So I got a Samsung computer 4years ago when I was in Korea. the spec of this computer is i5 6400, gt 730. I'm using the gt 730 for two monitors. but I got curious about i5 6400 graphics... but can't see the intel graphics driver in device manager, and the driver installation program cant find too... if i put VGA cable to the motherboard port, it is not working too... what should I do...
