Apple’s new OS X Mavericks 10.9.3 beta comes with a support feature that enables compatible 4K displays to be set at Retina resolution.
Before the update, Mac users who connected to a 4K display would just see their content appear at a larger scale.
But now words and images can appear at scale with Retina’s sharpness of detail.
According to MacRumors, Twitter user @KhaosT discovered the feature and tested it with both the late 2013 Retina MacBook Pro and redesigned Mac Pro in conjunction with Dell’s UltraSharp 24 Ultra HD Monitor.
The new settings in the beta mean Mac users can now set 4K monitors to run at double the amount of pixels as per Retina, with the inherent sharpness of graphics.
