1.3 Getting the Best Results
There are many factors affecting the quality of r esults when switching HDMI type
signals. Some basic precautions will ensure the best possible performance from
your AVT-6441 HDMI v1.4 FAST Switcher with 3D / ARC.

Output display device – The quality of the output signal will depend
largely upon the type and quality of the HDMI display device used.
For instance, some video projectors just look better than others.

Distance between the switcher, the sources and the display – This
plays a major role in the final result. Long distances are possible, but
special measures should be taken in order to avoid cable losses.
These include using high quality cables. Line amplifiers may also be
necessary for the longest runs.

Input/Output connection cables – Low quality cables are susceptible
to interference. They degrade signal quality due to poor matching and
can cause elevated noise levels. Cables should be of the best quality.

Interference from nearby electrical devices – These can have an
adverse 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.
