I have a Dell XPS 9100. I was told it would support 3 monitors with the HD 5670 card installed. It had a VGA, DVI, and HDMI slot. While I could get each individual port/moitor to work and all in combinations of 2 at a time I could not get all three up simultaneously.
I purchased a IceQX Radeon HD 6950 and have instqalled the card and drivers, however the problem perists. All three are visible, and I can activate them in any combination of two. But I can not activate all three simultaneously.
What am I missing?
