Troubleshooting
My computer does not boot up when connected to the KVM Switch, but
works fine when I connect the keyboard, video, and mouse directly to the
computer.
• Make sure that the keyboard and mouse cables are connected tightly between
the KVM Switch and the computer.
• Check that the keyboard and mouse cables are not crossed.
• Check the cable connections.
• Boot the computer with the port selected.
I am getting ghosting, shadowing, or fuzzy images on my monitor.
• Check that all video cables are inserted properly to the Cable Kit.
• Check that the monitor you are using supports the resolution and refresh-rate
setting on your computer.
• Lower the video resolution of your monitor.
• Check that the cable length does not exceed 25 feet.
• Check that the graphics card you are using supports the resolution and refresh-
rate setting on your computer.
• Connect the monitor directly into the computer with which you are having
trouble to see if the problem still appears.
I am getting a black screen on my monitor.
• Check that all video cables are inserted properly.
• Check that the keyboard cable is connected and inserted properly between the
computer and the appropriate port on the KVM Switch.
• Move the mouse and see if it is necessary to log in as a user.
• Connect your monitor directly to the computer to verify that your monitor is
functioning properly.
The computer does not detect a keyboard and I get a keyboard error
reported at boot up.

your computer. Tighten any loose connections.

uninstall it and then reinstall the standard Microsoft keyboard driver.
• Boot the computer with the port selected.
