MacBook + Asus A6000 A6Ja

I’ve got here one MacBook that renders at a good speed but cannot output video, and one Asus A6000 laptop that can’t render steady >60fps but outputs video just fine. Provided that there is not enough time/money to acquire a Mini-DVI to VGA-dongle and a scan converter for the MacBook, is there any way to transform that A6000 into one hell of an expensive video-adapter?
Or, closely related, does anybody know of any special drivers/issues one might have missed on the fresh WinXP-install of the Asus that might prevent the ATI Radeon X1600 Mobility from enforcing her proper renderpower?

edit: the issue has resolved.
