This was one of my fears of 4k passive that I have brought up before... the idea of more lines of resolution is great, but the FPR becomes much smaller and thus easier for light to blead around.
Think about having a flourescnet tube light and putting a thick dowel or broom handle in front of it. If you line it up just right, it will block out almost all the light, move a bit and a little of hte light pops out from behind it but it's still mostly blocked.
Now imaginge a really thin light source and block it with a thick piece of string or something. If you move much at all the ENTIRE light source will no longer be blocked.
Because the light source of an LCD is behind the panel and the crystal must be stacked 3 deep in front of it, the FPR will always have some margin of error and as the FPR eliments get smaller and smaller the tighter that sweet spot is going to be...
Basically I figure it will have to opposite effect of higher resoultion in that the higher th res the closer you have to be to appreciate it, as the FPR gets smaller, the further you will have to be back to get the same sized sweet spot.
