I bought a monitor since the smarts in my smart-tv died, making the entire display unusable. Now I wanted to use a separate SBC for smarts in the “dumb” monitor. I would have gone for a modded fire-stick, but Amazon in their infinite wisdom, sunset all versions except the 720p potato and the smart-speaker-cube. I’m currently using a RaspberryPi 4 and looking at argon one for a remote control case. Googles widevine does limit the DRM on some content I “own” though. With Amazon on course to EOL the more sane sticks, are there any well-moddable streaming-sticks/boxes, that bring the relevant codecs and DRMs?
It sounds like my case recomendation doesn’t fit your needs. However, the rest of what I said still stands
