Two weeks ago we purchased 3 "Thinkpad Pro Docking Stations" from Lenovo.com, PN 40AH0135US.
The back has two DISPLAYPORT ports on the back. However, we have not been able to get dual monitors to work. My question is this: will this particular docking station even support dual monitor displays?
When I called Lenovo support thw two techs I spoke with couldn't even find our "FRU P/N" that is listed on the docking station so they said they can't pull up documentation or help me. Evidently this product is too new for Lenovo support.
Does anyone else know if this docking station will support dual monitor displays utilizing the dual display port ports in the back?

Q: Will this particular docking station even support dual monitor displays?
A: Yes, it supports two external DP monitors with max resolution up to 4096*2160@30Hz. Moreover, if you connect one external DP monitor, it supports max resolution up to 4096*2160@60Hz
I've tried it in person that both of my monitors successfully got a resolution of 3840*2160@30Hz, which is the max resolution to the monitors.
If your dock doesn't work like mine, it is recommended that you download the Firmwares and Drives at the site below:
Hope this helps.

I am currently using a pair of DP monitors via the Pro Dock (40ah - side dock). I am able to run 1920x1200 @60hz on both monitors. No 4K monitors tried yet.
My laptop is X1 Carbon 6th Gen 20KG (Costco version)
My dock is Thinkpad Pro Docking Station 40AH.
I have a different issue regarding the dock. The problem is this:
When the laptop is DOCKED (and only when docked) I cannot get the laptop to sleep or turn off the displays on it's defined schedule in Windows power settings.
What does work: It will sleep on schedule when on undocked; both on battery and when using the charger. And I can also MANUALLY put the laptop into sleep from the Windows shutdown menu. The problem only occurs when the laptop is DOCKED.
I have updated to the latest dock drivers and firmware (6.3.9600.127 as of today 4/28/18). I'm using the default "Balanced" power settings.

Thanks for your sharing.
According to your description, it looks like the issue was caused by Windows.
Anyway, it's great that the issue has been fixed.

Sorry, I don't use blogs/communities often. Business laptop, just went from T420 to T470 and jumped form WIN7 to WIN10, on the new T470 the pointer is great on the outer file menues and scrolling for most applications, but for a couple of my applications when I am inside the fields and icons, the pointer is off by about 1". (If I want to click on an OK button, I have to have the pointer 1" to the right of the OK button). THis is the same whetehr the track pad or mouse plugged into docking station or Laptop
When the T470 is not on the docking station, it works fine. Does not happen for normal applications liek Word or Excel, but a company specific applications.

I bought a Thinkpad pro Docking station (Part number: 40AH0135US) a couple of months ago to use with my Lenove Thinkpad T480 and 2 external monitors with HDMI ports. Connected the HDMI ports on the monitors to 2 display ports on the Docking station (had to use a converter to convert HDMI cable to plug into Display ports on the docking station). Laptop has Windows 10, 64 bit. I could not get the monitors to work correctly. Only one external monitor would work at a time or not work at all. I tried changing out HDMI cables but that did not help. Came across this post and checked the firmware on my Docking station. Followed the link to see instructions for upgrading firmware for Docking station. I upgraded the firmware to the latest that was availale on 5/15/2019.
After upgrade this is the version that shows:
USB HUB = 5043/5033
Everything is now working as it should. 2 External monitors are working correctly.
Thank you very much.
