X1 Extreme Gen3 - Thunderbolt3 docking with charge and support for 5k screen

2020-10-08, 9:04 AM

I've just gotten my x1 extreme gen3 and need a docking solution for it.

 

At the same time I need a new monitor to replace my old 2 monitor setup of which one was VGA (1600x1200) and DP (2560x1440) - So looking at 27"-32" at min 4k resolution.

 

I've been made aware that there is far between monitors that can actually power the x1 - 60W that is common is a bit to the low side

 

So two setup:

  1. Thunderbolt docking with support for charging. Even the ThinkPad Thunderbolt™ 3 Workstation Dock Gen 2 is only 65W with Thunderbolt and needs the slim tip for the full 170W. But iscome with the split cable https://www.lenovo.com/us/en/accessories-and-monitors/cables-and-adapters/cables/CABLE-BO-Thunderbolt-3-WS-Cable/p/4X90U90616 so should be the safe solution.
  2. Monitor with thunderbolt and charging (90 W should be enough - with the battery as buffer)

 

 

One of interest is LG UltraFine 27MD5KL-B that supports 94W . But is the resolution of 5120 x 2880 supported - Either directly or trough the Workstation Dock ?

 

Another is ThinkVision P32u-10 that is the only one that mentions tb3

 

Lenovo Thinkvision X1 G2 is a nice looking 4k with integrated camera - But it is only USB 3.1 type C so i suspect that it can only charge at 60W and might not even work as a display and charge at the same tim.

 

Any other good solutions that I've overlooked ? I usually dock/undock at least once a day as I use the same for work and private.

I am sort of looking into this as well. My old Lenovo USB-C Dock Gen 1 provides sufficient power (65W as per spec, I take it) to keep my X1 Extreme Gen 3 going with simple office tasks. As soon as I load it however, the charge level starts slowly falling and the dock obviously cannot keep up. So this works for me for the time being. If I am intending to do heavier stuff in combination with external monitor, I'd just connect the original charger to the laptop in parallel with the dock. 

 

It must be noted that I have the i7 CPU on the X1E. If you are running the i9, you may have a bigger problem, as it comes with a 170W instead of a 135W charger for a reason.... This actually was the primary reason I went for the i7 instead. Did't want to be dependent on even higher power requirements and chunkier/heavier charger for the very rare in my case occasions I'd notice the advantages of the i9.

I choose the i7 over the i9 for the same reason - Reasoning that if it need the 170W PSU the battery run with be signifikant inpackted .... 

 

This samsung will soon be available - Should also be able to charge with 90W and the price is not that bad.

I have a Hyper-Juice 100W USB-C charger. I am waiting for a better cable but will see if that is enough to keep it charged with typical use (the cable i have only supports 45W)
