6. Troubleshooting

6.1 Video

The image is not sharp, or is badly smeared.

Have you adjusted the video equalization? Follow the instructions on page 30.

Check the Interconnect cable between the Remote and Local units. Is it of the

recommended type (see page 20)? Is it intact along its entire length and securely

connected at both ends? Is it wired correctly (see page 30)?

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.

Check the Interconnect cable between the Remote and Local units. Is it a

recommended ‘low skew’ type (see page 20)? Is it intact along its entire length and

securely connected at both ends? Is it wired correctly (see page 46)?

You can check whether skew is a problem in your system by viewing the test card

at: http://www.blackbox.com/tech_support/ts_upgrades/ts_ss.html.

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 34.

The monitor sometimes goes blank for a second or two.

Check that the interconnect cable is not routed near power lines or other sources of

electrical interference. Use shielded STP/FTP cable instead of UTP cable and

ensure the shield connection is maintained between the Extender units.

Check system grounding.

If this is a persistent problem, contact Technical Support.

The PC won’t boot into the correct graphics mode.

Check that DDC Emulation is enabled (see page 32). If you are using a non-

standard resolution, transfer the monitor’s DDC information to the Local Unit (see

page 33).
