I can play a 3D game on one screen, have Winamp & IM on the secondary, but when I click on the secondary monitor the game is minimized, unless I use a second card to take care of the second monitor. I'm not sure, but this could be a Windows limitation and not something AMD can solve.
Thanks for the suggestion. Sadly, all of my PCI slots are taken up so that's not really a valid option for me.
Also I'm pretty sure it's AMD/ATI only as my previous Nvidia 560 card worked flawlessly with dual display.
Anyone have any other ideas? I'm feeling hopeless here about to just ebay it and buy another Nvidia card.
