For a while now I've been using one 1080p display with my AMD 7950. Recently however, I've come into possession of another screen, albeit one with a 1600 by 900 display. I've been trying fruitlessly to get the monitor to work. I've been using the VGA port on my non-used Haswell card's integrated graphics to use the monitor, without success. Windows recognises the monitor in Control Panel, but nothing beyond that. I'm running Windows 7 Ultimate, and I'm totally clueless. Any ideas?
