What Steamymoomilk had stated previously is that Linux on Apple Silicon is better than macOS for gaming. But Proton support is not only a very new feature to Asahi Linux but also still has issues.
x86 Linux > macOS (with or without Crossover) > Asahi Linux on Apple Silicon macs (what the previous commenter said was better than macOS).
For a TV that can be set up as a 'dumb tv' and you can even reject the terms and conditions: Hisense surprisingly.
My partner got one a month ago and it was stupid simple to set up and asks you if you want to set up as a Smart TV or as a Basic TV.
Also ditch the Roku, that's absolutely just as bad as using the onboard smart tv functions. Theres NVidia Shield, Apple TV, or with a little setup a Raspberry Pi running Kodi.
