kvm and video output

[Totalchaos]

I just got a 2-port kvm to use my linux-box and my main pc at the same desk
works like a charme in linux and on the win desktop
however if I loadup Americas Army the screen flickers dramaticaly
exit the game and all is ok again

So i figured it was the kvm
I just happen to have a second, almost identical kvm
hooked that up, and yes same problem
the kvm-cables seem to be decent enough, they aren't that long at all: about 4 feet, 1.2m

so I unplugged the kvm and connected everything back to the main pc
problem solved, so I guess it's the kvm or the cable afterall

I just started AA back up and again that same problem, even without any kvm hooked up
everything is stock again
Exited the game, restarted it and perfect video
HUH come again?
I'm kinda stumped here

should I try another driver?
Any other tips?

What video card? You want a utility to allow you to lock the refresh rates. For ATI cards you can get Ray Adam's ATI Tray Tools and for Nvidia cards I use the NGO drivers as they come with a tab in the control panel that allows you to set and lock custom refresh rates at any resolution. This is an issue with XP and I don't think it is your KVM causing it. Another option that works with Directx games is to run dxdiag and go to the More Help tab, click the override button and put in your desired refresh rate. All directx games will now use this refresh rate.
