@JONIME
Welcome to the HP Forums 🙂
I would like to take a moment and thank you for using this forum, it is a great place to find answers.
As I understand you need assistance with a dual display setup and I'll be glad to help,
However, I need a few more details to provide an accurate solution:
Have you ensured both cables (DVI & HDMI) are working on alternate products and if the monitor is powered on and working?
Is this your first time setting up dual display or have you been there, done that? 😉
Did you install the latest drivers for both your Nvidia graphics and your alternate monitor?
In the meantime, Please follow the steps mentioned below:
