But the Dell forums answer this one a lot. Example at:

Hey guys I'm just looking for some help. My Dell Inspiron i17rn 3530dbk has a built in Intel graphics card, and also a Nvidia Geforce 500 series graphics card. The default one being used is the intel graphics card, and I'd like to change it to the nvidia one. I can't find anything online on how to do it, and I can't figure it out by myself. I'd appreciate a little help on this. If you need any more info on this, just ask, thanks in advance guys.
