      Loose video connection?

      Are you using a video keyswitch? Does the issue continue if you swap connections on it?

      Video card going bad?

      Bad video cable?

      Bad video switch?

      Connect a monitor to each video output of the system at issue and see if the problem is resolved. Then troubleshoot out by swapping cables and connections.

      Hello…

      BFilm has covered this.

      If you eliminate all of BFilm’s suggestions as the cause, you might be able to workaround/fix this problem by adjusting the video refresh rate on the system having the problem.

      Also: If you have less than heavy-duty VGA cables, you might try rerouting the one for the “problem” system. EMI (Electro Magnetic Interference) from things such as electric fans can cause display problems.

      With today’s high-frequency monitors, you really must have high quality VGA cables and a quality non-mechanical KVM switch.

      Good luck!
