Thanks a lot for this very useful test.Update: I was able to borrow a Yamaha TSR 7850 and a BenQ HT3550, working combination, and test my Yamaha RX V6A and Optoma Cinemax P2. In doing so I found that the RX V6A worked with the BenQ 3550 and the TSR 7850 worked with the Optoma P2. It was only when the RX V6A and the Optoma P2 were put together that there was an issue of grabbing the input and flashing static or recognizing any input.
Since then I have gotten a Marantz SR5014 (2019 Model) and everything is working great, only a couple days running it. Whether it is the 2020 model AVR that is the issue or if it is that the Optoma P2 is not fully compatible with the 2020 model AVRs or not I am not sure since the RX V6A worked with the BenQ 3550. Hope this helps
Does anyone know if Denon avr-x3600h (normally it's HDMI 2.0) + Optoma P2 work ?
