Your signal connection for HDMI is: PI -> some random AV receiver -> some random beamer (as you've provided zero details).
The Pi nows nothing about yoir beamer, he only cares about the AV receiver.
Connect the receiver+beamer to your Pi, remove the uSD, power up and take a picture of the image you see.
You should see a boot diagnostics screen https://www.raspberrypi.com/documentati ... berry-pi-4
Post the picture on the forum (resizing it may be needed).
