This question is NOT about how to connect two Thunderbolt displays — there are plenty of questions asked here about that, but whether or not the graphics chip in the Early 2016 MacBook 1.3 GHz Core m7 (M7-6Y75) has the power to drive two external displays (Apple Thunderbolt Display) at 2560 x 1440 resolution?

Here's the backstory. I have a MacBook Pro connected to two Thunderbolt displays. I am considering replacing it, but I love my dual Thunderbolt displays. I would like to replace it with the newest 2016 MacBook, but concerned it won't have enough power to drive the two displays.

What those specs are saying is that this model can simultaneously support the internal display as well as up to 3840x2160 at 30 Hz on an external display, both at "millions of colours."

In other words, connecting two external Thunderbolt Displays is not officially supported by Apple. The two displays are the internal display and an external display.


I should have looked closer to the tech specs on the Apple website:

Dual display and video mirroring: simultaneously supports full native resolution on the built-in display and up to 3840 by 2160 pixels at 30Hz on an external display, both at millions of colors.

Based on this I can only run my built-in display and one external display, and only at 30Hz.

  • There is a hack to run it at 60Hz. Check out 9to5Mac - How-To: Drive a 4K display at 60 Hz with the 2016 MacBook: 9to5mac.com/2016/06/04/…
