Hi. My apologies if this is not the correct place to post this message. I figured it was the most relevant since it had to do with an HDMI handshake protocol (HDCP 2.2 in particular).
I recently installed a fix for INTEL-SA-00086. After installing the update supplied by my motherboard manufacturer, rebooting my PC, and confirming that the correct ME version was listed in the UEFI, I tried to watch an Ultra HD Blu-Ray disc. Playback failed. I saw an odd error message from PowerDVD and used Cyberlink's playback advisor to make sure everything was in line. Much to my surprise, it said that HDCP 2.2 was "not available." There's no reason I know of why this should be the case. To be safe, I reinstalled the latest Intel display driver. No dice. HDCP 2.2 is still marked as not being available.
I'm writing to seek further advisement. To be honest, my gut suspicion is that this is an ME issue. Before installing the ME fix, there had been some playback issues under certain circumstances. For example, when trying to watch UHD discs (and Netflix using various apps and browsers), the video would drop out every few seconds, like a handshake had failed and needed to be done again. Something about the ME fix might have been the fatal blow. To be clear, before the ME fix was installed, the new display driver had dropouts but I was able to play back UHD discs, even if the end result was essentially unwatchable.
As a troubleshooting step, I reinstalled my older display drivers. No luck. HDCP 2.2 was still broken. So, it's almost certainly an ME issue, unless the display drivers need some sort of update (or Cyberlink's software needs an update, which wouldn't surprise me at all).
Here's what I consider to be the relevant portion of my setup. There's other stuff but I don't think it's relevant.
