Both monitors are connected with DVI to my nVidia GeForce 7600GT.
I have also connected the second monitor with a VGA cable (monitor has both inputs) and a DVI adapter, and the display is detected and works in windows, but picture quality is crap (severe streaking and pulsing lines); I would prefer to get the DVI connection working in Windows so I can tolerate looking at the monitor.
