physicly i had 2 GPU. i have a randeon and then i have the basic intel one on my motherboard. so people in the future that are reading this, MAKE SURE THAT YOUR MONITOR IS SET-UP TO YOUR GAMING GRAPHIC CARD PHYSICLY. your graphic card from the motherboard or singular graphic card, both have physical connection (HDMI,DVI, and others) you need to connect your wire from monitor to the right physical plug-in that is aimed to the graphical cards.
thank you Atic to make me realise that i didn't use my gaming graphic card in months XD
