I have two monitors working in extended view perfectly. I have a need to have both monitors show the same display. My Windows 7 will not offer to "Duplicate this Display". Is this because I need to update my drivers? Or possibly because the screens are a slightly different size. I tried changing the resolution so that they are exactly the same, but I still can not duplicate the screens.

This question came from our site for power users of Apple hardware and software.

This is clearly not a Question associated with Apple. You better ask at SuperUser. –  napcae Feb 11 '14 at 10:30
