IV. GETTING THE BEST RESULTS
Many factors influence the quality of a digital video signal in any applica
-
tion. When additional interconnects are put into the system, the pos-
sibility for signal degradation arises. Below are some things to keep in
mind in order to ensure the best unit performance:
• Output source device - The quality of the output signal will depend
largely upon the type and quality of source device used. For instance,
some DVD players just perform better than others.
• Using Native Resolution - It is always best to set the output resolu-
tion of the source device to the native resolution and refresh rate of the
display device(s). This allows for the two units to work together in the
best fashion.
• Distance between the source and display devices - The length of cable
between the source(s) and display(s) should be minimized as much as
possible. When using the DVI-4141, the overall cable distance should
not exceed 10M without proper amplification.
• Connection cables - When using the DVI + HDCP 4x1 Switcher, the
highest quality cables should be used. Using DVIGear’s Super High
Resolution DVI cables will ensure the best possible signal between the
source and the display.
• Interference from nearby electrical devices - These can have an ad-
verse effect on signal quality. For example, an older computer monitor
often emits very high electromagnetic fields that can interfere with the
performance of video equipment in its proximity.
