“As part of Thursday’s OS X 10.9.3 update, Apple finally added improved support for high resolution 4K displays,” Jim Tanous reports for TekRevue. “Thus far officially available for only the 2013 Mac Pro and MacBook Pro with Retina Display, the 10.9.3 update gives users the option to configure their 4K displays at “’Retina’ resolutions using System Preferences. Users could previously attain Retina-like resolutions for 4K displays by manually enabling OS X’s HiDPI mode, but the update makes the process as easy as configuring the built-in display of a Retina MacBook.”
“In OS X 10.9.2 and below, users with 4K displays connected to their Macs would see a list of compatible resolutions by default,” Tanous reports. “Native 4K resolution was available, but most users would find it too small for standard productivity work. The only other option, aside from the aforementioned HiDPI tweaks, was to use an upscaled lower resolution, such as 2560×1440.”
“Despite the improvements in Thursday’s update, support for third party 4K displays in OS X still has a long way to go,” Tanous reports. “Apple released Knowledge Base Article HT6008, explaining that only a select few displays are officially supported, especially at the important 60Hz refresh rate threshold, and that users may have to update their displays to ensure compatibility. Apple currently cites official compatibility with only the Sharp PN-K321 and Asus PQ321Q, and they’re not kidding.”
