Today I noticed the same issue with driver 331.40 which I then updated to 340.52 and that didn't work either. I went back to 320.49 which works fine.
For me windows+P extend shows only center screen active and others disabled. Display config shows only 1 monitor selectable. Driver 320.49 shows 3 monitors you can enable and disable as you wish.
I'm looking for next generation of nvidia cards for more power but the nvidia drivers seem to get worse and worse every version feature wise. Is AMD better drivers wise these days than it was few years ago pretty crappy?
edit: I had a look on nvidia's forum and found similar issues. Apparently this bug may be working as intented but there's a workaround:
Quote:
This isn't a total fix, but it's as close as I could figure out.
-Set up an Activate/Deactivate Surround keyboard shortcut within NVIDIA Control Panel.
-Configure Surround Spanning. Test your keyboard shortcut. *If it doesn't switch, see the next group of instructions.
-For me, deactivating would result in only one active monitor, so
-Now press WIN+P, click EXTEND.

Now all I have to do to activate is:
CTRL+SHFT+S.
To deactivate:
CTRL+SHFT+S, (wait), WIN+P, click Extend.
