Dear AVS Community, I first wanted to thank everyone that is involved in this forum in contributing your time and knowledge to this wonderful little home. As an outsider that had very little experience with home A/V please never forget how invaluable your resources and knowledge are to those looking to get started for the first time. I couldn't have done my build without you!
That being said, I have scoured high and low and am stumped :/
Here is my gear: RX-A3050 11.1 setup, with rear presence powered using an external amp mounted in a custom rack installed in-wall. Everything through a power filter with inputs from the Samsung UHD BD, and my PC with a 980TI. Output goes to my wall mounted OLED 65 E6P. Wires were Monster Black Plat XP's (I found discounted 80% at a rural isolated Best Buy here in Washington-never would have paid full price ha!) and cables are BlueRigger high speed CL3 HDMI. All in-wall to Pioneer Elite Atmos speakers and a HSU VTF3 MK5 sub. Took me three years to save for and a whole year to install (thanks to your help and recommendations.)
Everything has worked gloriously for the past year or so-ish. Movies are flawless, sound from concerts is breathtaking and gaming from my Win10 PC was brilliant in [email protected]
with 4:4:4 Chroma.
What makes me look like a total loser is that I hadn't ever updated the Yamaha's firmware from the stock config which was 1.66 or 1.68 or something. I didn't have any DTS-X titles and figured I would get around to it when I actually needed it.
Which leads to my current disaster. I updated to 1.89 the other day to play Ex-Machina (which was AMAZE btw) and everything went smoothly, kind of. I did a physical USB update as over wifi made me a little weary. The first time it error'ed out about halfway through. In a panic I didn't capture what it said and pulled the power so I could initiate a forced re-flash upon plugging it back in, which I did, and everything went perfect the second time. Power cycled and it came back up flawlessly in 1.89. Movie was brilliant.
Yesterday afternoon I went to use my PC to preview a presentation on my oled and low and behold, I can no longer get the receiver to recognize a [email protected]
4:4:4 output. It had worked perfectly a couple days before. It will do [email protected]
4:4:4 but not 60. It will do a [email protected]
4:2:2. I was able to run another longer 10m BlueRigger cable (an extra I had thank god) across the room and manually plug it in to the OLED directly from my PC so I wasn't hamstrung the rest of the day and bam [email protected]
4:4:4. (Which mind you is entirely in the spec of the TV, graphics card, OS and hdmi cable.) But no matter what I do, my 3050 will no longer accept a 4K60 4:4:4 input.
I tried reflashing 1.89. Reflashing with all of the hdmi's unplugged. Backed up my settings through the web interface and reinitialized the whole receiver. Reinitialized and then restored. I moved the PC right next to the receiver and tried a six foot BlueRigger to make sure it wasn't a length issue. Rebooted all devices, unplugged, re-plugged, danced on my head. No drivers have been changed on my PC and the only change was the 1.89 Yamaha firmware.
In my reading I see that firmware 1.77 included updates to the HDMI outs to enable HDMI 2.0a support. Could updating from the receivers stock HDMI 2.0 to 2.0a have disabled the cables I am using? (I am deducing it must be the cables.) Is it possible the error in question during my initial flashing had to do with the HDMI portion? I feel like I read somewhere during the 1.77 release that someone mentioned to make sure and not have anything plugged into the HDMI's when you go to update them to 2.0a. (Which I didn't do initially when I did the 1.89 because it mentioned nothing about doing so in the instructions.) Do the HDMI ports have their own separate firmware rom? If they do, is it possible that during the initial flashing when things error'ed out that it never completed going to 2.0a and it has left things in a limbo state? If it's not the cables could the receiver have been messed up and simply won't do high-speed 4K60 444 anymore? That seems illogical based on the fact everything else works including outpouring 4K UHD HDR from the Samsung UHD player.
I am not able to just get new HDMI cables without a tremendous amount of effort to re-open up all the walls and re-string the HDMI's. It took months to complete that part.
How is it possible that everything worked flawlessly for a year and now the receiver doesn't like the high speed cables I'm using after a firmware flash? I am at my wits end, this is a complete game breaker for me. Is it possible to downgrade back to something before 1.77? I'd rather forgo DTS-X in exchange for a working PC input.
Had anyone ever even heard of cables being rejected after a firmware update? This is nuts.
Help me AVS you're my only hope!
