Quick question... probably easy
If I wanted to use an external monitor--20" apple cinema display with 1680 x 1050 res---for a 12" PB with 1024x768 resolution, would that be possible? If so how? Thanks everyone |

Yep. It's officially supported according to Apple. Your 12" PowerBook should have a mini-DVI port and an adapter to let you use a DVI monitor on it. Just plug the display's DVI cable into the PowerBook's DVI port and it should work. You can configure the two displays (positions relative to one another, resolution, etc) using System Preferences. It's handy, when you have either "Desktop" or "Displays" open, it'll pop up another window on your secondary display to let you adjust settings for it.

Possible. Just plug it right in to anything in the powerbook line, and it will work. Im typing this on a Gateway EV70 @ 1280x1024 connected to a 12" powerbook.
Hope this helps. EDIT:Im a slower type than Luca, so this post is redundant. What's the difference between a Democrat and a bucket of crap? The bucket. |

Thanks, I'm glad to know that it's possible...
But I'm still confused, how can the hardwar/video card in the PB display a higher resolution than it is capable of displaying on the PB screen itself? |

Because that's how video cards are made. You can switch resolutions, right? You can run your display at 640x480 or 800x600 if you want. Or look at the 15" and 17" PowerBooks. They both use the exact same video chip, yet the 15" runs at 1280x854 while the 17" uses 1440x900. Video cards are simply designed to be able to drive displays at just about any resolution possible. Even old ones can run a 1600x1200 display. Take any $30 off-the-shelf video card today and I guarantee you it'll support a resolution up to 1920x1200 or something crazy high like that.
EDIT: Yeah, what BlueRabbit said. The 12" PowerBook uses an LCD that has exactly 1,024 columns of pixels and 768 rows of pixels, so you can't physically display more pixels. CRTs don't use physical pixels the way LCDs do, so you can display very high resolutions on CRTs. |
