General problems
Problem Solution
Video image is unsatisfactory. • Adjust display settings (see
page 19).
• Try reducing the refresh rate of your
graphic card’s output.
• For monitors with KVM extender
option:
• Adjust focus and/or brightness
dials on the remote unit of the
KVM extender.
• Consider adjusting KVM extender
cable-length jumpers (see page
57).
• Refer to the “video” section of the
troubleshooting chapter in the
KVM extender manufacturer’s
manual.*
No video image. • Make sure that the monitor is powered
up. Listen for the sound of a fan.
• Check the video extension cables
(and, for units with the KVM extender
option, check the CAT5 interconnect
cable) to be sure that all connectors
are properly and securely attached.
• Make sure that the host computer’s
monitor resolution is set for no higher
than 1024 x 768.
