Generally, the majority of HD distribution installation
issues are either caused by minor connection
errors, communication problems between devices,
or when the transmission of high signal bandwidth
is attempted using insufficient cable. Should you
encounter any technical difficulties when installing
and configuring the matrix, we are confident
solutions can be found by working through the
following troubleshooting checklist before seeking
alternative technical support.
No Picture or poor quality picture
1) Power
– are your HDBaseT transmitter or display
receiver baluns powered both ends? Transmitters and
receivers should have their own power source i.e. the 5v
power adaptors included with your baluns.
Are all sources definitely powered and firmly connected?
2)
If possible, always use test equipment prior to
installation and to troubleshoot any problems.
3) Distance
– Is your cable too long for the signal to be
transmitted effectively? HDBaseT allows transmission of
1080p up to 100m (328ft) so make sure you cable
distance matches your requirements and is well within the
maximum transmission distance of the signal.
Note:
If you are approaching the limits of the transmission
capabilities, you will need to use an additional WyreStorm
Extender set for the signal to transmit effectively.
4) Cable joins?
Joins in your cable run can impact on
signal strength, resulting in reduced transmission that
may manifest itself in poor picture quality or a complete
lack of picture
.
5) Signal Reduction
– Are you using stranded patch
leads as interconnects between patch panels or
wall outlets? Such use reduces signal strength – we
recommend solid core straight through connections to be
used wherever possible.
6) Resolution
– If you reduce the resolution of the
source, do you get a picture? If so, this suggests a
discrepancy between source and display resolution or a
bandwidth capacity issue with your cable.
Check that your inputs and outputs share the same
resolution and that the signal is being successfully
transmitted along your cable run.
7) Correct connection
– It may seem obvious but
double check all UTP, HDMI, power and IR cables are
connected to the correct ports.
Note: Even a fraction off can be the difference between
a perfect picture and a blank screen. Double check all
connections are firmly made in the correct ports.
8) Cable wired to 568B standard?
Is your cable wired
and terminated correctly and are those terminations
connected to the correct ports?
9) Electrical interference
– HDBaseT is less susceptible
to interference compared to regular transmissions but
the location of cables and devices should be considered
- could any form of interference be generated? If so,
attempt to remove the source of electrical interference
or move the cable run to decrease the effects of the
interference.
10) Do you get a picture if you connect the source
directly to the display?
If not then the problem could lie
with the input or output device rather than the means of
distribution i.e. the cable or matrix itself.
11) HDMI lead condition and quality
– HDMI cables
and connectors are delicate and can be damaged much
easier than component or coax cable. Furthermore,
lead quality varies dramatically, particularly in lower price
brackets. Swap your HDMI or VGA leads and check
operation – damage to or quality of your leads could be
the problem. If in doubt, swap them over. Always take
care inserting and extracting your cables from ports so as
not to damage the connectors or ports.
12) Picture snow/HD ‘noise’
– represents a poorly
established signal that may be caused by poor quality
terminations or excessive cable lengths. Try swapping the
display adaptors from a location you know is functioning
properly or swapping the outputs of the matrix switch
used.
If the problem remains on the same screen this may be
caused by a connection problem between matrix and
display – turn off all equipment and swap the signal
carrying cables at both ends to ascertain if the cable or
termination is at fault.
13) Blu-ray: Deep Colour
– make sure Deep Colour is
turned on in your Blu-ray settings and displays.
