Hello! I'm running two ATI HD 6870 in crossfire on a win7 machine. I was trying to get a dual display one through the lower DVI and the other through an HDMI. I can get both to display though only one at a time. I am unable to display both of them at the same time. Any one have any idea?
Do you have a display connected to the upper DVI port? If so you can't use the lower DVI and HDMI at the same time, the card can only use 1 DVI and 1 HDMI simultaneously, all other displays can only be connected via DisplayPort. If you don't have a display connected to the upper DVI, try switching your DVI display to the upper port, it could be the card will only run DVI and HDMI when the upper DVI port is populated, but not the lower one.
