EDID
The EDID switch allows for EDID learning or to pre-set an EDID to encourage a “handshake” between the
display and source.
The EDID dial helps out in forcing or encouraging a handshake between the source and display with the
extender in between. If you are not receiving a video/audio signal with the extender in place, verify the
category cable isn’t the issue by connecting a pre-terminated jumper or patch cable. Also verify the source is
actually sending a signal by connecting straight to the display via HDMI.
The default EDID setting is set at 0, which should work with most combinations, however if you are
encountering no HDMI signal, then an adjustment on the EDID dial can be attempted.
Manual EDID Learning Mode
See below for EDID table, when any of the EDID position selections are made,
the Transmitter will set a fixed EDID to the source. To make this adjustment,
follow the below steps while every component is TURNED ON.
1. Unplug the POWER SUPPLY and HDMI cable from the Transmitting unit only
2. Adjust the EDID dial to the desired setting
3. Connect the Power Supply
4. Connect the HDMI cable
At this point the EDID you’ve selected is now sent to the source, check the display for video/audio signals.
Auto EDID Learning Mode
Attention: Confirm the extender is displaying audio and video correctly after each selection. Each time the
EDID is modified, the transmitter must be unplugged from power and HDMI, and then power plugged back in
first, followed by the HDMI (see above for manual EDID learning).
