With new claims that Apple is set to release a new 15" MacBook Pro offering a resolution of 2880x1800 early next year, Apple's work on its HiDPI software support has also been gaining renewed attention. By doubling the resolution in each dimension over the existing 1440x900 MacBook Pro, Apple would achieve four times the number of pixels and provide developers with an easy way to scale existing artwork.
Evidence of Apple's continued work on HiDPI has shown up in developer builds of OS X 10.7.3, with the "Get Info" window for applications seeing the addition of an "Open in HIDPI mode" checkbox. But while that checkbox would presumably automatically use higher-resolution fonts and graphics that would display at the same absolute size as existing elements, it has not been functional in developer builds where it is present.
Oh, please. I'd love to have an 21.5 inch iMac with a 3840x2160 resolution, that would be AWESOME
AMD's 7000 series supports 4kx4k which is about 16 million pixels. Does that mean 5120x2880 is possible since it's only 14.7 million pixels?
