I have a 4K 120Hz TV that I have blocked from internet access on my router (because it is spyware with no way to turn off the built in microphone) and I have a desktop that supports 4K but I don’t want to run my desktop into the ground streaming on it all the time.
I’d like one that isn’t American I guess if that really matters (seems like it kind of does) but I noticed options are limited unless you want to spend $600 on a mini PC which I don’t.
I’d like to spend like $200 max if possible for this if possible.


Not directly. There are some hacky work-arounds that may or may not work:
