Hello,
 
Does anybody know the LUT entry depth of GTX 970 cards over DVI? Is it limited to 8-bit?

I would like to upgrade from a Radeon HD 5850 and a 10-bit LUT is a feature I wouldn't like to lose, for gamma calibration purposes.
 
Please note I am not talking about 10-bit per channel (deep color) output here.

Thank you very much in advance! :)

    Well, I got a reply from the German Tech Support Manager. It might interest anyone looking for an answer.

    So how does this get enabled?  When I plug the HDMI cable into the 10-bit port on the TV, the TV displays an HDMI mis-match with the color depth.  There are then flickering green pixels in a fairly regular arrangement across the whole screen.  That does not happen when I put the cable into an 8-bit HDMI port on the TV.  The only color thing I see when I go through the NVIDIA Control Panel is the Color Depth drop-down in the Change Resolution tab and the only option I get is Highest (32-bit).  Thanks.

    This thread is about the gamma table resolution, not Deep Color or 30-bit output. I don't think you can get 10-bit per color channel output from a GeForce card. You would need a Quadro card.

    Not really... I decided to stay with my Radeon HD5850 for the time being... Most probably I will upgrade to an AMD card once again, just to be safe...
