4-Port XGA Video Splitter
4. Troubleshooting
4.1 Problem Solving FAQ
1) Fuzzy, blurry, or ghosting image at remote location
If you have a stable but somewhat blurry image (object or character
edges are not sharp), make sure that you have set the unit’s
compensation switches correctly. If you still have a fuzzy image, try
reducing the refresh rate and/or resolution of the PC. You should also
be sure to use multi-coaxial (double shielded) 75 ohm video extension
cables for best results. A ghosting image is usually an indication of
impedance mismatch of the cable.
If too much compensation is applied at the splitter, a bright and
ghosting image may also result. In this case try reducing the amount of
compensation.
2) Image exhibits steady or rolling horizontal color “hum”
bars
This is usually an indication of improper grounding either at the
sending end, the receiving end, or both. Verify that the AC line is
properly wired and that a protective ground (green) wire is established
with NO potential difference between both the sender and receiver
locations.
3) The PC does not recognize a Plug-and-Play monitor
If the PC’s Operating System is setup to detect a plug-and-play monitor
(usually in Display Properties: Advanced Settings), it may have trouble
finding a monitor if no local monitor is hooked up to the splitter's
OUTPUT #4. Only the ID information of the monitor at OUTPUT #4
is passed to the PC. If the PC does not produce an image due to this,
