Video problems

• If your screen won’t show properly on your monitor, first make sure that all your
cables are firmly seated in their proper ports.

• If your screen is coming up blank or striped, the resolution on your PC may be higher
than the maximum resolution supported by the KVM (VGA 1920 x 1440). Adjust the
screen resolution and frequency until they are in the supported range.

• If there is ghosting, speckles or stripes on your screen, there may be excessive
electromagnetic interference from an external source. Check the path of your video
cable for strong electromagnetic sources like motors or power cables. Try and keep
your video cables as far as possible from these external sources.
