    Hey, guys!
    Wondering if anyone knows whether or not it is possible to run three monitors (in addition to the MacBook screen) with the 13" Touch Bar MBP. I know apple says you can run 2x4k, but what about 1x4k + 2x1440? Perhaps with some daisy-chaining?
    Thanks in advance!

    It should work, but OS X doesn't support displayport daisychaining.

    Hmmm... I may be confused, but doesn't this suggest that it can daisy-chain?
    MacBook Pro (13-inch, Late 2016, Four Thunderbolt 3 Ports) and MacBook Pro (13-inch, Late 2016, Two Thunderbolt 3 Ports) support up to two Thunderbolt displays using Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapters and daisy-chaining.

    Like I said, I fully expect that I'm just missing something...

    You can daisychain with Thunderbolt displays, not displayport ones.

    You can put Displayport monitors at the end of the chain. So you could have: Mac-->TB Monitor-->Displayport Monitor.

    Gotcha! So maybe I could go with a 4k display through one port and then run a couple of 1440's off a hub connected to another one (using two totals ports on the computer)?

    Sure. Just make sure the USB C dock you get can handle both monitors at 60hz.

    Sorry to resurrect an old thread, but now that I've got my 13" MBP and 3 monitors, I'm not having any luck.
    Right now I've got 2 4k's running through 2 display port dongles on my left hand USB ports. If I try to hook up a third monitor either via dongle or a hub, I get a black screen. For what its worth, I can run an iPad as a third external monitor via the Duet app just fine.
    Any advice?
    Thank in advance!

    I haven't, but I don't have an external keyboard and mouse :/
    I assume that it's handling the processing for the iPad screen though, and it runs great even with the internal display and the other two monitors.

    The 2015 13" Can run three displays simultaneously, so you can either have 2 external + internal or 3 external, with discrete graphics card you can have 4 simultaneous displays, I suppose it should be the same.

    Not when any of the displays are 4K it can't.

    Of course it can, I run two 4k screens @60Hz easy on 2015 13" with the actual laptop screen running 2560x1600@60Hz, 2015 15" with discreet card can run one more monitor.

    On a "MacBook Pro (13-inch, 2016, Four Thunderbolt 3 Ports)" I can't get 3 external displays to work.
    They are 3 DELL U2415 display (1920x1200).

    I connect 2 of them using usb-c to Displayport cables and the third one using Apple USB-C Digital AV Multiport Adapter (with an HDMI cable).

    In the 'System Information' app under 'USB' I can see all 3 cables connected: one shows up as 'Apple USB-C Digital AV Multiport Adapter' and the other two show up as 'Billboard Device'.

    Nevertheless, regardless of the combination, only the first 2 out of the 3 connected screens will show a picture. Closing the laptop lid with magic keyboard and magic mouse connected won't change a thing: the built in display will shutdown but the third external display won't lit up.
