based on my opinion, it is stupid to actually buy 4k tv, why? you imagine that we have dvd resolution 480p and you are trying to display it at 4k? versus 480p displaying at 1080p, try youtube 480p resolution with your pc connected to the 4k vs 1080p, next you try 1080p on 1080p and 1080p on 4k, the line is there, it is no illusion, even for 480p you almost want to throw your tv, 4k?
