Bootcamp - External Display not functioning

[fivepoint]

I've got a 20" external Dell LCD monitor running off of a new White Macbook. When in Mac OS, the display works perfectly. However, when rebooting in windows XP all I see is the OS loading screen before the display goes black and nothing ever shows up.

I've got the monitor connected via mini-DVI to DVI connector. If anyone else has come across this problem and can suggest a possible solution, It'd be very much appreciated!


Additional Info

Have you changed the settings in the appropriate dialog?
(Control Panel > Display > Settings > "Expand Monitor to second Display" or something like this)

Windows XP is not that fluent with detecting an extra monitor.

Have you go the latest Windows drivers for your graphics card?
