My friend has a laptop and the specs are i7 4th gen 4 cores, 16gb of RAM and a GTX 980M.
He uses an extra 4k monitor as the laptop's display but everytime he plug the HDMI cable in, its main choice of GPU is the Intel discreet one.
So any ideas how to get the cable directly plugged into the main GPU?
