How to change AMD R7 M445 videocard as default instead of intergrated Intel HD graphics

I have a Dell inspiron 17 5767 with an AMD R7 M445 videocard, but when I want to play a game and the videocard should start working I have the idea that I'm still gaming on Intel's HD graphics. I looked it up in dxdiag and that shows this:
