Can I run two 4k (3840x2160) displays at 60hz on a Macbook Pro 13" 2015 [duplicate]

I think the title says it all. Can I run two 4k (3840x2160) displays, both at 60hz on a Macbook Pro 13' 2015? I understand they might need to be SST and each connected to a Thunderbolt 2 port. But I cannot get a confirmation whether that setup would work.

Simultaneously supports full native resolution on the built-in display and up to 3840 by 2160 pixels on up to two external displays, both at millions of colors. … Support for up to 5120-by-2880 resolution at 60Hz on a single external display (model with AMD Radeon R9 M370X only)

Unfortunately, it does not state at what frequency the two displays can be run.

With OS X Yosemite v10.10.3 and later, most single-stream 4K (3840x2160) > displays are supported at 60Hz operation on the following Mac computers: … MacBook Pro (Retina, 13-inch, Early 2015) and later. MacBook Pro (Retina, 15-inch, Mid 2014) and later

Unfortunately it does not state whether two displays can be run at 3840 by 2160 at 60hz

Solution 1:

Assuming that you are using an Early 2015 MacBook Pro 13", it uses the Intel Iris 6100 chip.

From the review of the Intel Iris 6100 by NotebookCheck:

All Broadwell GPUs support OpenCL 2.0 and DirectX 12 (FL 11_1). The video engine can now decode H.265 using both fixed function hardware as well as available GPU shaders. Up to three displays can be connected via DP 1.2/eDP 1.3 (max. 3840 x 2160 @ 60 Hz) or HDMI 1.4a (max. 3840 x 2160 @ 24 Hz). HDMI 2.0, however, is not supported.

The capability is there to support up to 3 displays with a max resolution of 3840x2160 @ 60Hz.

You connect it via mDP (mini Display Port) through the Thunderbolt 2 port.

Solution 2:

You certainly can:

It's even at 60Hz, and supports HiDPI scaling:
