I have a 3 screen display, two NVIDIA cards; NVIDIA GeForce 6600 GT AGP, and NVIDIA GeForce FX 5200 PCI. I can display a desktop of 3072 X 768 with no problem, but I can't get SS to display across all three screens. If I set SS in the window mode, I can stretch it across about 2 2/3 screens, but not all three. Anybody?
