12" Powerbook with external display?

I have a 12" Powerbook (DVI)

I want to connect it to an external display (probably a 24", 1920x1200).

Will the powerbook be able to support the maximum resolution of this display? As ive seen conflicting information on the net.

Cheers,

Mark.

it says:

Dual display and video mirroring: Simultaneously supports up to 1024 by 768 pixels on the built-in display and up to 2048 by 1536 pixels on an external display, both at millions of colors 8


But will it support the exact resolution of 1920x1200?

The Powerbook is a 4:3 ratio display, and not widescreen, does this affect anything? 2048x1536 is 4:3...
