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 still remember the incredulity (and later confirmation) as the HDCP 1.4 master key was leaked online. Thanks to segher and Wanda for finally giving me closure on how the whole thing was computed : https://media.ccc.de/v/38c3-the-master-key

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. 🤦

#HDCP is such a frustrating fucking standard — punishes legitimate consumers and does nothing to stop piracy. Everyone who worked on it, and especially the executives who pushed for and continue to mandate it, should feel bad.

Fucking #HDCP …again! The mandatory technology that causes endless frustration but has never ever prevented even a single case of piracy.

Lástima que los promotores de este tipo de almacenamiento sean unos careros. Ellos mismos jodieron el #BD (#UHD también) con el #AACS (1 y el 2 con requisitos adicionales para lectores y grabadores), el requisito de instrucciones #SGX para reproducir UHD en ordenadores con procesador Intel, el #HDCP del #HDMI, códecs patentados y todas esas mongadas.
Es un estándar que ha buscado controlar toda la cadena desde el disco hasta el sistema operativo pasando por el computador que forma parte de la unidad lectora/grabadora de discos así como el procesador y chip gráfico del computador anfitrión.
En su día se utilizaron cintas de cassette para almacenar software porque era lo que se usaba para grabar sonido. Luego se utilizaron discos ópticos porque también se guardaba sonido en ellos. Más tarde vídeo. Y se aprovechó para aumentar las prestaciones. Pero no aprendieron de los #CD de música con #rootkit (por gentileza de #Sony) y decidieron meterle mierda extra.

Kennt jemand ein Device, was ein #HDMI Signal ohne #HDCP Verschlüsselung in eins mit HDCP wandeln kann? Ich habe hier eine #SDI basierte Produktionskette und muss auf einen #Projektor, der zwingend HDCP verschlüsselte Signale gefüttert bekommen will. #eventtech #videotech

Etwas Recherche ergibt: Womöglich besitze ich bereits einen #HDMI #Splitter, der #HDCP umgehen kann.
Damit könnte ich möglicherweise eine Präsentation auf #OSX über #HDMI an einen #Videoswitcher ausgeben an einen Beamer.
Ich frage mich, warum das nicht in der Produktbeschreibung steht und finde eine mögliche Antwort bei Heise:
Das Umgehen das #Kopierschutz des #MacBook Outputs ist – auch wenn ich ausschließlich von mir selbst erstellte Präsentationen oder Videos darüber abspiele – in Deutschland illegal.
https://www.heise.de/meinung/Kopierschutz-Kopf-Tisch-5021833.html
Ich stelle mir das Gesicht meines #Apple nutzenden Kunden vor, wenn ich ihm sage: Sorry, dein MacBook geht mit meinem Beamer nur mit diesem illegalen Gerät, kann ich nicht machen. Ich glaube, der wird mich schlicht für inkompetent halten und nicht zahlen wollen.
(Ich arbeite in der #Veranstaltungstechnik, da sind Dinge anders als in Eurem Wohnzimmer, u.A. sind die Beamer vieeel größer. Oder manchmal auch gleich open air LED-Leinwände auf eigenem Schwerlast-Trailer…)
