How to choose default graphic card (HP Elitebook 850 G7)

[PetrSkiwi]

Hello to all, I just struggling with issue that I am not able to force my notebook to use Nvidia GeForce MX250 graphic card as default one. Instead of this - Intel UHD Graphic is used. I am using with my notebook docking station HP USB-C Dock G5 and if I need to connect 3 monitors one of them stay in low resolution. So my opinion is that Intel UHD is not able to work with so many monitors, but system is not able to switch to GeForce card automatically. I tried almost everything:  

- Change graphic card in Nvidia setting in Win10

- Disable Intel UHD in device manager

- Force to use Nvidia card in BIOS

- Reinstalation of Win 10

- All drives are up-to-date

Before Elitebook 850 G7 I had Elitebook 850 G5 with graphic card RX450 and everything worked well - same system, same monitors

@PetrSkiwi,

Welcome to our HP User Forum!

Have you adjusted the 3D setting in the Nvidia Control Panel ('Preferred graphics processor') as shown here: How to Switch Between Dedicated GPU and Integrated Graphics (helpdeskgeek.com)?

Yes I tried this option. 

But then when I go into the screen setting and choose one of the monitors, in advanced screen setting I see that still Intel UHD is used for display. 

I also tried to change PhysX option from Intel UHD to Nvidia, but it doesn't work.
