Extended dual screen config for Macbook pro 2017 touchbar.

[fixitsvcs]

Hi All,

Currently i have a Macbook Pro 2017 Touchbar and need to connect to 2 external QHD screens.
By doing this i will need a dock. I have tried with a Dell WD-15 USB-C dock but the 3rd screen will only mirror the 2nd screen so it does not work even if the Macbook Lid is closed.

Anyone tried using with this Lenovo ThinkPad Thunderbolt 3 dock? Will this work for my intended setup?

The monitors i have are 2 x Dell UltraSharp 34 Curved Ultrawide Monitor - U3415W

Is the reason you want a dock to avoid the inconvenience of connecting two USB-C cables?

Otherwise just grab a couple of $15 USB-C to DP cables and off you go.

It's a matter of convenience. I do not wish to be unplugging all the cables daily when i bring out my Macbook.

I wish to have a setup like this but with the Lenovo Thinkpad Thunderbolt 3 dock. Will it be possible by using the Lenovo dock. Anyone tried this with Lenovo dock before i decide to purchase it?

Currently it is NOT possible to have multiple displays connected to a single TB3 port working in extended display mode.
No matter what hub / dock you use.

You will have to connect one display to your hub, and connect the other one directly to a different port on your macbook. Currently there is no way around this.

I believe this is a limitation of MacOS. https://discussions.apple.com/thread/7866674?start=0&tstart=0

If you want a 2nd extended display you'll have to connect it directly to the MacBook.

I'm wondering if the vertical Hengedock will remedy this. It looks like it uses two of your USB-C ports, versus one on most docks, and provides two USB-C ports. I think you could run one display from one of the ports and then connect a traditional dock to the second port (and connect the second display to the dock). When you wanted to dock your MBP and use multiple displays, you would just slide it into the vertical dock and everything would be connected. If you were going for convenience versus cost this might be the best bet. Plus I think the vertical docks look nice and save some space on your desk.

The only bummer is that vertical docks for the newest MacBook Pros aren't shipping until November.

macOS only supports multiple displays out of one output port if one display is a Thunderbolt connected display.

To connect two external non-Thunderbolt displays, you need to use two physical connections to the Mac.

As benboy12 says, a Henge dock would work, since it connects to two ports at once, but the Thunderbolt 3 versions for the current MBP won't be out until November.

Maybe the design of the new Henge dock will be different because it only has to support two standard ports now, but previous reviews for older Henge docks have been little short of awful.

Technically, you could run an eGPU right? I mean, a single TB3 cable to the eGPU then DisplayPort cables from the eGPU to the displays. That's work and only be one connection.

At least, that's what I intend to do in the coming months...Hopefully when VEGA comes out...

With a Thunderbolt-equipped system, yes.
