4. Troubleshooting
4.1 Problem Solving FAQ
1. What are the Cable Length Limitations?
The switcher cannot be used as an extender. Therefore it is best to
plug the output of the switch directly to the display device and use
input cables that are 5 meters (16 ft) maximum. In other words, try
to keep the total length of cables from the video source to the box
and from the box to the monitor should not exceed 16 feet. At
longer distances you may experience video degradation. If you
cannot use shorter cables, try to turn the refresh rate and/or
resolution of the video signal lower.
2. What about HDCP (High-bandwidth Digital Content
Protection) in home entertainment systems?
The switcher is designed to primarily work with PC’s with DVI outputs.
If you want to use it in a Home-Theatre setup with DVI connections, it
may or may not work. The switchers do not provide compatibility with
HDCP encoded video sources. For example if you have a DVD player
with DVI output, depending on the brand, or the DVD, it could enforce
HDCP content protection. If HDCP is not enforced, then the switcher
will function well, however if HDCP is enforced, then at best the DVD
player will output at 480p mode, and at worst it will not output any
video on its DVI output instead a message will be displayed to use
another output!.
