Getting the Best Results
Many factors influence the quality and reliability of HDMI signal distribution
installations The following are the main factors to consider, and basic precautions
that will ensure the best possible performance
●
SYS-RST for Source Switching - If the source device will be switched often
during operation, as in the case of an HDMI switch connected at the head end
of the distribution system, set the SYS-RST switch to ON (SYS) This setting
prevents the 1398D from interrupting video and audio transmission to re-learn
EDID settings each time the source is switched, or a TV is hot-plugged to the
distribution system
●
Resolution tracking - Set the source to output the best resolution that all
TVs are capable of displaying. Utilize the following instructions to ensure that
all TVs connected to the DA receive video signal. If the TVs have a wide
range of resolution capabilities, the highest resolution sets may be shown at
a lower resolution
●
Source resolution and video/sound quality - Sources, such as satellite
receivers or cable boxes can output at low resolutions or deliver compressed
video material that may yield poor results Consider the source when planning
and troubleshooting your system
●
Output display devices - The quality of the video image depends upon the
type and quality of the HDMI display devices used. The device with the lowest
resolution will be the reference standard for the rest of the HDMI displays
connected to the DA.
●
Distance between the DA source and the displays - Use the shortest
cables possible, but premium certified high speed cables and advanced
HDMI extenders may be necessary for the longest runs.
●
Connection cables - HDMI cable design and quality are extremely important
in long cable runs where capacitance can severely degrade performance Use
premium certified high speed cables designed to handle 4K resolutions and 3D;
low quality cables are susceptible to interference. Always use good strain relief
methods to prevent cables from becoming loose over time
●
Interference from nearby electrical devices - RF emission can have an
adverse effect on signal quality. For example, older computer monitors often
emit very high electromagnetic fields that can interfere with the performance of
nearby video equipment.
