context means any color, contrast or gamma adjustment done in a digital flat panel (and in some cases brightness too unless the brightness setting affects only the backlight in case of TFTs). Do processing with 8-bits only and there will be visible banding in grayscales.

ermh...
Is that a brain fart ?
I think that with the whole "HDR" thing, you would know that bit depth alone is far from enough to correctly express a color range.
RGB is a poor color space, which needs higher than 8 bit per component depth to cover a range seen by the human eye...

Sampling rate has little to do with signal range. The first is how often you sample a signal, the second is the range of signal you sample; an alternate view is that the first is horizontal resolution, and the second is vertical resolution.

Well, its not quite 12-bit, but ATI are already supporting 10-bit display pipelines with two dual-link TMDS's integrated into the X1000 series, with the capability of running up to 16-bit per component displays (obviously, their optimum will be 10-bit displays).

Not even close. You forget that 8-bit color gives you only 256 gray levels, which is woefully inadequate. For human observers, to make sure there is no perceptible banding in any situation, 14 bits of gray scale is necessary. This is especially true for specialty applications such as vision research, but even everyday applications can readily benefit from more than 8 bits.
