I am desperate for help here.
I have a brand new system the I just built using the Gigabyte GV-R6750C-1GI video card running Windows 7 Pro 64-bit.
Everything was fine until I extended my desktop across to the 2nd monitor. The 2nd monitor flickers either a black bar across the top or bottom of the screen or just flickers a mirror stamped image just slightly offset of itself.
I have worked with Gigabyte Tech support and was told to update my drivers which I have the latest Catalyst driver installed and the problem did not go away. Gigabyte told me I must have a defective card so I RMA'd my new card and received a brand new one as replacement from my vendor. The same exact problem with the new card. I then uninstalled the AMD/ATI drivers & catalyst software, rebooted, reinstalled and rebooted again. Same problem. I then rolled back the driver to my Dual Samsung SyncMaster 2433BW monitors to an older XP/VISTA driver and same problem.
I have changed some misc settings on the 2nd monitor in the Catalyst software and with any change at all, doesn't seem to matter what the change is, the problem moves to the 1st monitor. With any other change, it moves back to the 2nd. It seems to flip flop back and forth with any video configuration change. Never both monitors at the same time, only one at a time has the trouble.
I'm an IT professional here and I can't figure this out. My best guess is that there is some inconsistency with this video card and my monitor but what it is, and how to fix this problem aside from buying 2 new monitors and a different video card, I have no idea. There has got to be a way to fix this. I have read over 50 threads around the net with people having the same problems and they only things that are in common are ATI Video Chips and Extended Desktops.
I would be very thankful for someone to solve this problem for me since myself nor Gigabyte has any answers.
Thanks.
