Hi, I own a Dell M3800 laptop that has a discreet NVIDIA Quadro K1100M graphics card. In LR preferences the menu related to graphics card acceleration only sees the Intel HD 4600 that is integrated on the motherboard. I have tried deactivating the Intel graphics but even then LR cannot see the NVIDIA card. Has anybody managed to do this?
You will be better off turning the Use Graphics Processor option off.
It doesn't work correctly anyway so no need to fool around with disabling the Intel graphics.
