Well it appears the problem is with the Anthem AVR. I have a Anthem AVM60 pre-amp also, I haven't installed it yet because I am waiting for the AMP I chose to go along with it. For grins I tried putting it in the chain with the Projector and the Dell and no problems.

Have you set your Anthem AVR to 'through' (or similar) to ensure you're bypassing any video processing? I had issues with my Pi2/3 with Onkyo NR636, which was processing the video, and as a result, messing up EDID data, even when set to 'through'. Wondering if something similar is going on w/yours. But, maybe yours will actually do what it's supposed to w/sending signal straight through.

Yeah I tried it both ways. Neither worked. Made sure the Anthem Receiver was at the latest firmware too. Strange thing is that the Anthem AVM60 pre-amp works fine.

I guess in the end it doesn't really matter, I am selling the Anthem MRX710 anyway.
