4k no anti-aliasing &gt; 1080p maximum anti-aliasing.

I don't understand the comments about the distance. I sit at the computer at arm's length, maybe one and a half arms.

4k resolution without anti-aliasing looks significantly better than 2k with maximum anti-aliasing. I can't imagine how blurry the picture will be at 1080p.
I am sure that those who write about 1080p looks like 4k from a distance, either they are sitting on the couch at the other end of the room, or they have never used 4k monitors at the table.

I am pretty sure you need a better GPU to run 4k no AA than 1080p full AA, maybe thats why people prefer 1080p full AA.
