Dabar nerandu gero saito, kur buvo viskas su geometriškai su schemomis 
išaiškinta, kodėl reikia teliko virš 130" dydžio, bet kažkiek sueis ir

Size matters

Curved screens work in commercial theater environments, where the screen 
can run wall-to-wall and floor-to-ceiling, because the entire audience 
sits within the curve. Everyone is “immersed.”

In a typical living room environment, with a smaller-but-more-affordable 
55- or 65-inch curved TV, the immersive area is effectively reduced to a 
sweet spot directly opposite the center of the screen and at a slightly 
shorter viewing distance than for a comparable flat screen. In the 
typical home, that spot can only accommodate just one or two viewers.

Anyone unlucky enough to be seated outside that area will have a more, 
well, bittersweet viewing experience. In fact, once you sit around 35 
degrees to either side of that sweet spot, the image closest to you 
appears foreshortened compared to the far side. Some viewers find this 
fatiguing as well as annoying because of the brain’s attempt to 
compensate for the distortion. Sit even farther to the side, and the 
screen's edge might completely block the near side of the image as it 
curls in front of it.

That sweet spot, however, grows in direct proportion to the size of the 
TV. That means you can remedy most of these problems by buying—you 
guessed it—a bigger screen. By most accounts, 70 inches is the minimum 
size needed to experience the immersive effects of a curved screen...


Bet realiai čia tas 70" minimumas yra pritrauktas už ausų. Faktinis 
minimumas yra gerokai virš 100", o default'inėmis sąlygomis, kai telikai 
dažniausiai žiūrimi gyvenamose patalpose iškart kelių šeimos narių, kaip 
jau minėjau, reikia 130" ir daugiau.
