flickers from the second one for some reason. My first thought was the video
card so I ordered an new video card and installed it and nothing changed. My
second thought was KVM switch so I completely swapped the KVM switch over
cables and the problem remained with the same computer. Si I now Know:
1) The video card is fine
2) Nothing is wrong with the monitor as any other computer plugged into the
same cable displays fine.
3) Nothing is wrong with the KVM switch as swapping it around made no
Where do I go from here? What else could cause a monitor flicker?
Re: Monitor flickers
You should have tried directly connecting the monitor to the PC that
shows the problem, completely eliminating the KVM from the config.
Keep analysing what is different.
You dont say exactly what the 'flicker' consists of.
Check what refresh rate the monitor is being used at with both systems
and if that's the same, what screen modes are being used too.
You can get a shimmer in the video image with some high current
devices like fan heaters etc and that can affect only one of the video
cards, essentially because they arent all equal on the immunity to that.
