OS X 10.9.3 beta contains special pixel-doubling mode

updated 09:57 am EST, Fri March 7, 2014

Appears intended to support 4K displays

The OS X 10.9.3 beta supports new graphics scaling options which appear aimed at supporting 4K displays, users say. While a Mac Pro or Retina MacBook Pro can connect to a 4K monitor, they normally do so at resolutions up to 4096x2160 at 24Hz, which results in OS X's interface being spread out and shrunk, and choppiness in the case of things like the mouse cursor. The MacBook Pro can alternately use 3840x2160 at 30Hz, but this isn't an improvement.

10.9.3 gets around this by allowing pixel-doubling, which scales up OS X's interface such that it should have its normal appearance. The MacBook Pro can also output at 60Hz; the Mac Pro is capable of 60Hz 4K using MST (multi-stream transport) over Thunderbolt.

Apple is unlikely to build 4K support into any of its own computers or monitors for the foreseeable future. Native 4K is still expensive, although costs should come down by the end of 2014 as more manufacturers begin to ship products.

    60 Hz hurts my eyes...

    Need closer to 100 Hz.

    Huh... 4K expensive? Now come Dell can afford it and Apple cannot?

    Dell can afford it because they're nowhere in the same league as Sharp in terms of quality, reliability, or customer service.
