Dear Sir,
Please kindly be informed that I have an Alienware m17x R4 with the Graphics card GTX 680m and it is running Windows 8.1 64 bit.
Now in the device manager both my integrated graphic card HD Graphics 4000 and GTX 680m are shown under the display adapters.
I want to work only with the GTX 680m only but unfortunately the Fn+F7 does does do anything. I even installed both the on-screen display driver software from Dell support page for my laptop and Alienware Command centre but unfortunately no luck. I even updated the framework 3.5 yet the fn+F7 does not work at all. I uninstalled the graphic driver from the device manager and did a clean installation yet not luck and the fn+F7 does but work whatsoever.
Please kindly find my service tag below for your kind reference:
<ADMIN NOTE: Service tag removed per privacy policy> (M17xR4)
And the Express Service Code:

I am looking forward to receiving your answer soon.
Best regards ,
