- Check if the corresponding input source has been switched to the corresponding output port.
- Check your HDMI cables, or use new cables.
- Try restarting the matrix switch to check if it helps.
- Check if your display device supports HDCP.
- Try connecting the source to the display device directly, without using the matrix switch. Then check if there is any video output.
- Try connecting the source to the display device directly, without using the matrix switch. Then check if you set “Dolby Vision”.
- Log in to the matrix switch’s web interface, and set the input’s EDID mode to copy the corresponding output’s EDID.
- Check if the corresponding HDMI output port is outputting sound. If not, you need to check if there is any sound transmitted from the input source.
- If there is sound from the HDMI output port, try setting the corresponding input source’s audio format to PCM or DD 5.1.
- Check if the battery has run out of power.
- Check if the battery is installed correctly and on the right position.
- When you use the remote controller, it needs to be directly facing the IR receiving window on the front panel of the matrix switch, or directly facing the head of IR receiver cable.
- Check if the connection method of the RS232 cable between the matrix switch and the control PC/system is correct. It should be “TX-RX, RX-TX, GND-GND”.
- Ensure you set the correct parameters for the RS232 port. You can refer to the API command guide on our site.
- Check if you can add the terminators “CR”and “NL” in the command sender.
- Try restarting the matrix switch to check if you can receive restarting feedback from the device. In this way, you can check if the RS232 settings are correct.
- Ensure you have inputted the correct command.
- Try obtaining the correct IP address of the matrix switch via your router or software tool.
- Modify your PC’s firewall settings to allow the browser to access the matrix switch’s IP address.
- If the correct IP address cannot be obtained, try restoring the matrix switch to factory settings through RS232 commands, then try logging in again.
