Hi Gary_Berry: Thank you very much for contacting the Intel® Graphics communities. We are sorry to hear there is a video problem with your computer.
In order to provide the most accurate response, we will do further research on this matter, as soon as I get any updates I will post all the details on this thread.
Any further questions, please let me know.
Hello. Are there are updates? I'm stuck at this point. I can't downgrade the Intel ME firmware to the original version (126.96.36.19914) and get error 8805, which basically says the SVN doesn't allow downgrades. Reinstalling firmware, graphics drivers, ME drivers (188.8.131.522), etc. None of it works. I'm assuming the Protected Audio Video Path (PAVP) is either broken somehow, or Cyberlink is misinterpreting data it's receiving.
I do have one last ace in the hole. I did find MEInfo and was able to run it. I'll see if I can find someone who hasn't upgraded their motherboard and can get them to report back. In any event, here's what I'm seeing. Maybe this will help an engineer troubleshoot where the failure is occurring. Nothing jumps out at me but I don't totally understand ME.

Okay. After doing a lot of research elsewhere - Intel, ASRock, and Cyberlink all continue to ignore me - it looks like the problem might have to do with the ME firmware. There's an entry for "LSPCON Display Port 1" (description: "The setting determines which port for LSPCON will be connected to the HDCP 2.2 bridge adapter Display 1"). When I run MEInfo, no LSPCON ports are listed. I'm hoping to hear back from somebody today who has a functional system and can let me know if a port is listed. If so, that's probably the issue. At that point, I'm going to have to either resort to hardcore trickery in order to reprogram the ME firmware or hope that somebody from Intel or ASRock will take pity on me and offer me a reasonable way to fix the problem.
In the meantime, I'd really appreciate it if somebody from Intel could assist me. I put a lot of money into specialized hardware so that I can play UHD discs, only to have it all blow up in my face when I try to apply a fix recommended both by Intel and ASRock. This is unacceptable, quite frankly.
Hello. Just FYI, the problem has been solved. A new BIOS had what appeared to be a slightly modified version of ME firmware 188.8.131.5225. Around the time it was released, ASRock's INTEL-SA-00086 mitigation site was updated to imply that Z370 board owners couldn't rely on the generic ME firmware. I guess that, unlike Z170 and Z270 versions of the board I own (I corresponded with a Z170 owner who apparently updated ME firmware willy-nilly and had no HDCP 2.2 problems), the firmware somehow has to be tied to the board via HDCP licensing and such. I don't like this, as it implies that future fixes can't be applied without breaking HDCP 2.2 once ASRock stops supporting my board. Oh well. That's a battle for another day. For now, I'm good.
