2.6 Maximising the video quality

The SmartView XPro 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 SmartView XPro installation we recommend the following:

Use the shortest possible video cables between your devices. High quality two metre long cables such as the Adder 3-in-1 combination cable 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

mmin 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 SmartViews 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 AdderLink extender.
