X1 Carbon 7th Gen and USB C Dock Gen2- 3 external monitors

2019-08-20, 10:48 AM

Hi there,


i have a new X1 Carbon 7th Gen with the new USB-C Dock Gen2. I have 3 Monitors connected with 1680x1050 native Resolution. 

I get only 2 working with this resolution. The third one will only get 576p. No matter if its connected to DP or HDMI. The last one doesnt get the full resolution. 


I made a second test with a Lenovo ThinkVision P27h-10. I dont get it working over DP with 2560x1440 and a secondary monitor over DP. The ThinkVision Monitor falls back to 1920x1080. 


All drivers are installed and the latest firmware of the Gen2 Dock is installed. 


When i have connected 2 monitors to the dock and open the X1, the monitor of the x1 will get 1920 resolution. 

Whats wrong? I cannot belive that this new laptop isnt able to power 3 Monitors with 1680x1050 resolution.

Dear customer,

I'd like you to visit the below Lenovo site to confirm the Display & Video output configurations for USB-C Dock Gen2.
