I'm currently running a Dell U2715H at its native resolution (2560 x 1440) via DisplayPort as an external display, and I'd like to add another at that same resolution. The Apple specs on this model don't say anything about two external displays.

Is it possible to run two external displays with this model?

Not according to EveryMac who are usually spot on with their info, including unsupported 'hacks', none of which are mentioned for this model.

This model can simultaneously support the internal display at full native resolution and up to 4096x2304 on an external display in both extended desktop (second workspace) and video mirroring (internal display duplicated on the external display) modes.

  • I saw the EveryMac page, but it essentially said the same as the Apple specs page. I find it curious that a 13" Macbook Pro has the power to run two displays (albeit maybe not at 2560 x 1440), but the iMac can't. Additionally, most of the Apple specs list a total supported resolution across all external displays, which in this case could mean two 1080p displays. – Andy Rice May 6 '16 at 16:09
  • Then empiricism is your next move. First, see how many ports it has... – Tetsujin May 6 '16 at 16:14
  • The iMac has two Thunderbolt ports, and the support page lists a total supported resolution of 4096 by 2304, so in theory it should support at least two 1080p monitors. But I haven't been able to find anything definitively confirming or denying that this is the case, hence my hesitation at pulling the trigger on a 2nd monitor. :) – Andy Rice May 6 '16 at 16:34
  • Then borrow one ;-) – Tetsujin May 6 '16 at 18:40

I bit the bullet and bought another DisplayPort monitor (Dell U2414H), and sure enough, it works out of the box! I'm currently running a total of three displays - the iMac built in at 1920x1200, the 24" Dell at 1920x1200, and the 27" Dell at 2560x1440.

Yes you can run 2 displays

Then a free download from duetdisplay.com to install the app on this model of iMac

Turn off iTunes backup to save space
