I have an AMD Radeon HD 7700 in a Dell XPS and want to have 3 monitors. The monitors are also Dell 2009w with DVI-D and VGA ports. My cable hookup is as follows:
Left display: Dvi-D to to HDMI cable
Center: DVI-D to DVI-D
Right: DVI-D to DVI-D/DisplayPort adapter to DisplayPort.
Without Eyefinity, I can only get 2 displays to work. If I use Eyefinity, I can get all 3 monitors to work, but when you hit the Windows start key, the menu appears on the left most screen whereas I would obviously like to appear on the center screen.
