Can I connect two 34" LG 34UM95-P to a Retina Macbook Pro 13? I have a Macbook Pro Retina, 13-inch, Late 2013 with Intel Iris Graphics. I'd like to get two LG 34UM95-P 34" 3440x1440 screens for it. 

Unfortunately, LG writes that it the only compatible Mac is the 2014 new Mac Pro.

Currently I have two 27" displays with 2560x1440 resolution connected, and occasionally open the lid for a total of 9.13M pixels (at the highest interpolated resolution). But two of the LG screens would be 9.9M pixels, and over external connections as well.

I've found reports that the screen works with recent Macbook Pros, but…


I only found ones that cover the Macbook Pro 15" with discrete graphics (and sometimes emphasize that fact)
I want to connect two of the screens, not just one


Apple's tech specs mention:


  Dual display and video mirroring: Simultaneously supports full native resolution on the built-in display and up to 2560 by 1600 pixels on up to two external displays, both at millions of colors


Unfortunately, the 34" screens have ~20% more pixels than that.



Will I be able to use two of these screens with the computer I have?
You ABSOLUTELY can do this.  

The statement on the box is wrong. You can use either two mini-display port to displayport cables, or two Thunderbolt cables.

My statement was based on the fact that you can (according to Apple's documentation) run two Thunderbolt monitors on that laptop, and the available resolution on the Thunderbolt cable is clearly capable of 3440x1440.
