turn any [SW1]-[SW4] to pin-1 at ON []& pin-2 at OFF []for safe mode to select the system
EDID up to 720p(1080i) video and stereo audio for system check. However, the safe mode
cannot be initiated if your HDMI source is set to enforce 1080p output. In this case, please
reconfigure your HDMI source to all resolution output for troubleshooting.
4Bypass 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.

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 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.
Note
SW1-SW4 Pin#1 and Pin#2 must be set “ON” & “ON” for EDID Learning Mode

EDID Learning –
for learning EDID from the receiver

Method: Manually connect HDMI displays to HDMI input ports
1. Power up the matrix master unit. Connect the HDMI display that its EDID needs to be learned to
any of the HDMI INPUT1 - INPUT4 port where your source device has trouble to show the
picture normally.
2. To learn the display’s EDID for source device connected to respective HDMI INPUT1 - INPUT4
port, pull both pins of respective DIP switch SW1 - SW4 up-and-down to stay at ON [ ] - ON [ ]
and wait for about 5 seconds to complete the EDID learning process. You DON’T NEED to pull up
the DIP switch again unless you want to learn another display’s EDID by pulling both DIP switch
pin-1 & pin-2 of SW1 - SW4 up-and-down one more time.
3. Repeat step1 & step2 if you want to learn the EDID of this HDMI display on any other HDMI
input ports that have same trouble playing the audio/video properly.
