My laptop has a HDMI port and a VGA port. I've connected an external monitor using the HDMI. I have a GeForce GT630M 2gb video card and Intel HD Graphics 4000 as the onboard graphics. I'm just wondering, when I start to play a game with the external monitor connected, which graphics processor is giving me the output? The Intel or the nVIDIA? Do I need to connect my external monitor with a VGA cable to utilize my 630m? This all might sound dumb, but I got really confused when I saw this in the nVIDIA control panel.. http/imgur.com/ZjVdAei
