Prime Video not streaming in HD because of HDCP?

Hello,

So I was trying to watch the Ministry of Ungentlemanly Warfare on my PC today and everything was super pixelated. When I clicked on the gear settings it was set to 'Best', but there was a message (screenshot attached). This has never happened before and I am not sure why it's happening now. I updated drivers and Firefox and it still showed this error. There is no such error on Netflix or Hotstar so I'm totally perplexed.

Anyone else getting this? Anyone know the fix?

If it helps, I have a 3080Ti which is connected to my LG 27UK650-W via the included DisplayPort cable, which I'm not sure which version it supports, or if that even is a thing.

Anyway, looking for some help, please. Thanks for reading!

Have you tried using the Prime web app from the Microsoft Store? I use that and the HD works fine. Firefox had this issue a while ago but afaik it got resolved.
 
Do you have DRM disabled on firefox? Maybe Prme is preventing HD playback due to disabling DRM. I know both Netflix and Prime do this, but I don't know why only Prime is affected in your case.

Maybe try with the webapp as described above or a chromium based browser and check if you get the same results?

Finally, certified DP cables (which is what LG is bound to include in it's packaging), even the bare minimum DP 1.0 or 1.1 supports atleast FHD. DP1.2 supports 4K.

Also what OS are you running this on?

If Windows, any recent updates that may have broken something?
