The image is not sharp, or is badly smeared.
Have you adjusted the video equalization? Follow the instructions on

page 52)?

securely.

Colors appear to be separated and there are colored borders on text and
icons.
Have you tuned the video signal and set delays to correct skew? Follow
the instructions on page 24. See Appendix D for advanced cabling
information.
Check the Interconnect cable between the Remote and Local Units. Is it

Have you powered the Local Unit? The Local Unit gets its power from
the CPU through the keyboard connection and it will not operate
without it. Use an external 5V PSU as described on page 35.
