12.Common troubleshooting
Q: Why no image displayed on screen?
A: Please check if the switcher output resolution is set to 4K and 4K-AUTO setting is OFF.
If the setting like this and the displayer doesn’t support 4K, the issue should happened,
then please long press front Auto button to change the output resolution to
1080p and change 4K-AUTO to ON
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 your wanted source via OSD menu or RS232 command. 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 we set 3840x2160 output resolution, but the displayer shows 1080p input?
A: Please check if the 4K-AUTO setting is ON, If so, it should because your displayer
shows no 4K capability
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)
we can’t change audio volume with the switcher when non-LPCM format
Q: Why no response when control the switcher with RS232 cable
A: Please find the exact RS232 baud rate value via the OSD menu
Q: Why no response when control the switcher with TCP/IP?
A: Please check the IP address, NetPort, Baud rate setting. The switcher and your router
must be on the same network segment
