10-bit Colour Depth Support

[SpriteAlpha]

Does anyone know which graphics cards support 10-bit colour depth? Thanks.

Anything with Displayport or HDMI 1.3. Most '10 bit' monitors at the moment are simply 8bit with dithering though, so it's questionable whether it's worth swapping your GPU out for.

nVidia 200 series and higher support it in hardware but not sure about outputs.

Pardon the ignorance but what's the point in 10bit colour when you have 32bit?

32-bit colour is actually 24-bit (8 bit per component), padded to 32-bit for alignment/performance reasons.

10-bit colour would refer to 10 bits per component, 30 bits total, giving four times the resolution in each component, or 64 times the total colour resolution, than 24-bit (so called 'Truecolour')

32-bit is 8-bit per RGB + 8-bit Alpha Channel.
