Ever since I setup a KVM switch to have 2 computers sharing 1 monitor/keyboard/mouse, I have had monitor problems.

There is a subtle but noticeable wobble/ wavey-ness thing happening across the screen.

Also, my display has a stretched horizontally look. I have tried different screen resolutions but they all give this stretched look which I didn't have before.

Also, my monitor used to have 1920 x 1080 as an option for max resolution, but this is now capped at 1600 x 1200.

Please help as this is very annoying & looks awful. The specs of the KVM switch say "Max. Resolution: 1920 x 1440. Bandwidth: 200MHZ"
Video card ATI Radeon HD 4300/4500 series

If you can't set either PC to the monitors native resolution (1920x1080 ?) then the culprit could be the cables from each PC to the KVM or the cable from the KVM to the Monitor. Some cables don't connect all the pins and this can stop the PCs from getting the correct resolution info from the Monitor. What sort of connectors are on those cables ?

I should clarify, this issue is only happening to 1 computer. The other one has 1920x1080, no problems.
I tried swapping the cables & restarted: the problem persists :(

Ok, the problem computer probably needs the Video driver re-installed or updated.
