Connect nvidia graphic card in T470p laptop through Ultradock 135W

2018-02-09, 18:33 PM

Hi,

 

I got a T470p laptop and a Ultradock 135W. I noticed the external displays aren't connected to the nvidia graphic card when I connect them through the Ultradock.

Can the external displays be connected to the nvidia graphic card through the Ultradock?

Are there any settings that can fix this?

Solved! See the solution

AFAIK, currently only P-series laptops have output video ports connected to discrete GPU. You can switch between GPUs in BIOS. Starting from T440p, all outputs were wired to Intel GPU. Both cards can only work in NVIDIA Optimus setting. It's not possible to change it.
