A tad surprised that curvature isn't discussed? With such a massive screen, the distance from your eye to the middle of the screen, and eye to the corners, are very different - unless you sit far away. Your eyes thus need to change focus all the time. That's AFAIK why those ultra wide screens are curved - and I find that the more curve they have (smaller radius), the better it is. With such a massive screen, I guess it would be best if it was part of a sphere! (Curved both ways)
