Hi, I have just upgraded my video card from Nvidia Gt420 to ATI 6970 and my Sony Bravia FullHD which I am using as a monitor have started reporting 10bit color depth instead of 12 as it was with Nvidia. I can't see any deference in picture quality but nevertheless want to make sure that it was not affected. please let me know what you think on this occasion. P.s I am using HDMI connection. Thank you!
