We have a 1Ghz Titanium PB with the ATI Mobility 9000 (64 Megs VRAM) and DVI port.
The specs say that it can handle resolutions up to 2048 x 1536.
But I assume that is talking about a single monitor with the PB lid closed.
What if we want to use extended desktop with an external monitor and the PB open?
I'm thinking about a 20" @ 1600x1200 plus the built-in screen @ 1280x854(native)
