how does the mac mini run a 20" display and a powerbook doesnt. It must be really slow and laggy? even if you have the ram maxed out how does the graphics card pull that off?

You can find it here.javiercr said:if you want to use the lcd and a extermal monitor for monitor spanning with the ibook you need the dual monitor hack (seach google) the limitation in the ibook is not technological is just to create a bigger gap with the powerbook.

is it possible to EVER split a dual-link DVI into 2 separate standard DVI signals?

No matter what, it cuts your VRAM down to 16MB on the external.

cbiffle said:That's not entirely accurate. VRAM can be shared between the displays for a lot of things, like OpenGL textures (used for font rendering in Tiger).
I'm not up on the recent ATI architectures, but last time I was writing drivers for this sort of thing, screen spanning created a giant logical screen and displayed parts of it on both screens. Meaning, buffer area is split depending on the size/depth of the displays, and non-buffer data (backing stores, textures) is shared.
What do you mean exactly by 'graphics performance' ? Are you talking about frame rates in a game like Doom, or playing movies?powerbook911 said:I'm just saying even if you turn off the LCD on the iBook, you're still limited to 16 MB of VRAM according to the system profiler, and I sure felt it! I had only a 15-inch LCD connected to the iBook, when I owned one, and the graphics performance was not very good.
