    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.

    Sorry to dig up an old post but I wanted to throw this out there. These are only 1080P monitors but I'm using 3 of them plus my onboard monitor at work without issue on my 13 inch MacBook Pro w Touch Bar. I'm using a Dell "triple display" USB 3.0 dock. It works fine in MacOS and Windows 10 (boot camp).

    Ok considering the host and you are generically stating 13” MBP TB I think we should all be more specific - especially the OP cause the thread started in 2016 but was updated when he had his MBP in 2017.

    2016 MBP and 2017 models differs in chipsets and what they can support in terms of total external resolution. So guys update which models you have first. Next outline which ports specifically on your respective models is connected. If I recall the 2016 MBP TB only supported 2 USB-C Ports at full TB3 speeds. The 2017 model supports 3 USB-C ports at full TB3 speeds. Knowing which port can do what will affect resolution and monitor connected.

    I think that maybe part of the confusion. Once that’s cleared up then maybe in Preferences - Displays will resolve a bit better; hopefully.

    Can you please share your MBP specs and update us as to how your setup is working? Any issues?

    The Dell Triple Display USB 3.0 dock does not use the display output of the MacBook Pro's graphics chip. It uses DisplayLink which uses USB to transmit graphics information bypassing the limitations of the graphics chip. DisplayLink has it's own limitations though (not good for video or games because of USB bandwidth).

    I have a mid 2017 13inch MBP with touchar and cannot get 3x 1440p monitors to display video. I'm only able to get 2. I think I read somewhere that it can support 3x 1080p, but not 2k+.

    Anyone have any other insight, or suggestions?
    Is getting an eGPU the only solution to getting 2+ monitors?

    It's when I'm in Closed Clamshell mode.

    With the Dell "triple display" dock, none of the 3 displays are connected to the graphics chip of the MacBook Pro, so they won't be good for video or games. The Dell dock uses DisplayLink to transmit video data over USB (5 Gbps) using compression. A normal 4K 60Hz signal from the graphics chip is over 11 Gbps (3840x2160 60Hz, 24 bit color).

    If you really need 3 displays, you can connect two of them directly to the graphics chip (via one or two of the Thunderbolt 3 ports). You can use two of the Thunderbolt 3 ports, or use just one Thunderbolt 3 port with a Thunderbolt 3 device that has two Thunderbolt 3 ports and a DisplayPort output (such as a Thunderbolt 3 dock like the CalDigit TS3 Plus) or you can use a Thunderbolt 3 to Dual DisplayPort adapter.

    Then for the third display, you can use a DisplayLink adapter with any USB port (any of the remaining Thunderbolt 3 ports or a USB port on a Thunderbolt 3 dock). With a triple display dock, you could have five displays (two native displays, three DisplayLink displays). A list of devices that use DisplayLink are at http://www.displaylink.com/products
    They have devices that support one, two, or three displays.

    The driver page at http://www.displaylink.com/downloads/macos mentions incompatibility with the latest macOS 10.13.4, but that's not a problem with BootCamp.

    To convert USB-C (or Thunderbolt 3) to USB-A, just use any USB-C (male) to USB-A (female) adapter like the one Apple sells.
