From what I've read, I can see that a Powerbook's available VRAM will split between the built-in display and the external display when an external display is attached. Here's my question though: Will the external display use all of the available VRAM if the Powerbook is run in lid-closed mode?
Got a tip for us?

How do you do that with only one DVI port?Chef Medeski said:
I was playing today and splitting the 64MB card between the two displays (inbuilt and 20"ACD) works wonderfully. You get all the eye-candy goodness (like the ripple effect etc on both screens) and there doesn't seem to be any noticeable slowdown. I'd imagine the 128MB cards would drive the displays wonderfully though
.
There's also a PC Video card that has DVI output (even dual DVI outputs) so you can add 1 or 2 LCDs to the powerbook, in addition to the DVI out. I forget the link, but it uses a card with 32 MB video memory.

FYI, here's a review (as I have no idea whether it works as advertised):

Ohhh thats a bummer. The only good aspects of a Powerbook aren't available on a 12", that really sucks. But probably udnerstandable considering their size. I don't know if they have room to fit much more without it overheating.

Apple do sell a mini DVI to Video adapter at the store that will do that though. It's mini DVI to composite or S-video
edited as I was totally wrong about there not being a powerbook adapter

Can you run clamshell mode with the hack on an iBook? Because with my powerbook I can start the clamshell mode, give all the VRAM to the external display, then lift the screen on the powerbook and it will stay completely black and turned off. If you can run clamshell, I don't see why this wouldn't work.
