I have searched the net now for two days for a software that can rotate the screen on my PC so that I can mount my Sony VPL CX1 upsidedown on the celing. The only program I have found is a Tweaker for the ATI radeon, where you can rotate the screen to any angle. But I don't have a ATI Radeon, I have a Geforce and want to keep that. Is there anyone who have a program that could do this or similar? Regards.
