It looks like Sharp is planning full support for OS X in its upcoming 32-inch 4K IGZO touchscreen LCD LED monitor (PN-K322B) expected to launch in the US this fall. Sharp previously announced the 36 mm thin 4K panel with pen support in July, but Macotakara.jp snapped the photo above of Sharp demoing the display running OS X from a connected MacBook at the Ceatec Japan 2013 show over the weekend.
From the translated report, it sounds like Sharp plans compatible OS X drivers as a download in 1-2 months.
Apart from touch support, the monitor is much the same as the 32-inch 4K IGZO display that we were quite impressed with when Sharp first showed them off at CES in January.
