You sure this would even work? I used Nvidia inspector (basically "Nvidia control panel advanced - use at your own risk") and tried ALL the options, and it would still use the intel card.
Optimus/switchable graphics is a little more complicated than "2 video cards." Assuming ducks has the same setup as my gaming laptop, it still uses both cards even when you're running a game through the Nvidia card. This is basically how it works:
Game -> sends instructions to Nvidia card -> Nvidia card performs calculations -> the result of the calculations is passed to the intel card -> intel card draws the result onto the display.
This is why his screen stops working when he disables his intel card. There's no way to bypass it, because the monitor is not connected to the Nvidia card at all. The Nvidia card has to pass the final result to the intel card, which draws it on the screen. It's not the same as people who run multiple video cards in parallel using SLI. It's a fucking Frankenstein of a video card system, and the drivers are Frankenstein'd together as well. They're shit.
