I had 3 meter cable between each but for some reason running ATV @ SDR 4K 50Hz 4:4:4 caused occasionally flashes on the screen and sudden short black screens (once maybe every 5 minutes) but that happened only when playing SDR content at mention rate. When playing DV from Netflix @ 24p 4K it worked. Interesting thing was when I ran check HDMI connection in ATV when it was turned on within say 15 minutes it said "connections looks better" but once drop outs happened or it was on for longer it would report some problems maintaining stable connection in that test. Sounds odd how warming up would make any difference in case it was a cable issue?? (or does it somehow "overheat" or strain some error correction circuits causing that).
Since I haven't noticed issues with my UHD BD player in the same setup I decided to try new cable between ATV and RX-A1080 so I replaced that 3 meter cable with 2 meter cable (I happened to have one in unopened retail box at home so I gave it a try). Now it seems I did not notice drop outs or screen going black occasionally when playing 4K SDR 50Hz 4:4:4 material and also check HDMI connection test in ATV gave me "connection looks better" even I had ATV on for like 3 hours.
Anyway, I'm wondering about that test results, that isn't it supposed to say "connection looks good" or something like that instead of "connection looks better", or is that best it can say??
Or is there some limitation with that combination or does it imply I don't have selected Dolby Vision as default format?
I have match dynamic range and frame rate, so I can display 24p, Dolby Vision and HDR when selected title supports it. I rather not keep HDR or DV as default for ATV as it is "burning" my screen for no reason.
All the HDMI cables are only High Speed with Ethernet but they should be decent ones.
Bump. Just wondering if others get Apple TV report HDMI good instead of better doing this test?
I haven't seen it glitching lately after above mentioned one cable replacement but the Apple TV cable test still says connection look better. Shouldn't is say connection looks good? Also when I try test Dolby Vision in the menu it says it has problem maintaining signal even it appears to be working fine when I just manually put it in DV mode?!?!
So I'm just wondering whether I should try getting even better cables to get that test say good, but is there any other reason as it currently seems to be working just fine as it is?

This usually isn’t a problem if you have adequate ventilation around the receiver. Ive owned many higher end Yamaha receivers over many years and have alway run them with 4 ohm speakers while the receivers were set to 8 ohm setting. If your change the receivers settings to 4 ohms, you will lose power output but it will run cooler. It’s an FCC thing.
Do you mean it is completely safe and would be even better to leave receiver at 8 ohms even speakers are under 8 ohms? I have 6 x 6 ohm and 1 x 4 ohm speakers connected and I changed receiver to 6 ohms setting. I would get more power out of it if I just put it back to 8 ohms?
My receiver is in a shelf with front side fully open and few holes in the back for the cables and above the receiver is about 6 inch free space between next shelf, so it is relatively well ventilated even it does feel rather warm after using it for couple hours depending on the volume level.

Is there a big difference features and sound wise between the 1080 and 3080 if I were to use pre outs since I won't be using the amp portion of the receiver? Ideally I'd to get the 5200 pre/processor, but it's just too expensive. I figured I can get into the 4k world by getting the RX-A1080 if I'm not sacrificing much.
Not sure that this helps but I upgraded from 1800 to 1080 mostly for 4k I also need now and I've been happy but I'm using receivers build in amplifier. For me 1080 sounds a bit "beefier" (I like that) than 1800.
I was initially waiting for 2020 models but when I saw how ugly they looked in the leaked photos I ran to the shop when I could still get 80 series model that has looks what I prefer.
