How to enable to work only one card on my laptop?
Good morning. I have Alienware m14x with NVidia Optimus GT555M. I would like to be able to have my laptop screen and external HDMI screen both working. Is there any way I can do it? I would prefer to turn off the integrated GPU completely and just let the PC to run on the NVIDIA if possible, but I can't find a solution for that.
Thank you for any tips
