EDID
EDID management allows for EDID learning or to pre-set an EDID to encourage a “handshake” between the
display and source.
The EDID learning function is only necessary whenever any display on the HDMI output port is not outputting
audio and video properly. Because the HDMI source devices and displays may have various level of capability in
playing audio and video, the general principle is that the source device will output the lowest standards in audio
format and video resolutions to be acceptable among all HDMI displays connected. In this case, a 720p stereo
HDMI signal output would be probably the safest choice. The EDID function can also force the matrix to learn
the EDID of the lowest capable HDMI display among others to make sure all displays are capable to play the
HDMI signals normally.
There are two methods for EDID Learning as shown below:
