'Tis a bit of a silly article, I'd go insane trying to keep my application windows in the sweet spot for viewing them at a 22 degree rotation. One thing strikes me that I've wondered about when I would rotate some of my monitors: the color shift/viewing angle issue. I can understand in older monitors that have different viewing angles for horizontal and vertical, but some of my monitors over the years have been 176 degrees H + V or 178 degrees H + V, so why is there such a marked difference in what is being displayed when it is at 0 degrees rotation vs 90 degrees rotation?
