OS X Mavericks 10.9.3 Beta Brings Support for Pixel-Doubled Retina Resolution on 4K Monitors

The newly seeded OS X Mavericks 10.9.3 beta has brought pixel-doubled 'Retina' resolution support for 4K monitors, reports 9to5Mac and Khaos Tian.

Before this update, users with Macs connected to a 4K display would simply experience their content on a larger scale with window elements spread out. Macs on 4K displays essentially were given ~4000 lines of room to accomplish their tasks. Prior to this 10.9.3 beta, users have solely been able to run their Macs at a Retina/pixel-doubled resolution using unofficial hacks.

Khaos Tian was also able to confirm OS X 10.9.3 brings support for 4K@60Hz on the new Mac Pro and the Retina Display MacBook Pro (late 2013).


Apple has yet to release a 4K monitor of its own. Hopefully these improvements bring us a little closer to that happening.
