MacBook Pro (Retina, Late 2013) and Mac Pro (Late 2013) computers can use 4K Ultra HD TVs with OS X or Windows (using Boot Camp). 4K Ultra HD TVs using these specifications are supported via the HDMI port:

• 3840-by-2160 resolution at 30Hz
• 4096-by-2160 resolution at 24Hz (mirroring is not supported at this resolution)

Ports and configurations for 4K Ultra HD TVs

With the MacBook Pro (Retina, Late 2013), you can connect:

• One 4K Ultra HD TV to the HDMI port and one Thunderbolt or third-party (non-4K) display via Thunderbolt.

With the Mac Pro (Late 2013), you can connect:

• Two 4K Ultra HD TVs¹ and up to two 4K displays via Thunderbolt.


¹You can use the HDMI port for one of these and a Mini DisplayPort to high-speed HDMI adapter for the other. If you do, don't plug the second Ultra HD TV into the bottom two Thunderbolt ports on the Mac Pro since they are on the same bus as the HDMI port. Mac Pro (Late 2013): Using multiple displays explains in more detail how to use the different Thunderbolt configurations on the Mac Pro (Late 2013).
