external display and GPU

Mikes13 · ‎01-27-2020

Hi All,

I have bought an external monitor and I need it to be connected, through the only HDMI port the laptop has, to the dedicated GPU (NVIDIA GeForce 940MX).
Can you please help me? It looks like it connects automatically to the internal laptop's chipset and that doesn't allow me to reach 4k resolution on the new external display.

Thank you very much for your help in advance.

Regards

You can't connect to specific video chips, only to the laptop.

The OS decides which chip handles the video, based on graphics demand -- so you can't use JUST the Nvidia chip.

Ok, how can I make it use the Nvidia Geforce? I want it to full 4k resolution and now it just doesn’t reach it because of the “wrong” GPU

You simply may not be able to do that. Some PC BIOSs allow you to disable the built-in video chip; others do no.

If you go to Nvidia, they have drivers and utilities you can download. You might be able to FORCE usage of the Nvidia chip using one or more of those.

Good Luck
