EDID LEARNING
The EDID learning function is only necessary whenever you encounter any display on the HDMI
output port that cannot play audio and video properly. Because the HDMI sources and displays
may have various level of capability in playing audio and video, the general principle is that the
source will output the lowest standards in terms of audio format and video resolutions to be
commonly acceptable among all HDMI displays. In this case, a 720p stereo HDMI signal output
would be probably the safest choice. Nevertheless, the user can 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 is a method to do EDID Learning as below:
Software Control: Please refer to the Operation Approach\ Method B: Software Control
