No signal on projector EH-TW6100W Wireless HD

  • I have an EH-TW6100W (e p s o n) projector which has a wireless transmitter that also acts as a switch for five input sources. One of them is my RPi 4 with LibreElec installed.

    The wireless transmitter has two output modes:

    1. output via HDMI to a television/screen (this works properly with Libreelec, no issues at all!)
    2. output signal via Wireless transmission to projector (as soon as selecting this -> no signal error, output seems to be disappeared)

    I already tried a few HDMI settings but nothing worked for me up until now. Is there anybody having the same issue?

    Interestingly, back in 2017, some asked a question somehow connected to this issue.

    Thanks in advance for your help!

    Merry Christmas to you all!
