Hi guys. Just bought PNY Quadro 400 ( http://www.nvidia.com/docs/IO/40049/nv-ds-quadro-400-nv-us-lr.pdf ) and Asus PA246Q. Both supports (on the paper/specs) 10-bit color and I needed only that, in fact. But after all this I just cannot activate that mode! In my windows 7 just 16 and 32 bits color depths are active, deep color isn't available ;___; I've tried nvidia control panel but same result there - no deep color at all :C Maybe there is something I missing? Thanks in advance. Upd.: the monitor is connected through DisplayPort, off course.
