I set my TV to 'extend' my laptop screen and to be the primary display, but the TV won't display the primary duplicate display - I'm left with a laptop which just shows an area of blank screen.

I can't change the setting away from duplicate as I cannot see anything on the laptop. If I right-click and select Catalyst Graphics Software, it appears where the TV should show it.

Any ideas how to fix this? I want the TV to only show what is on the laptop, not to extend the screen.
