I am about to buy one. What do you recommend for a jellyfin setup with it?

So far I got:

• Projectivity Launcher
• set speed to 0.5 for snappier experience
• debloat via adb https://florisse.nl/shield-debloat/

Additional Q: if it can upscale 1080 to 4k, does that mean I don’t need my 4k collection anymore? It sounds too good to be true.
