View Full Version : 8500GT Vista suddenly left shifted
06-26-10, 09:58 AM
The other day I noticed my Vista system suddenly developed a left shift of about an inch on my display (black bar on right side). I have 3 systems using the same keyboard, mouse, and monitor on a KVM switch, and the other 2 are Windows XP and Linux which still display just fine. All three systems are running at 1680 x 1050 @ 32bit, so I know the monitor is fine as it is only the Vista system that has the skew. I was running nVidia driver ver 195.62 and tried updating to ver 257.21 but it didn't help. The weird thing is, if I switch to any other resolution on the Vista system the display will be centered once again (for instance, 1600 x 1024), so it is only the 1680 x 1050 res that exhibits the problem. I would prefer to run in 1680 x 1050 as that is the native resolution of the monitor. Has anyone else seen this problem, or have any ideas why this would suddenly occur?
Display: Acer 3216W LCD (22 inch)
Card: MSI 8500GT PCIe
Mobo: Gigabyte M61SME
sounds like you havn't done any trouble shooting yet. bypass the kvm and hook the monitor up directly to see if its the kvm. also does that resolution left shift on any of the other computers? knowing these 2 things will produce an answer on who is causing it.

I tried bypassing the KVM - same result. As I already mentioned, the other 2 systems (XP & Linux) are still displaying just fine at 1680 X 1050. The thing that puzzles me is when I switch to 1600 X 1024 it works perfectly, which has to have similar bandwidth requirements. The problem could be the NV8500 hardware, but seems more likely, a recent driver update. I was mainly wondering if anyone else has seen this problem besides me.
A driver wouldn't cause a shift like that. Clearly one of the components on the video card that handle the signal after it leaves the chip are going bad.

Bought and tried a new 9500 board with same result, so it's almost got to be something in software.
Check if Vista has a monitor driver installed.
