When using Fn+F5 my cards will not switch. It tells me "Your graphics solution is automatically configured for optimal performance". I want to disable the Intel onboard graphics completely and only use my Nvidia card. Right now I don't have any options to even USE my Nvidia card since everything is automatic. 

I have uninstalled and reinstalled dell drivers, I have used updated drivers from vendors sites, I am on current bios for my machine (A09), I have followed the process outlined in another post that says the install order must go: Intel, Nvidia, On Screen Display driver. 

None of them have worked. Please help.
