Hi, I have a MSI GT780 (Not a DX or DXR), and I'm trying to upgrade from my old GTX560M to a 770M. I saw Bugii's post that for the GT780DX it should essentially be plug and play. I have a new 770m(I made sure its the Clevo model), and after installation the laptop boots up, and I can hear the windows sound play, but I have nothing but a black back lit screen. Is it a difference between the GT780 and 780DX that is causing my issue? Do I need to update my video drivers, and if so is there a way I can do this blind? This is my first time replacing a video card so any help is appreciated.
