Hi,
I've got an ibook, and i know that its possible to plug a monitor into it.
At first i thought this was just so that whatever screen was on the macs lcd display would be duplicated on the second monitor, but having discovered some stuff about my PC, i wondered if i would be able to plug in a second monitor to the mac and have it be an extension of my desktop, not just a duplicate?
i downloaded some software, 'screen spanning doctor', but haven't yet installed it, i thought i would find out exactly what the score is first.
thanks alot for any help!
Jonny

there is no way to actually span the screen like you can on a powerbook, natively the ibook only allows you to mirror the image.
the hack that you've downloaded allows you to get around this issue.
while i haven't tried the hack myself, from what i understand it allows you to do the screen spanning. i think it splits up the v-ram so you have 16mb dedicated to one monitor and 16 to the other (assuming you have a 32mb video card). also this is purely speculation on my part but i thought i heard you may run the risk of damaging your monitor as well.

please someone correct me if i'm wrong. hopefully someone else will throw in their .02cents :black:

I have been using the spanning hack for about 6 months, running the iBook display at full 1024 and a Viewsonic CRT at 1600. Not a single problem thus far.

what model ibook do you have? If you have the 8mb video memory one, i don't reccomend you install the hack. 4mb of video per monitor won't get you decent results...

So does this hack allow you to increase the resolution on the second monitor? I was under the impression that the iBook (G4 Nov 2005 model) could only output 1024x768 on either the TFT or any external monitor.

Interesting....

You can't damage the monitor.
In theory you might be able to damage your graphics cards - but nobody has yet.

You should be fine.

The hack allows for much higher resolutions on the 2nd monitor than the ibook's native. It is a great tool. I've been using it since I got my ibook about a year ago.

uh, I know this is kinda old, but.... does this allow you to have more than one "screen" ala linux/unix style?

edit: and display one "screen" on one monitor and the other... on another monitor?

Desktop Manager can simulate more than one "screen". It's a very useful app that is totally free of charge.

Although, after reading over your post one more time, I'm not sure if this is what you meant, but I'll leave it up for it's a very useful app. :mac:
