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.

SAFETY PRECAUTIONS

Please read all instructions before attempting to 

install or operate this equipment. 

Please keep the following in mind as you unpack 

and install this equipment:

• Always follow basic safety precautions to 

reduce the risk of fire, electrical shock and
