I wonder if the work on waydroid for the steam frame will translate into being able to easily run Android apps like SmartTube from big picture mode.

Edit: Apparently there is an unofficial waydroid installer, and it adds all Android apps to the big picture mode UI. So I would just install that and use the Android TV Jellyfin app and SmartTube.

Abandon “legal” streaming, it doesn’t work because of DRM.

Cable Matters sells plenty of different DP->HDMI 2.1 adapters that work with VRR. The main issue here is that you won’t get CEC if you use those.

Fun fact, all of the audio codes are proprietary too. You won’t find a HDMI surround sound splitter on Aliexpress. Say no to HDMI, say no to E-ARC.
