So - frustratingly I am still having issues with the white flashes (and occasionally not even being able to get the K menu up on the screen to select a movie to watch.) I am at a loss as to what I can do at this point. The annoying thing is it doesn't happen all the time. I have managed to watch entire HDR movies without issues. And the next day, the white flashes begin, and I can't get the menu up without having to switch to a different HDMI port (Apple TV or something else) and then back to K, and it comes back. Here's the full breakdown of events:
All this started when I threw out a failing Yamaha AV receiver that I upgraded to a new Onkyo TX-NR6050. Here's the equipment I am using:
JVC DLA-NX7 projector
Onkyo TX-NR6050
Strato + Terra
There is a new HDMI cable running from the projector to the AV Receiver. I've also tried different HDMIs connecting the Strato to the AV Receiver, and the problems persist. The Onkyo is set to 4K Enhanced.
I have upgraded firmware on the AV Receiver and the Projector.
I'm attaching screenshots of the settings on the Strato, if anyone sees anything that needs to be fixed.
It's possible I got a bum Onkyo receiver, I guess. It's new out of a box, but could be damaged. I dunno anymore. I'm a total loss.
