Firstly, I know nothing about computers so please explain as clear as possible. I get the message "You are not currently using a display attached to an NVIDIA GPU" when I click on the NVIDIA Settings, so I guess my graphics card isn't working? Does anyone know how I can fix this? I have a Dell XPS17.
Do you have the monitor connected to the Nvidia GeForce GT 555M or the onboard computer graphic connector? Sounds like Nvidia is saying connect the monitor to the GeForce card.
