Strato with 2020 D&M receiver?

Hi. I've got an install with a Strato connected to a new Marantz SR7015 and Sony 950H TV. Running through the Marantz I get flashing white screen periodically when watching 4K HDR content. Might not happen until 5-10 minutes into a movie, but then once it happens, it regularly happens every 10 seconds or so. When I bypass the Marantz and go straight to the Sony, no flashing. I've tried multiple inputs on the Marantz, and it still happens. Lowered bandwidth from 18 Gbps to 13.5 Gbps and that has helped but not eliminated the problem. Apparently the new 2020 D&M receivers are all using a new HDMI board/chipset (with an 8K capable in and out), and I'm wondering if anyone else has a Strato and a new D&M product that has this...? (Unfortunately, directly connecting the Strato to the TV isn't a long-term fix as my client ultimately wants to add a 4K PJ to the system, so I'll need to run it all through the receiver to serve both TV and PJ.) Thanks for any thoughts or suggestions!

Haven’t seen this but one weird thing I had previously on a Denon receiver, was that if you can, put the Strato into the closet port to the output and see if you experience the same.

Thanks for the suggest! On the 7015, the closest connection to the monitor outputs is HDMI 7 (8K IN). I've tried both it and HDMI 6 and get the same issues. I should have added earlier that I've traded numerous emails with Rusty and also sent K engineering multiple EDID logs and files and they don't see anything amiss. Feels like a case of three things working OK separately, but not liking when the band is all together...

Okay, and assuming you have also tried the non eARC output as well? I hate HDMI for these exact reasons in very odd behaviour with no diagnostic information.

My AV7705 might be the prior gen boards but that is working perfectly with a new Strato. I do know there are newer 8K HDMI cables coming from AudioQuest etc.. That might be worth trying....lot's of HDMI board issues from what I am hearing in the great AVR shortage of 2020.

I haven't tried the non-ARC (the primary Monitor) output; It does have a Monitor2 and a Zone2 (not sure Zone2 supports 4K HDR, but probably...) I could check that. I've tried different inputs on the Sony TV, including HDMI 1, 2, and 3(eARC).

Yeah, I personally have an 8805 with 0 issues, but those are all last gen boards... Trying to determine if I just have a singleton bad 7015 OR if the whole line has some glitch...
