Kali not using GPU as primary display driver with drivers installed

Hi!

I recently got into Kali and im a amateur at, working with Linux and stuff like that! So my problem is I installed the NVidia driver for my gpu(GTX 750 Ti) but if i plug the hdmi to the gpu, i get no signal(currently im using integrated). Also I have another monitor thats because i need the gpu to be the main driver.

Thanks!
