2.6 Maximising the video quality 
 
The LINDY CPU Switch Dual MP supports very high bandwidth video signals and 
resolutions up to 1900 x 1440 pixels. It regenerates the video signals using wideband 
amplifiers in order to minimise any loss of video quality. All video cables introduce 
distortion onto the video signal. For short cables this is minimal but for longer cables 
the loss of quality can start to become noticeable particularly at higher video 
resolutions. To maximise the video quality of your LINDY CPU Switch Dual MP 
installation we recommend the following:
 
 
  
Use the shortest possible video cables between your devices. High quality two 
metre long cables will give excellent results. 
 
  
Avoid using cables with 15-pin D-type connectors that are not specifically 
designed to carry video signals - you will see a picture but the quality will be truly 
appalling with smudging, ghosting and loss of focus. Cables that are designed to 
carry video signals are constructed using three separate co-axial cores to carry the 
red, green and blue signals. These co-axial cores make the cable thick like the cable 
that you see coming out of the back of a monitor. Typically this cable will be 8.5 to 9 
mm in diameter. If your cable is thin (say 6mm in diameter) or does not look like the 
cable you would expect to see coming out of a monitor then it may well be an 
unsuitable 'data' cable. Such cables are only suitable for very low resolution DOS-
style screens. 
 
  
Where possible use a single cable of the correct length rather than multiple 
extension cables. If you must use an extension cable then make sure that it is a 
cable that is specifically designed to carry video signals. 
 
  
When cascading LINDY CPU Switches use the shortest possible cables between 
units. Structure the installation so that the maximum cable run between computers 
and KVMs is minimised. If possible keep this distance to below 30 metres (100 feet). 
 
  
For longer distances use the LINDY extender.
