Let's get straight to it: The new Zenbook Prime Ultrabooks have the best displays of any Ultrabooks introduced so far. The Zenbook Prime 11-inch UX21A and 13-inch UX31A and UX32VD all offer optional full HD 1080p (1920 x 1080 pixel) displays. This is a big update from the last year's screen resolutions -- 1366 by 768 pixels on the 11-inch UX21, and 1600 by 900 pixels on the 13-inch UX31. More pixels means you'll see sharper text and images, and you won't have to scroll as often.

Most Ultrabooks today only offer 1366 by 768 pixel resolution displays. Resolution-wise, the Zenbook Prime's closest Ultrabook competitors are the , and , all of which have 1600 by 900 pixel resolution on their 13.3- to 15.6-inch screens.

None of the other Ultrabooks use the offered on the Zenbook Prime full HD displays. Screens with IPS have brilliant color and better viewing angles.
