this has little to do with the resolution, though. maybe 4k just gets the benefit of being compressed with better codecs.

for me at least, watching shows/movies at typical viewing distance, a well-encoded 4k->1080p mkv is only very slightly less sharp and is vastly smaller to store on the media server.
