Set the Initiate Graphic Adapter to IGPU, turn off your PC, plug in your video cable, restart your PC. That should do it.

If you get it working, install the Intel driver, so that you can use the Intel Graphics and Media Control Panel.

You don't need to remove the graphics card, as it goes into the idle mode, when the IGPU is selected in the BIOS.
That's what I didn't do. I will give it another whirl.
