I have a new Dell G3 laptop with an NVIDIA 1060 TI gpu. This system is set up for dual boot with windows/ubuntu. Ubuntu can't detect the HDMI port and doesn't show my second monitor. However, it works well with windows.

I've tried installing all of the routine updates. None of these things fix the problem.

I also recently change my driver with this commnad:

sudo apt install nvidia-driver-435

but it didn't solve the problem.

$ lspci -k | grep -EA3 'VGA|3D|Display'

TL;DR its probable that the nvidia card is not turned on. This is definitely the case for my Dell Inspiron and my wife's G3. The HDMI cable is controlled solely by the NVIDIA card
