since I received several questions concerning this topic, I had to search for answers.
I think it will be helpful for people looking for answers too on some of these features.
There a couple of Lenovo Displays have USB-C support, and are even able to charge your Notebook!
These are current ThinkVision Monitors that have USB-C (new models are coming sooner or later, so this might be incomplete):
There are some limitations to keep in mind though.
Here are the details I found and tried to consolidate.
Please feel free to add your input as a comment below (this list is by no means final and complete, and there are always new models coming, that I have not tested or not received these infos yet)...
General Power Limitations:
|USB 1.0/1.1||5 Volt||0,1 A||0,5 W|
|USB 2.0||5 Volt||0,5 A||2,5 W|
|USB 3.0/3.1/3.2||5 Volt||0,9 A||4,5 W|
|USB-BC 1.2||5 Volt||1,5 A||7,5 W|
|USB-Typ-C||5 Volt||3 A||15 W|
|USB-PD||5 - 20 Volt||5 A||100 W|
This means, if your Notebook has a power supply less than 100W, PD should be possible.
Most ThinkPads come with 65W or 90W PSUs. The more powerful models (like P71 and P51) have 130W or bigger PSUs, and therefore need to much power... you can't use PD with these models (see table below).
Tested current models (new/other models not tested yet):
X1 Carbon (14)
X1 Tablet, Core i
Yoga 370 / S1
X1 Tablet, Core m
E570 / E575
E470 / E475
11e / 11e Yoga Chrome
I don't have time to update this list regularly, so it migh be obsolete at one time in the future.
But as long as people add there insights, it can be kept alive...

I Post the answer to your question here, because I have reached the limit of private messages I can post today...
The datasheet seems to be an official one, though the source isn't...
But to answer your question:
There are several accessories you can buy, that work with the chromebook.
You can find these options easily here: http://accsmartfind.lenovo.com/search?systemId=88ELC1S9999&query=&pageSize=40&pageIndex=1
Just search and filter for the items you need...
We also offer a USB-C to DisplayPort Adapter, but it is not listed as tested with the unit... so I can't gurantee 100% whether it'll work.
Sorry for that. I think it might work, at least I don't see a technical reason why it shouldn't, but it's not guranteed.
Maybe someone else has tested it?! Try posting this as a question in the forum!
Lenovo USB-C TO DISPLAYPORT Adapter 4X90Q93303
Sorry that I couldn't solve this one on the fly...

I hope you understand that we can't speak for other brands and products. Only for our own...
So even if it's quite probable that third party adapter will work, we can't vouch for the quality or full functionality of untested 3rd party options.

I just looked up the official setup guide for the USB-C dock ( https://support.lenovo.com/de/de/accessories/acc100348 ).
On the website there is a link to the setup poster: Setup Poster and Warranty Information
Step 2 of the description shows the port to charge your notebook/tablet (the USB-C port next to the power supply port).
The port should be able to charge units with up to 60W (even though the PSU is 90W).
On the front of the dock, there is another USB-C port and a powered USB port.
These two ports are limited: 15W and 10.5W from the USB-C port and USB 3.0 always power on port respectively .
If that doesn't work I'd recommend a hardware reset, and/or contacting the official Lenovo support.

Hi, just wanted to confirm the compatibility of my x270. I am thinking of getting an external monitor, Asus MB169, which uses a usb c connector. Will that work with the x270?
