Question : Problem: Toshiba P105-S9312 w/ NVidia GeForce Go 7900GS  -

lost the Fn5 hotkey to send display to external video projector, fiddled with using the Nvidia settings,  cant see display on both Laptop and  video projector.

I would also like to know how to set the hot key combinations so I can toggle from the laptop only to seeing the same display on both the laptop and the video projection.

Projector is a Dell 2300 MP using the serial out port
XP Pro

Answer : Problem: Toshiba P105-S9312 w/ NVidia GeForce Go 7900GS  -

I've tired the download Hot key update, which failed to re-enable the Fn 5 toggle to external video projector.
After messing with the Nvidia Control panel, (which is complicated and at times confusing) I did manage to find/make a configuration which allows me to display the laptop screen on the video projector at the same time.  It appears to be called a "clone" display...

So, we didn't actuall return the laptop easy button hotkey, but did figure out how to make a work around instead...pity it proved so frustrating...

Thanks for helping anyway.
