So basically what I'm trying to do here it use my laptop as an extended screen to my PC. However I only have 2 HDMI ports, the first is the port of my GeForce GTX 770 and the other port is my integrated Intel HD graphics. So all I SHOULD have to do is plug in the HDMI from my laptop to my integrated Intel HD graphics port, but it's not being detected at all. According to what I've read, I need to enable the Integrated Graphics in BIOS but the option isn't there for me . Some help would really be appreciated. Thanks!
