I just hook up a (linux) laptop to my TV, personally. I have a mouse (and a bluetooth keyboard which I rarely use) to interface.

I have no idea if that would in some way impact something like streaming quality because I don't have any streaming services; I live in australia where the streaming companies simply don't bother organising streaming rights for worthwhile media. I also like to own things I want to rewatch.

If I wanted to get fancy (and if I had a TV capable of connecting to the internet, which I don't) I might consider setting it up as a media server or look at NAS solutions, but my laptop is perfect for me as is.
