In the case of the 3200x1800 setting this means that the display is rendered offscreen at 6400x3600 which may cause performance issues when being driven with the Intel Iris graphics of a Macbook Pro with Retina Display or the entry level 21.5” iMac. All of these are handled the same way as on the Macbook Pro with Retina Display where the display is rendered offscreen at twice the selected vertical and horizontal resolution and then scaled down to the panel. Apple now gives the user options for display scaling which includes settings for a workspace that looks like 3200x1800, 2560x1440, 1920x1080, or 1280x720. In 10.9.3 Apple has greatly expanded the list of compatible 4K displays and has introduced scaling modes for those who prefer sharper UI elements over display real estate.Īnand took a look at the changes to 4K support in the first beta of 10.9.3. This made for poor usability on monitors like the Dell UP2414Q which is only 24” and has extremely small UI elements when running unscaled at its native resolution.
Only a small group of monitors from ASUS and Sharp were supported for running at 3840x2160 with a 60Hz refresh rate, and the scaled display options that Apple introduced with the original Macbook Pro with Retina Display were unavailable. Prior to 10.9.3 the support for 4K displays on OS X was lacking.
2560X1440 ON 4K MONITOR MAC OS UPDATE
The most major improvement of the update is the improved 4K (3840x2160) display support on OS X. One of the most interesting things about the update is not in its content but in how Apple opened up their beta seed program to all users when it was traditionally reserved for those who are part of Apple’s developer program. The update comes after nine weeks of beta testing, each week with a new release.
Today Apple released the long awaited OS X 10.9.3 update.
