I mean.. does it really need to get clearer than 1080P? i'm assuming the jump to 4k is a tiny difference compared to the jump from standard definition to 720P
if you've seen true 4k you wouldn't say this. go to ur local best buy and see if they have the new sony 4k tv's there which usually have some clips from new movies in 4k. shyt will blow you away.
I literally went back and looked at my TV in disgust after seeing true 4k in action. Its a huge leap forward. IMO its like going from 480p to 1080p. You won't ever wanna watch anything else blow 4k after seeing it in action.
