SOFTWARE DEVELOPER Apple has started seeding its Mac OS X Mavericks 10.9.3 beta to developers, which reportedly will be an interesting release for those who own a 4K display.
Although not disclosed in Apple's release notes, 9to5Mac has discovered that Mac OS X 10.9.3 delivers support for those who have their Macbook hooked up to a 4K display.
Macbook owners running Mac OS X 10.9.3 will be able to set their 4K displays to run the operating system at a pixel-doubled 'Retina' resolution, resulting in much sharper content on the bigger screen. Before this update, content from the Macbook will have showed up only at a larger scale with window elements spread out.
What's more, the software update - which likely won't be released for a few weeks yet - allows the Retina display Macbook Pro to support 4K displays with a refresh rate of 60Hz, which likely will make the display look much smoother compared to output at refresh rates of 24Hz or 30Hz.
9to5Mac gave the new feauture a spin, concluding, "Our tests connected a late-2013 MacBook Pro with Retina display to a 4K Seiki monitor over HDMI. Running OS X pixel-doubled on a 4K display means content is much sharper than before. It is the same as running a Retina MacBook Pro at standard Retina resolution or as using a Retina iPhone or iPad."
This news also seems to suggest that Apple will release a 4K resolution display at some point this year, although the company has yet to announce that it will. According to rumours, however, the firm is developing "high resolution standalone displays".
Apple has yet to comment on the reportµ
