Multiple Monitors for iBooks

  1. Is it possible to do the "reverse" on an iMac by automandc · · Score: 4, Interesting

    In the same vein, does anyone know if it's possible to use the built in LCD panel on an iMac as a monitor for a different computer (i.e. a "video-in" for the iMac monitor)?

    I realize that it is probably a hardware hack, but if anyone has ever done this I'd be interested to hear. One of my major reasons for not getting a Mac is that I can't justify (afford) a G4 standalone, but I don't want two monitors on my desk unless I can use both of them simultaneously.

  2. Re:Get your terminology right by Steve+Cowan · · Score: 5, Interesting
    The problem is that "multiple monitor support" is an ambiguous term. The iBook has multiple monitor support - you can plug in a VGA monitor and have it display the same thing that's on your built-in display. In Apple parlance it's mirroring, but technically it is still multiple monitor support.

    On their web site, Apple has referred to monitor spanning as both "extended desktop" and "dual display".

    Now I just wish somebody could come up with a hack for my RAGE iBook 500.

  3. Quartz Extreme probably won't work by drsmithy · · Score: 4, Interesting

    Be aware that using spanning will disable QE. Assuming the iBook is like my (Rev A 667) TiBook, when display spanning is used the 16MB of VRAM on the chip is split into 8MB per display, which isn't enough for QE.
