Is my video card working?

Question

Iron

I have a built-in Intel HD Graphics in my laptop, and an external Nvidia Geforce (or what is it called?)
As I understand it, they should somehow automatically switch between themselves as needed.
But I have a question - in the list of devices I have an error next to the second card.
And reinstalling the driver doesn't help.
1. How can I understand whether Nvidia Geforce is working at all or am I always using the built-in vidyuhi?
2. Can you tell me how to fix the Nvidia driver?

Answer 1

and an external Nvidia Geforce (or what is it called?)

Discrete.
Most likely, the problem is in the drivers. You just need to reinstall them "otherwise".
Download Display Driver Uninstaller, boot from safe mode, uninstall the driver, boot from normal mode and install a new driver (better than the other version to be sure).

Answer 2

With the help of Iobit Driver Booster, you can get everything right. It's better to have a license.

Answer 3

Maybe the problem is in the BIOS, you need to change the integrated one to a discrete one, you can see everything on the Internet
