11.Common troubleshooting
Q: Why no image displayed on screen?
A: Please check if the switcher output resolution is set to 4K and the displayer doesn’t
support 4K. If like this, please long press front Resolution button to change the output
resolution to 1080p or some others
Q: Why no audio heard?
A: About 4 possibilities
a. Because audio selection is separately from video selection, please check if the audio
selection is what your wanted source. Suggest select WIN1 if no special requirement
b. Please check if Audio-Mute is enabled via OSD menu or RS232 command
c. Please check Audio Volume value via OSD menu or RS232 command
d. Please check if the audio format is compressed format and your audio receiver
doesn’t support this format
Q: Why no feedback when adjust audio volume VOL+ or VOL-
A: It should because the audio source is non-LPCM format (such as AC3, DTS 5.1).
User can’t change audio volume with the switcher when non-LPCM format audio
Q: Why no response when control the switcher with RS232 cable
A: Please find the exact RS232 baud rate value via the OSD menu
