T15 with Thunderbolt 3 Gen 2 dock. Display with 3 external Monitors

2021-02-20, 5:00 AM

Hello,

 

Does anyone happen to know if it's possible to successfully display 3 external monitors 1920x1080 active res. across all monitors with a T15 connected to a Thunderbolt 3 gen 2 dock? Currently have this setup but only getting 1 1920x1080, 1 800x600, and 1 1280x1024. There is no option in the display settings that allow me to change the 2 monitors. The T15 is setup with a I7 Processor.

please check this document, It looks like  the dock is not connected to the thunderbolt compatible usb-c port.

Thanks for the info. First is the above question even possible? And what is the correct cable needed to connect the t15 to the thunderbolt dock and accomplish what I'm asking? Seems to be 2 types, standard thunderbolt 3 usb-c, and thunderbolt 3 usb-c with attachment. (Not sure what it's called)

It looks like  the dock is not connected to the thunderbolt compatible usb-c port.

 

This  was the broad hint, that such a setup is indeed possible. It does not work for you yet because your system is not set up properly.

Look at the 2nd  point  in the list ( click on the link and take a closer look at the  picture).  Most likely this is the missing "duck".

 

 

here is also a list of supported video output configurations for all types of docking stations.
