Hi all - Can someone clear up an issue for me?

I'd like to pick up a 2017 MB - and would occasionally like to use it to drive a 30" (Dell U3014) monitor . The monitor is a little dated, but is still pretty awesome and supports HDMI and DisplayPort.

So my question is - since there's only one USB C port on the MB, if I connect a the Display Port monitor to it via USB-C to DP cable, will that power the laptop? I can drive the monitor with an old 2011 MB Air - and am thinking I should be able to the same with a MB, I'm just not sure how the MB gets power. Or - would I need to use some kind of dock device?

Thanks!

You would need to use a dock or an adapter that allows at least USB-C power delivery to pass through to the machine. The dock/adapter would be plugged into your machine via USB-C, and the DP cable to the monitor and a USB-C cable to the power adapter would both be plugged into the dock/adapter.

That's what I figured - Thanks!
