49" is fairly small for a 4K TV; you have to sit quite close to be able to perceive the resolution difference and get the IMAX fill your peripheral vision effect.

[1] gives an ideal distance of 1 to 2 meters.

Gamers often do sit that close, so it would be interesting to see how well it does as a monitor replacement, like the 39" Seiki's that some are using. 49" UHD is the same as 4 24.5" 1920x1080 panels so would not need any sort of scaling in legacy operating systems.

Amusing experiment: have people hold their two index fingers in front of them aligned with the sides of their TV, with their elbows bent an 90 degrees. I find people tend to sit progressively further away from a screen the larger it is, so the screen size proportional to their field of vision remains the same.
