your HDMI source is set to enforce 1080p output. In this case, please reconfigure your HDMI
source to all resolution output for troubleshooting.

Bypass means the matrix will maintain playing the original format of HDMI signals in video
and perhaps audio. By setting at this mode, the users may encounter compatibility issue
among different kinds of HDMI sources and displays. If you cannot get the audio and/or
video output normally at the system installation, please change the DIP switch setting to
default mode or even safe mode to verify the functionality of the device.

for 20 seconds. The EDID learning procedure will be finished. If you want to learn the EDID
from another HDTV, you must set Pin#1 at OFF[] first and repeat this procedure.
