OS X Yosemite 10.10.3 extends support for 4K monitors

In addition to the news widely disseminated by us, the OS X Yosemite 10.10.3 some interesting ones under the cap.

As the 9to5Mac previously reported, Ma s supported some 4K MST displays (multi-stream transport, a feature that allows the connection of monitors in a chain) at a frequency of 60Hz; most monitors now single-stream transport (38402160 pixel resolution) officially supported on the 60Hz frequency, as we can see in this Apple support article.

Dell Monitor (UP2414Q)Dell UP2414Q Monitor. One that now works with newer Macs.

What does this mean in practice? That the latest Macs are compatible with cheaper 4K monitors, which do not have the feature multi-stream transport, present in DisplayPort 1.2.

Here are the Macs that now support 4K displays single-stream (3840 × 2160 pixel resolution) at 60Hz:

  • MacBook Pro (Retina, 13 inch, early 2015)
  • MacBook Pro (Retina, 15 inch, mid 2014)
  • Mac Pro (Late 2013)
  • iMac (27-inch, late 2013 or newer)
  • Mac mini (Late 2014)
  • MacBook Air (early 2015)
  • MacBook (Retina, 12 inch, early 2015)

And those that support 5K displays single-stream (4096 × 2160 pixel resolution) at 60Hz:

  • Mac Pro (Late 2013)
  • iMac (Retina 5K, 27 inch, Late 2014)

In the specific case of the new MacBook, it can support the resolution of 38402160 pixels at 30Hz or 40962160 pixels at 24Hz via HDMI cable. For 60Hz support, if you need such a monitor single-stream (DisplayPort) in all cases, of course, you will need to use adapters since the machine only has a USB-C port.
