Can't get 1080p playback and screenshots are black on Prime Video

Hi vista_fan89! Its been quite a while since this issue was raised and I do not know if you have solved the problem.

I had downloaded the Chromium Edge and was looking for a solution to this problem myself as well. Reading a lot of answers and the idea of toggling the DRM settings here, led me to reading about Multi-DRM technology and I myself have tried to toggle a few settings here and there.

Upon 2 hours of analysis, I have come to conclude, atleast for my PC, that enabling both Widevine and PlayReady DRM seemed to do the trick.

I know your issue was only for Prime Video and I tried disabling PlayReady DRM which worked fine with Prime Video, however Netflix did not seem to go along so well.

Apparently Netflix prefers PlayReady DRM while Prime Video seems to be more biased towards Widevine.

I tried taking a screenshot as you suggested but ended up at a very bad scenario. The screenshot was of course black to prevent piracy, however Prime Video degraded my resolution at the very moment I took a screenshot.

Now I have both PlayReady and Widevine DRM enabled and both Prime Video and Netlfix seem to play 1080p resolutions on my screen.

However, one thing which still puzzles me is that earlier Prime Video used to show HD1080p but now its showing HD. The quality seems the same to me.

I hope this helps you out if your issue is still not resolved.

PS: Does anyone know how to check the streaming quality on Netflix(Chromium Edge)?

Cheers!
