Did you get streaming services to stream 4k? That was some bullshit I discovered when I bought my first 4k TV, that streaming services artificially limit quality for browser and Linux streaming.

What is you solution for remote controlling? I used one of this mini keyboard+mouse combo in a shape of controller, but mine was really trash. Most of the time I used a good mouse that worked ok on the couch surface and some mouse binds to pop up a virtual keyboard. But I was never completely happy with the solution.
