As the tittle, my laptop owned two graphic card. One is Amd radeon R9 M280x and one is R7 Graphic, i checked my Radeon setting and it show that Radeon R7 graphic is the primary Graphic card while Radeon R9 M280x is the Linked graphic card. I would like to ask how to change my Radeon R9 M280x to primary graphic card instead of Radeon r7. Thank you
