I'm using Windows XP. My laptop is not showing dual monitor properly. I want the screen on my laptop and on the projector mirrored.
I right click on Desktop, Properties and then Settings, "Show two Computers" – OK.
When I hit Ctrl and F8 (the CRT/LCD switch) and select the middle option ("two monitors"), the projector shows a blank screen, which is actually the extended desktop as I can move my cursor from my computer to projector screen. The same way I can a drag file from screen 1 to screen 2.
This causes a problem. It works okay when I use PowerPoint, but not when I demo some software. In PowerPoint we can select monitor 1 or 2 from drop down.
In display settings for monitor 1, both "Use device as primary monitor" and "Extend my Windows monitor onto this monitor" are grayed out and checked.
For monitor 2, "Extend my Windows monitor onto this monitor" is unchecked.

Usually cycling through [fcn]+ F8 (or F7 depending on the model of laptop), should go through the options for the sVGA port.
You should have (at least) Laptop only, Laptop & External, External only options.
