Okay, here is my system, then I will ask my question
Roku Ultra, Yamaha CXA-5100 pre amp, Yamaha MXA-5000 AMP, JVC RS620 projector, control 4 control system/remote Issue is ROKU will not "turn on" when starting up with ROKU as first source. I get blank 'no input" screen. The only way to get ROKU up and running is to switch sources, for example to Appl TV, and then back to ROKU and its up and running. We thought maybe it was an "auto detect" issue with display type in ROKU. I change the ROKU to default to 4K 60hz HDR, which is what auto detect is detecting, which is correct. This not only does not solve the problem, but when I go back into ROKU, it reverts back to auto detect. It will not save any settings and reverts back to auto detect. I replaced the ROKU with a brand new one last night, same issue, so clearly not a dysfunctional ROKU unit. I am able to play everything correctly with ROKU once its up and running, including appropriate 4K and HDR source material without issue.
would love some help on why display setting not storing and what may be preventing ROKU from starting up without having to switch input....My concern is a compatibility issue with either my Yamaha or my JVC projector. My installer of my system has similar setup with JVC and different pre amp, and they did not have issue.. so wondering if might be Yamaha?
