10 09 03 osx update

In the recent 10.9.3 update to Mavericks, it was mentioned in the details about improved 4K display for certain Mac models. A Knowledge Base article reveals all.

First of all the recent 10.9.3 update to Mavericks was mainly a bug fix. Need we remind you not to update in the middle of a large or critical project?

  • Improves 4K display support on Mac Pro (Late 2013) and MacBook Pro with 15-inch Retina Display (Late 2013)
  • Adds the ability to sync contacts and calendars between a Mac and iOS device using a USB connection
  • Improves the reliability of VPN connections using IPsec
  • Resolves an issue that prevented Font Book from installing PostScript Type 1 fonts
  • Improves reliability of copying, editing and inspecting permissions of files on an SMB file server
  • Improves reliability of network home directories
  • Improves stability when installing configuration profiles
  • Improves login speed for users in Active Directory groups
  • Includes Safari 7.0.3

With a bit of digging, we found a Knowledge Base article that gave us more details:

 

Supported displays and configuration

You can use 4K displays and Ultra HD TVs with your MacBook Pro (Retina, Late 2013) or Mac Pro (Late 2013) computer. You can use these displays at the following resolutions and refresh rates with the built-in HDMI port.

3840 x 2160 at 30 Hz refresh rate
4096 x 2160 at 24 Hz refresh rate (mirroring is not supported at this resolution)
With OS X Mavericks v10.9.3 or later, the following DisplayPort displays are supported at their default 30 Hz using single-stream transport (SST).

Sharp PN-K321
ASUS PQ321Q
Dell UP2414Q
Dell UP3214Q
Panasonic TC-L65WT600

MacBook Pro (Retina, Late 2013) or Mac Pro (Late 2013) also support 60 Hz displays using multi-stream transport (MST). These displays need to be manually configured to use MST. Follow the steps below to use the display's built-in controls to enable this feature.

(Which we think when boiled down, it means that you have to have a Thunderbolt 2 equipped Mac!)

Sharp PN-K321: Choose Menu > Setup > DisplayPort STREAM > MST > SET
ASUS PQ321Q: Choose OSD menu > Setup > DisplayPort Stream
Dell UP2414Q and UP3214Q: Choose Menu > Display Setting > DisplayPort 1.2 > Enable
Panasonic TC-L65WT600: Choose Menu > Display Port Settings > Steam Setting > Auto

Your Mac will automatically detect an MST-enabled display. However, your display may require a firmware update to support 60Hz operation. Please contact your display vendor for details. If your specific DisplayPort display is not listed above, check with the display’s manufacturer for compatibility information.

 

There is also information for adjusting the 4K display.

Use System Preferences > Displays to adjust or scale the resolution on your display. This can make text and objects appear larger or give you more space on your screen. Hovering your mouse over one of the resolution options will show more detail on that option. To get a Detect Displays button to appear, press the Option key. To see all the available resolutions, hold down the Option key while clicking the Scaled button.
