I use a beamer instead of a tv but it is not complicated to dedicate a small computer like a gigayte brix or an old laptop and use the tv/beamer as the screen. Be it with kodi or using regular apps doesn't make a huge difference these days. With the advent of hidpi monitors, all modern OSes support scaling the icons/text/widgets so it is perfectly viewable from a few meters of distance.

I use a wireless keyboard+trackpad combo as a remote which I leave out of the way inside my living room table when not in use.
