Has anybody set up 10 or more monitors running in Windows 7 (64-bit Ultimate edition)? My video cards: EVGA 8200 GS cards. All of the same model. For 8 monitors with 4 video cards: Win7 was happy and ran perfectly. Yesterday I tried to add a 5th card. At first Windows kept locking up and crashing. I only found out that the card I used was bad. I put in a different one (tested as good). This time, no blue screen, but... Windows took a long time to come up from each reboot. Windows 7 sees all 10 monitors all right. But... CPU spent around 20% (i7-950 quad core processor) just tracking the mouse movement. Whenever I drag the mouse across the screen back and forth, it sent the CPU usage up high. This is not good. Back to 4 cards 8 mons, perfectly happy. During idle, CPU was less than 1% busy. Some weird thing with Windows. Sort of like the monitors placed in Portrait. If it jams the CPU to 20% busy when nothing (no app) is running. I read somewhere that said ther is no pre-determined limit on the number of monitors Windows 7 supports. It can be up to the video card vendors. If anybody has been successfully running Windows 7 with 10 or more monitors, please share your experience. And what video card(s) [make/model] do you use?
