3.7 Troubleshooting Notes
•
Check that both the Transmitter and Receiver have power. The green LED
on the Cat 6 port should be lit.
•
Check that all cables are connected to the correct input and output ports.
Secure the power cable with the locking ring.
•
Directly connect the HDMI source equipment to each display to test for
compatibility.
•
Test the Cat 6 cable with a network tester.
•
Try both EDID settings, test with only 1 display (local and extended).
•
Test with a different display for compatibility issues.
•
Check that the correct video input source and output display is selected.
•
Check the audio output settings from the source device or computer.
•
Test each HDMI cable by connecting it with other equipment.
•
Recommended maximum total HDMI cable distance In/Out is 15/15ft (4K)
and 25/25ft (HD).
•
Connecting an HDMI cable with a coupler or wall plate may degrade the
signal transmission.
•
Place the Extender away from fluorescent lighting or equipment that gener-
ates electrical noise.
•
A 'Not Supported' error message may indicate that the connected equip-
ment does not support HDCP (or more than 2 outputs) for viewing content-
protected video.
•
Check that the IR window on the source equipment is not blocked. The IR
cables require line-of-sight. Test at a closer range, some IR remotes trans-
mit a weaker signal.
•
Wait 10 seconds for a handshake signal when connecting a computer.
•
Plug and re-plug the HDMI cable.
•
Reboot the video source and output displays.
