1.3 Getting the Best Results
There are many factors affecting the quality of results when scaling video signals.
Some basic precautions will ensure the best possible performance from your
Scan Converter.

Output display device – The quality of the output signal will depend
largely upon the type and quality of display device used. For instance,
some video projectors just look better than others.

Distance between the Scan Converter and the display device –
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 (coax-type) VGA cables. Line
amplifiers may also be necessary.

Output connection cables – Low quality cables are susceptible to
interference. They degrade signal quality due to poor matching and
cause elevated noise levels. Therefore, cables should be of the best
quality. Coax-type computer cables are recommended because of
their superior internal shielding characteristics.

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.
