I am trying my best to get my Dune HD to work with my new Epson 6050/9400 projector. It works when I connect directly but not with my older Denon receiver, a avr 2311.

My blu-ray player AND my Xbox One X works when I connect through the receiver.
I have tried every resolution setting in the Dune but Epson always says "No signal" except for 576p. Everything above gets "No signal".

What is it with the Dune compared to my BD and Xbox?

I see the loading screen with my Epson when I start the Dune and I can see that the signal is progressive 1080p but when the Dune is loaded it disappears.

Please help me, you are my only hope (Star Wars reference)
