SW1-SW4
for EDID/Audio
Note:
1. If the HDTV shows video but without audio, please try to
set audio mode to stereo.
2. Factory default setting of [SW1]-[SW4] is pin 1 at OFF ( ) &
pin 2 at OFF ( ) for 1080p with surround sound audio.
3. If you encounter any unsolved audio/video output
problem during system installation, please turn any
[SW1]-[SW4] to pin 1 at OFF ( ) & pin 2 at ON ( ) for
safe mode to enforce the most compatible 720p stereo
output 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.
4. 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.
5. To learn the EDID of HDMI display for respective HDMI source
devices, please see the [EDID Learning] section in the next
