15. Troubleshooting
Should you encounter installation difficulties or issues with device communication, the
following checklist of common issues and causes should help resolve your issues. If
you continue to experience issues, please contact your place of purchase.
NO PICTURE 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,
40m for 4K) 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.
Pink or off-color picture? This could be caused by an invalid EDID or the source device
failing to read the EDID from the matrix. Try re-booting matrix and all source devices to
force the re-reading of the EDID.
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 to see if this improves your image.
