Nvidia GT 120 512MB is the standard equipment card for my 09 machine and I have some basic questions for which I couldn't find answers. The card has a mini DP and dual link DVI. Does anyone know the color channel bit depth for the mini DP connection? I was told in another post that for this card the DVI port had 10 bits per channel while the mini DP offered 12 bits per channel. Since I am using a wide gamut monitor, 12 bits per channel would be better for me. Anyone know for sure? The card is listed as having three connectors; one mini DP and two DVI (dual link). I see only two connectors on the card. What is meant by dual link DVI? Thanks for any insights.
