This 32 inch IGZO Sharp 4K Ultra HD monitor has a resolution of 3840 x 2160 and offers 1.07 billion color palette with and 800:1 contrast ratio.
This comes after Apple's recent announcement of Mac Pro launch; the upcoming Mac Pro will support up to three 4K displays. As reported earlier, Mac Pro might be available from December 16 (according to a German authorized reseller).
There has also been a rumor of Apple preparing its own 4K displays. This speculation came up when a new lot of display panels appeared on AUO signalling a possible launch of Apple's Thunderbolt displays.
