Dual monitor setup problems

[Eric_NY]

I'm having trouble setting up a second monitor with my laptop. It displays
the same information as my laptop screen and I can't get it to work as second
monitor for an extended desktop.

I'm using a Dell Latitude laptop and Windows XP. I regularly use dual
monitors with this computer at my office. Now I am in a different location,
and trying to set up a dual monitor.

The second monitor works fine. But it's working as a mirror display - I see
the same thing on both monitors. I've tried various things .... In Display
Settings, Setup tab, I click Identify and both monitors identify themselves
as 1. Under the Display drop-down, there are two monitors listed, numbered 1
and 2, and both with the identical label (Default Monitor on Mobile Intel(R)
945GM Express Chipset Family). I can see icons for monitors 1 and 2 under
"Drag your monitor icons..." I've tried all possible combinations of "Use
this device as your primary monitor" and "Extend my Windows desktop onto this
monitor". But both displays still have identical information.

I've tried the troubleshoot wizard, but it can't tell me what's wrong.

Any suggestions?

Thanks.

Laptop video cards are extremely difficult to set up. The main
problem is the fact that most manufacturer offer a tool, either
software or keyboard key combo. This tool will tell the video card
what to do, either "clone" the laptop's display or to extend the
desktop. I believe you must disable the display "clone" mode.

Thanks for the tip. I've figured out that Fn-F8 will toggle between the
various display modes, including what I need.

Thansk for your help.
