1.3 Getting the Best Results
There are many factors affecting the quality of results when converting video
signals. Some basic precautions will ensure the best possible performance from
this product.
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 Video 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 and premium DVI Cables such as DVIGear’s Super High
Resolution™ cables. In some applications the use of digital repeaters or extenders
may also be necessary.
Output Connection Cables – Low quality cables are susceptible to interference.
They degrade signal quality due to poor impedance 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.
