I've used this Dell USB-C to HDMI Adaptor and it works perfectly with the 4K monitor at 30hz I've got a work.
I'd really like to try the http://minix.com.hk/en/products/neo-c-usb-c-multiport-adapter. They have a forum post maintaining a list of compatibility and it lists the Yoga 900 which is a good sign. However, I believe I've seen a post somewhere which says not only does the device get exceedingly hot and all the way draining the battery - it would be greate to find some confirmation of this.
If I swap to something that I discover works I'll be sure to report back!

I've contacted the ArcHub people to ask them how they accomplished their testing using one port, and allowing for video out, charging the Yoga, etc. Waiting on a response.

All of my laptops have had a charging port that never did anything else, so that's how I have to think of this one.. a charging port that doesn't do anything until you're on battery, then it's a bonus thumbdrive connection. It's as if that was GOING to be a barrel connector and somene said, "You know what we COULD do..." I'm only sad in that I have about a dozen obsolete Dell laptop bricks. My wife still uses her Dell, so at least they'll see SOME use.

I confirm that above adapter works fine on YOGA 910

marcoferro, I've heard that the minix adaptor would work but I've also seen reports that it runs incredibly hot and that it drains battery very quickly too. Can you confirm/deny if this is the case?

I have an OWC Usb-c Dock driving mouse/keyboard, sound, ethernet, external HDD dock and a 4k LG display.
I don't know if it's a quirk of the display or the dock, but I had to drop the laptop resolution to 1080p before extending the desktop in order for the monitor to be detected correctly. Once I did both displays set themselves to 4k and work just fine.

Has the new bios had any effect on the two USB C ports' functionality?
Not sure what to make of the last item about X1 monitor issues on the readme:
Changes in this release Version 2JCN35WW [Important updates] 1. Change SMBIOS type 3.0 enclosure type from 0Ah to 1Fh, Notebook to Convertible. 2. Update EC to 2JEC33WW version. [New] 1. Modify thermal and DPTF setting, add quiet mode. a) Enter BIOS setup – this can be done by holding down “FN+F2” keys during system start up or pressing the Nova button when the device is shut down. b) Go to page “Configuration” and change system performance mode to “quiet mode”, as seen in the attached picture. c) Select “Exit saving changes” or in page “Exit” or F10, as seen in the attached picture. System will reboot. [Problem fixes] 1. Enable “USB-Type-C Dongle Feature” for X1 monitor issue.
