6.Troubleshooting

6.1Video

The image is not sharp, or is badly smeared.

Have you adjusted the video equalization? Follow the instructions on page 29.

Check the Interconnect cable between the Remote and Local units. Is it of the recommended type (see page 19)? Is it intact along its entire length and securely connected at both ends? Is it wired correctly (see page 56)?

Ensure that all video connections throughout the system are attached securely. Are you using an LCD panel? You need to adjust its clock and/or phase.

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 29. See Appendix D for advanced cabling information.

Check the Interconnect cable between the Remote and Local units. Is it of the recommended type (see page 19)? Is it intact along its entire length and securely connected at both ends? Is it wired correctly (see page 56)?

I can’t get enough color delay to correct skew.

See Appendix D: Advanced Cabling Issues (Skew), page 55.

I can’t get rid of bright ‘ringing’ after characters.

See Appendix D: Advanced Cabling Issues (Skew), page 55.

I only need video extension – not keyboard or mouse - but I can’t get a picture.

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 39.
