Hi All,

I have an Inspiron 9300, running Windows XP, set up to use an external
monitor as an extended desktop. This works fine.

My problem is how to switch off this feature !

I use the laptop for presentations and, therefore, I need to use it
with an external projector mirroring my desktop from time to time.

The darn extend option just won't switch off !

I get rid of the tick in Display Properties and it puts it straight
back as soon as I try and toggle the projector on using the laptop
keyboard control.

I guess I must be doing something silly here but I am mystified as to
what.

Can anyone make some suggestions ?

Many Thanks

Neil

Right click anywhere on the desktop and select the 'settings' tab on the box
that appears. Left click on the monitor with '2' in it and then uncheck the
'Extend the windows desktop onto this monitor'. Press 'Apply'. The
displays should mometarily black out an then come back on the primary
monitor only.

Thanks for this.

I am afraid I have tried this already. See my original note.

Any other idea ?

It most certainly shouldn't stay in this mode if there is nothing connected
to the extra output. My feeling at the moment is that the graphics
circuitry has sustained some hardware fault, but software can't entirely be
ruled out.
