Troubleshooting

Regardless of manufacturer or product, the majority of installation 
difficulties can typically be attributed to communication problems 
between devices or when high bandwidth transmissions are attempted 
with insufficient cable/connections. Should you find yourself in such a 
situation, we have drawn up the following checklist of general issues 
and causes that should help you shoot your way out of trouble without 
seeking further assistance. 

No or poor quality picture? 

     Device Connection - Are you connected and powered? Double check 
all HDMI and 5v power connections are firmly inserted into correct ports 
and that all devices are powered.

     Cable length – Your signal could be struggling to transmit over the 
length of your HDMI cable? If possible, try using a shorter HDMI cable.

     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.
 
     Resolution - 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 and make sure the signal is being 
successfully transmitted the full length of your HDMI cable. 

     Picture ‘snow’ / HD ‘noise’ – signifies a failure to fully establish a signal 
and can often be caused by excessive cable lengths. Try swapping or 
shortening your HDMI cable – if the problem continues on the same 
output, turn off all equipment and swap your signal carrying cables at 
both ends. 

     Cable quality and condition – HDMI cable/connectors can be easily 
damaged and the quality of material can vary, especially in lower price 
brackets. Successful transmission of video, audio and control can all be 
affected by cable and termination quality. Always use good quality leads 
and cables. Should transmission problems be experienced, try swapping 
cables/leads for those already working to see if this improves your image 
to identify cable issue as source of problem. 

     Blu-Ray, 3D - is the equipment used 3D enabled/ compatible? Is a 3D 
disc being played in a 3D enabled Blu-ray player or through a compatible 
AV receiver?  Are resolutions between source and display compatible with 
adequate cable bandwidth for the larger 3D transmissions?

See full user manual for further troubleshooting and general FAQ

     4K - Are you trying to pass a 4K signal? Ensure connected devices are 
4K enabled, correctly configured and outputting compatible transmissions
 
- 4K: 3840 (UHD) or 4096 (DCI) 2160 @ 30Hz with chroma (colour) 
subsampling rate of 4:2:2
- 1080p: 1920x1080p, 60Hz (if problems are experienced at 60Hz, try 
lowering to 50Hz) 

Safety Recommendations:

 

     Do not expose this apparatus to any form of moisture, including the 
placement of anything containing liquids on the unit. 

     To prevent risk of electric shock or fire hazard, ensure apparatus is
