Re: Can I connect Roku Premiere+ to Denon AVR-S930H WITHOUT TV ARC?
I don't have a Denon AVR, but I have no issues getting video/audio from my Ultra through a Yamaha AVR. My Roku settings are all on auto, and the Yamaha is set to do video passthough. I don't want/need my AVR to scale any video that passes through it. Perhaps your Denon is attempting to scale the video (and obviously failing).
