Been fighting an apparent HDMI HDCP issue for awhile.

Roku Ultra (current version) --> Marantz Cinema 50 --> Epson 5040UB Projector [Monitor 2] and TCL QM8k [Monitor 1]

No issues with E-ARC.

Isolated the issue to the Receiver when both video outputs are enabled, even if they aren't both in-use. Manually setting the output works.

If you search the interwebs, all they ever say is power cycling, cable replacement, and other standard layer 1 things. Receiver-specific guidance talks about upscaling, eliminating video processing, and manually setting HDCP version to 2.3.

Just throwing this out to the void in case others have similar #hometheater #hdcp #avr issues. Will see what Marantz says.

The thing I was looking for the other day would cost me almost (twice, for 8x8) as much as the storage did. So I guess I'll not be buying it. I feel like 773,50 Euro, (or 1541,05 Euro for the 8x8 version) is more than enough money to incentivise standing up from the desk and walking into the other room to occasionally plug the HDMI cable into a different port.

However here it is #HDMI matrix switch with WebUI, and #HDCP 2.2

I got HDCP errors on my AppleTV late last night. Most of the other issues I’d been experiencing were video output issues.

One recommended fix for this is to pull the power cord from your TV or screen so that it reboots rather than just enters standby mode.

I did that, left it unplugged for a few minutes, and also pulled the power cord from the AppleTV.

That fixed the HDCP errors. Fingers crossed it also fixes the other issues I’m seeing.

1st time that I actually got a #DisplayLink dock working mostly acceptably... after using a DP to HDMI converter cable to not use its singular HDMI port. So either the port is bad or #HDCP was being a pain in the rear-end. Fingers crossed that this will survive reboots... 🤞

(I know one thing: my next laptop will be equiped with USB4 or Thunderbolt. DL is a crutch. And before you ask: the screens' DP connectors are already in use by my PC.)

I just wanted to continue watching The Fall Guy, which I bought from Apple TV. But both on my PC and on my Samsung TV I get an HDCP error in the Apple TV app. What the hell???? The film was still running the day before yesterday!!! 📽️ 🍿

With this in mind: off to bed.

Leider teilweise zäh vorgetragen, aber Inhaltlich dennoch interessanter #38C3-Talk, wie 2010 der #HDCP #MasterKey für das #DRM der #HDMI-#Video-#Schnittstelle u.a. aus #NVIDIA-#GPU-Hardware/Firmware extrahiert wurde.

Am besten gefällt mir die Stelle, wie der NVIDIA-#Security-Prozessor beim Versuch falsch signierten Code zu starten die korrekte bzw. erwartete Signatur einfach in einem Register vergisst, so dass man die Operation nur mit dieser Signatur restarten muss. 🤦
