Apple’s OS X 10.9.3 Update Will Support Retina Resolution for 4K Displays
An upcoming OS X Mavericks 10.9.3 update will soon allow Apple’s (NASDAQ:AAPL) Mac users to run 4K displays at full Retina resolution, Apple Insider reports. The enhanced display option will be available over HDMI and possibly Thunderbolt display output ports. The “pixel-doubled” display resolution will allow content that is displayed on 4K monitors to appear as sharp as it looks on the late-2013 MacBook Pro’s native Retina display screen. As noted by 9to5Mac, users that attached an external 4K monitor to their Mac’s running OS X 10.9.2 would only see content displayed on a larger scale with display elements spread out.
The scaling display enhancement was spotted in Apple’s beta version of the upcoming OS X 10.9.3 update by developers. Besides the “pixel-doubled” display resolution for Macs, the latest OS X update will also boost the Retina MacBook Pro’s connected 4K display refresh rate to 60Hz.
According to Apple insider, OS X 10.9.2 only outputs to a 4K display at 24Hz or 30Hz. The current refresh rate limit of 30Hz makes some animations appear “choppy.” Per Apple’s 4K display support page, the highest output resolution previously available for the late-2013 MacBook Pro and late-2013 Mac Pro was a 4096 x 2160 pixel display output at a 24Hz refresh rate. However, this display setting would spread out display elements. Mac users also had the option to output to an external monitor at 3840 x 2160 pixels with a 30 Hz refresh rate. Neither setting was close to the native display resolution.
