Common Troubleshooting

Q: Why there is no image displayed on screen?
A: Please check if the switcher output resolution is set to 4K, and the 4K- AUTO setting is OFF.
If it is, and the displayer doesn’t support 4K, the issue should happened. Then please long press the AUTO button on the front panel to change the output resolution to 1080p and set 4K-AUTO to ON.

Q: Why there is no audio heard?
A: About 4 possibilities:

• Since audio selection is separately from video selection, please check if the audio selection is the required source via OSD menu or RS-232 command. It is recommended to select WIN1 if no special requirement.
• Please check if Audio-Mute is enabled via OSD menu or RS-232 command.
• Please check Audio Volume value via OSD menu or RS232 command.
• Please check if the audio format is compressed format and your audio receiver doesn’t support this format.

Q: Why does the displayer show 1080p input when the output resolution is set to 3840×2160?
A: Please check if the 4K-AUTO setting is ON. If so, it should because your displayer doesn’t support 4K.

Q: Why there is no feedback when adjusting audio volume (VOL+ or VOL-)?
A: It should because the audio source is in non-LPCM format (such as AC3, DTS 5.1).
we can’t change the volume of audio in non-LPCM format with the switcher.

Q: Why there is no response when controlling the switcher via RS-232 command?
A: Please find the exact RS-232 baud rate value via the OSD menu.

Q: Why there is no response when controlling the switcher via TCP/IP port?
A: Please check the IP address, NetPort, Baud rate setting. The switcher and your router must be in the same network segment.
