Up Close with the 13.3-inch 2560 x 1440 Panel on Next-Gen Ultrabooks
 

Although entry level PC notebooks will still ship with a 1366 x 768 panel, the high end of the market is quickly shifting to 1080p and higher resolution panels. Some of the most interesting notebooks at Computex launched with high DPI panels, such as the new Acer Aspire S7 and the ASUS Zenbook Infinity - both with 13.3" 2560 x 1440 displays. These displays offer comparable pixel density to Apple's MacBook Pro with Retina Display.
