Dual Monitors - displaying duplicate desktop.

Hello all,

I currently have Windows XP set up to use 2 monitors.  Works perfectly fine.  I have one as my primary and the other as an extended desktop.  

But I occassionally want both screens to display the exact same thing.  How would I get this to work?

1/2 question followup.  My Home laptop running the same OS is the same thing.  Can only display second monitor as extended rather than duplicate.

Uncheck the "extend desktop" checkbox in display properties, and it should become a cloned display.
You will need to set that option in your video card software. Windows will only handle extenting the desktop. Nvidia and ATI for example have the option to clone the display but the option is only available in the videocard software. What video card do you have in both?

I've tried, the 2nd desktop just becomes blank.

Radeon X300 in my PC.  I believe the same one is in my Laptop?  Will have to verify that when I get home.
