2.0 GETTING THE BEST RESULTS
Many factors influence the quality and reliability of HDMI switcher
installations. Consider the following and take basic precautions
suggested below to ensure the best possible performance.
•
Output display device.
The quality of the output signal depends
largely upon the type and quality of the HDMI display device used;
some televisions simply look better than others.
•
Distance between the sources and the display.
Long distances are
possible, but premium quality cables and advanced HDMI extenders
with DDC correction may be necessary for the longest runs.
•
Input/output connection cables.
HDMI cable design and quality
are extremely important in long cable runs where capacitance can
severely degrade performance. Cables should be of the best quality;
low quality cables are susceptible to interference. Always use locking
cables or good strain relief methods to prevent cables from becoming
loose over time.
•
Interference from nearby electrical devices
can have an adverse
effect on signal quality. For example, older computer monitors often
emit a very high electromagnetic field that can interfere with the
performance of video equipment in its proximity.
2.1 Resolution Tracking
HDTV signals can be output from the source at several different
resolutions and the 1392 can sense and accept any standard resolution.
However, on the outputs, the DA must sense the resolution capabilities
of all of the display devices connected to it and then set the resolution of
all outputs to the resolution of the display having the
lowest
resolution
response characteristics. This behavior insures that all displays can
produce a picture. It is best to use display devices having the same
maximum resolution; just one display with lower resolution capabilities
causes all of the other displays connected to the DA to receive that same
low resolution.
