Apple Is Going To Launch MacBook Pro With 2880x1800 Displays In Q2 2012
According to a
The MacBook Pro with high resolution display would presumably be a 15 inch model which currently carries 1440x900 resolution. By doubling the display resolution, Apple would increase the number of pixels fourfold and allow developers to easily scale existing programs.
It is known that Intel’s expected Ivy Bridges can support resolutions up to 4096x4096 pixels. However, Apple has already included "HiDPI" modes in Lion to provide support for double resolution. Moreover, Apple has included high- res artwork in Lion with icons at 1024x1024 and images for desktop at 3200x2000 pixels.
Apple is not the only company wanting to add this possibility. Microsoft is also working on adding support for high resolution displays in Windows 8.
