iBook G4 ADC Display?

The first thing you'll need is a Dr. Bott DVIator or Apple DVI/ADC adapter in order to convert from DVI to ADC (and power the display). Secondly you'll need to find some way of converting the iBook's VGA signal to DVI...while I seem to recall that there are VGA -> DVI converter boxes, they are neither cheap nor easily available. You'd be much better off just buying a cheap VGA LCD.

Not worth the cost.

If you had a PowerBook G4 or MacBook that had mini DVI instead, the DVIator might be worth the cost, but to pay for both that and a VGA-to-DVI converter? The V-to-D converters are *NOT* cheap...

If you were really determined, you could gut the ADC converter/controller board from the Apple display, and add your own VGA controller. Not simple, nor easily reversible. I tend to agree - get another VGA LCD for the iBook, and save the ADC monitor for an ADC Mac. Given how everything is moving to DVI and HDMI now, you should be able to pick up a decent VGA-only LCD for next to nothing.

I didn't think the DVIator would work when connected to a DVI/VGA adaptor?

No, it won't. It would have to be connected to a VGA to DVI converter, and as mentioned, they are not cheap. For starters, VGA is analogue, and DVI is digital, so the converter would have to contain an expensive analogue to digital converter or three.

think iam better of getting another VGA screen and buying one of these http://store.apple.com/se/product/M8639G/A?fnode=MTY1NDA3Ng

Yep, much better off. If you don't have a machine with ADC you can put the Studio Display on eBay for some money to put towards the new display.

yea iam gonna sell the ADC display and pickup a iBook G4 to VGA converter cable
