EDID LEARNING
The EDID learning function is only necessary whenever you encounter any display connected to
the HDMI
™ output port that cannot play 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 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 by performing the procedures stated
below.
