Yoga 370 & Type C Dock with 3 monitors

Hey everyone,

 

I've been searching high and low for some info.  I have looked to see if I can find some info but I am unable to find a solution.  I currently have a Lenovo 370 with a Lenovo ThinkPad USB-C Dock

( https://www3.lenovo.com/us/en/accessories-and-monitors/home-office/Thinkpad-USB-C-Dock/p/40A90090US ) 

 

Currently I am running into an issue where I can run two monitors (any combo DP and VGA) and they will run at full resolution.  As soon as the third monitor is connected; doesn't matter the combo or how the third is plugged in, it runs at 640x480 resolution and will not adjust to proper resolution.

 

I have run TVSU and all are updated, and even within windows 10 updates are complete.  Intel support shows that the card can be running at three monitors.  I have a T460s as well that can run the three monitors with the Ultra Dock at full resolution so I know it is not a monitor issue.

 

I am wondering is this a limitation of the Yoga itself or is this a problem with the ThinkPad USB-C dock?

 

Any ideas would be greatly appriciated.

 

Thanks!

Would like to know if you ever found a solution. I've run into the same thing with a ThinkPad T580 and the C-Dock.
No matter which is the 3rd monitor added I can't change the resolution, regardless of what port you plug it into.

Very frustrating!

Same issue, only work around I was able to get it to work was to run 2 monitors off the docking station and the 3rd off the HDMI port on the side of the laptop. With that config all resolutions were matched and adjustable.

I ended up using a USB to HDMI adapter for the 3rd.
