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
Video Scaler.
Output display device
– The quality of the output signal will depend
largely upon the type and quality of display device used.
Using Native Resolution –
It is always best to set the output
resolution of the scaler to the native resolution and refresh rate of the
display device. This allows our scaler to do most of the work, which
usually results in a superior picture.
Distance between the Video Scaler 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) cables or adding line
amplifiers.
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.
