X1 Carbon (5th generation)-TV-P24H-10-Thinkpad USB-C dock type 40A9

2020-02-04, 17:09 PM

Hello All, I have set up this combo of devices, and the external monitor flickers on and off sporadically using a DP cable.  I used this with an older monitor and it functioned fine, however I purchased 2 24 inch and it will not work.  Either monitor functions perfectly fine plugged into a different computer so I doubt it is the monitor. My wife is able to use her Dell laptop with my Docking station.. it works fine.  I have updated everything there is to possible update on the X1, Updated everything on the docking station, and downloaded a new .inf file for the monitor.  Does anyone have any ideas?  Both monitors are detected, just flash constantly.

Hi AHJax!


Welcome to our forums community.


Have you tried connecting the external monitors directly to the laptop via HDMI or Thunderbolt-C port to check if it works? Could you send to us the system information on your laptop? Type msinfo on the search box at the bottom left side of your laptop. And also, what is the current driver version and firmware version of the docking station? You can update it via this link: https://support.lenovo.com/us/en/solutions/ps500292.


Let us know how it goes.
