To have a massive wall of video, you need to have a home spacious enough for a whole spare wall first! I haven’t seen a <1m screen that would fit in the kitchen corner my TV occupies on an arm - I don’t even think a projector would work with a screen this relatively small. And where would the projector itself go if opposite of that corner is the couch/bed? Sit on my lap?
Or a Raspberry Pi. Is more expensive ($60 for my Pi 3), but I think it was worth it due to versatility and privacy. Stock Android TVs would be uncomfortable as they spy on you.
