4.0 PLANNING A MATRIX SYSTEM
• Each display should be individually tested by connecting it directly to each
source to ensure basic compatibility before connecting them to a matrix. After
testing the sources with the displays, temporarily connect all of the sources
and displays to the matrix using short HDMI cables to verify compatibility and
function.
• Since all of the displays connected to a particular source will be receiving the
same video signal resolution and format (e.g. 1080p@60Hz) produced by
the source, make sure the source is set up to output the highest resolution
that all of the displays can accept. For instance, if one display can accept
a maximum input resolution of 720p, all of the sources are limited to 720p
output, and all displays will receive a maximum resolution of 720p. This
consideration is particularly important if the TVs have a wide range of
resolution capabilities because the highest resolution sets may not be allowed
to perform to their best advantage.
• HDMI cable lengths should be kept as short as possible. Use high quality
HDMI extenders (such as our Model 1391A) where cable lengths must exceed
15m. Use of high resolutions, refresh rate, or deep color may limit maximum
cable run length.

To the extent that high resolutions, refresh rate, or deep color are used, cable run length is
diminished. Use high quality HDMI cable extenders for long distance, high bandwidth applications.
