he number of 4K displays slowly but steadily increases. With OS X 10.10.3 support the Mac operating system also “single stream” displays, among other things, also the new Retina MacBook spend a 4K image at 60 Hertz.
Apple has said in a new support document the extent to which support the own computer 4K displays at what resolution and what refresh rate. Is particularly interesting that the circle of supported displays has increased significantly by OS X 10.10.3.
In previous versions of the Mac operating system it was possible to drive multi-stream transport displays with 4K resolution at 60 Hz. Multi-Stream means that the computer image signals for different displays transmits over a single cable; as can be, for example, multiple displays “in a row”.
With OS X 10.10.3 it is just now also possible to drive through a DisplayPort connection 4K displays without multi-stream transport support with a resolution in the amount of 3840 x 2160 and 60 hertz refresh rate. This requires a 13-inch Retina MacBook Pro 2015 is a 15-inch Retina MacBook Pro 2014 is a current Mac Pro, 27-inch iMac from 2013, a Mac mini 2014 a MacBook Air 2015 or just the current Retina MacBook 2015th
Who in turn wants a 4096-by-2160 resolution with a single-stream display at 60 Hertz, must rely on a current Mac Pro or an iMac with Retina Display 5K. Even with these devices, it is possible only with OS X 10.10.3 approach to this display accordingly.
Who links the current Retina MacBook turn over an HDMI connection with a 4K display, must be content with a 3840-by-2160 resolution at 30 Hz or a 4096-by-2160 resolution at 24 Hz. As well as for the Mini DisplayPort connection adapter required for HDMI connection because the MacBook only has a USB Type-C port. However, a USB Type-C to DisplayPort Adapter, Apple has not yet available.
When 4K is not sufficient with OS X 10.10.3 also driving the Dell displays UP2715K at 5K resolution possible – a standard wall iMac or Mac Pro Retina 5K, the need to control the display with two DisplayPort cables. With such a configuration, according to Apple, other displays with a higher resolution than 4K compatible, the manufacturer does not mention explicitly the individual models.
Apple has incidentally corrected with the new support document, the previous statement to the effect that the current MacBook Air could maximum output a 2560-by-1600 image: Previously was testers noticed that the output of a 4K image is possible. However, the performance of the graphics chip meets at this resolution to the limit; the Retina MacBook that should be similar.
