Well, I'm upgrading my computer for 3D--getting an Acer 3D projector--but I need it to work with my Mits 3800 also. My PC has a Radeon 4200, 2 3.0ghz AMD Cpu, 1gb ram on the motherboard which works fine for my Mits 3800, but I'm switching that off and have added an EVGA GT450. When I switch over to the 450, windows 7 starts okay, goes to the flashing icon screen, then switches to a screen full of garbage pixels. I have used a regular monitor dual screen hookup and can see that the 450 is working, and it even recognizes the Mits 3800 and 1080p. I tried switching resolutions, but still nothing. I am going through a monoprice hdmi switch with a 3 foot cable out of the 450 and another 20 foot to the projector. I have not had a problem with my ati setup with two motherboards and video cards in the past with the Mits, so I think it's the Nvidia that is getting to me. Any suggestions?
