Hi, i have a Dell XPS L502x, and its meant to be a gaming laptop, claimed by dell. However the screen on the laptop is operating on a standard intel family graphics card, when it has a NVIDIA GeForce GT 525M. I have found that the NVIDIA is operating through the HDMI port, which means if the nvidia is to work i have to get a monitor. I have tested it on a monitor and it was very poor quality, so does anyone know how to make the nvidia work through the laptop's screen instead of having the intel one?
