Asus has kindly decided to equip the Prime with a better 600-nit SuperIPS+ panel, which has been optimized for outdoor viewing. The 1280 x 800 Gorilla Glass screen is beyond bright and has very, very wide viewing angles; there’s no color distortion at any angle. You can toggle the SuperIPS+ mode on and off in the status control panel, though the plussed SuperIPS setting is really just designated for "outdoor use." The difference isn’t all that noticeable indoors — it’s a tad brighter when SuperIPS is switched on — however, when I took the tablet outside the difference was more drastic.
