I am looking for a dock for my new tablet that will run 2 4k monitors. I already have a X1 Extreme with the Thunderbolt 230 watt workstation dock that I have tried, I am able to get one monitor working at 4k, the other is limited to 1080p. Also, the tablet won't charge hooked up the dock without the A.C. adapter. I have tried both passive and active Thunderbolt cables with no luck (6 ft cables).
I would have expected that the X1 tablet would support 2 4k monitors but maybe I am doing something wrong? Is the 6ft cable length the issue even with active Thunderbolt cables?

Welcome to the Lenovo forum discussion!
As we were checking here, we have found a 2 docking stations that can support dual 4k display.
ThinkPad Hybrid USB-C with USB-A Dock (American Standard Plug Type B) - https://accessorysmartfind.lenovo.com/products/40AF0135US?CID=ww:lenovosocial:20x9m6
ThinkPad Thunderbolt 3 Dock Gen 2 - US - https://accessorysmartfind.lenovo.com/products/40AN0135US?CID=ww:lenovosocial:20x9m6
You can try the docking station that you preferred from here https://smartfind.lenovo.com?CID=ww:lenovosocial:20x9m6 (click on Accessories). Let us know if you have any other concern.

So after researching a lot, the USB-C Dock is not well liked due to limiations of USB-C compared to Thunderbolt. I was tempted to try the Thunderbolt 3 Gen 2 but wanted the extra graphics card option of the Lenovo Graphics Dock. The Lenovo Graphics dock is not advertised to support any laptop except for an Ideapad? Anyway, after reading other posts I was convinced it would work for me so I ordered one.
Works perfectly so far! I have it connected to two 27" 4k monitors and both are running as they should be. The tablet is charging from the dock (I am not using the tablet's adapter).
The driver install was easy. Lenovo vantage is saying there is a firmware update but it won't complete. Since everything is working, I will circle back to that later.
I loaded up my Steam account and played some Super Mega Baseball 2 and the game played very well at 1080p. I will try a higher resolution later.
The tablet is going to be my work from home/use around the house machine and I will save the X1 Extreme for games and more CPU intensive stuff.
I don't know why Lenovo doesn't officially support more laptops with this dock.

Hello. I just purchased an x1 gen 2 tablet. Do you know if the graphics dock will work? Just to be clear, I assume the g-dock is this:
Thank you for your time

Hi trying to revive this old thread.
I was wondering if USB type c multiports can't be used to connect to 4k monitors/or any monitor. I used two kinds of USB type C hubs and none of them worked for my X1 Tablet 3rd (although they worked nicely for my MacBook). Should I use Lenovo USB-C Travel Hub instead? thanks
