2.0 GETTING THE BEST RESULTS
Many factors infl uence the quality and reliability of HDMI signal
distribution installations. The following are the main factors to consider,
and basic precautions that will 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.
For instance, some televisions just look better than others.
• Distance between the DA 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. Low quality cables are susceptible
to interference. They degrade signal quality due to poor conductor
matching and can cause elevated noise levels. Cables should be of
the best quality.
• Interference from nearby electrical devices can have an adverse
effect on signal quality. For example, an older computer monitor often
emits very high electromagnetic fi elds that can interfere with the
performance of video equipment in its proximity.
2.1 Resolution Tracking
Since HDTV can be output from the source at any of several different
resolutions, the 1390 series DA 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
lowest
lowest
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.
