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 
Video Scaler.

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.  

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) VGA cables and Premium DVI 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.
