2 graphics cards, and my laptop uses the weaker?

Hi, I have a Medion Erazer X6603 and there are 2 graphics cards installed. I wondered why playing it despite GeForce 1050Ti no decent graphics have.
In the game menu then under the graphics option, I then found that only the worse graphics card is active, the other was not listed. How can I get my laptop now?

say he should only take the GeForce?
Unfortunately, I have absolutely no idea about Computer and therefore I found no understandable answer with Google.

Which games do you play and in which resolution?

I totally played warhammer

Open the Nvidia Control Panel (enter the icon or search in the lower right corner) and go to "Manage 3D Settings". In the tab "Global Settings" you should be able to select your graphics unit. I myself do not have a laptop, so some things may be named differently.

Now I see that all at once the GeForce is activated
