TROUBLESHOOTING
Should you encounter installation difficulties or issues with device
communication, the following checklist of common issues and causes
should help resolve your issues.
No or poor picture quality:
• Connected and powered? Double check all HDMI, Ethernet and power cables
are firmly connected into the correct ports and all devices are correctly
powered.
• Cable length? Are you approaching the maximum distance of the cable (70m
for 1080p or 40m for 4K UltraHD)? If so, adjust the picture quality or try using
an additional extender kit to go further distance. Cables bundled together
may cause cross talk and further degrade signal quality.
• Signal strength? The use of cable joins, stranded patch panels, wall outlets
and stranded patch leads as interconnects between them, can significantly
reduce signal strength. Use solid core straight through connections wherever
possible.
• If you reduce the resolution of the source do you get a picture? If so, this
suggests a conflicting resolution between source and display or a bandwidth
capacity issue with your cable. Check all inputs and outputs share the same
resolution capabilities.
• Picture ‘snow’ / HD ‘noise’ signifies a failure to fully establish a signal and
can often be caused by poorly terminated RJ45 connectors or excess cable
lengths. Ensure your cable is correctly wired to 568B standards.
• Cable quality and condition - HDMI cable/connectors can easily be damaged
and the quality of material can vary, Always use good quality leads and cables
and try swapping cables that are known to be working into the solution to see
if this improves your image.
IR control:
• Are the IR emitters and receivers correctly positioned to allow infrared signals
to be transmitted and received through the extender kit? Emitters should be
fixed firmly over infrared sensors of sources. Receivers should be attached to
displays ensuring a clear line of sight to the remote control used to operate.
• Is your remote control powered and sending a signal? As IR is invisible to the
naked eye, check your remote is transmitting a signal by viewing the remote
handset sensor thought a digital camera/camera phone. The sensor should
flash when a button on the handset is held down.
• IR signal dropout can be experienced due to exterior emissions of infrared
radiation. Ensure emitters and receivers are away from direct sunlight.
Halogen lighting and plasma screens may also interfere with IR signal.
