The ingeniously ill-fated Apple Display Connector: List of graphics cards, monitors and other peripherals

Is it, that VGA-out plainly doesn't work with the ADC-DVI-Connector at all or that I just didn't have the right adapter

All adapters in your picture are passive adapters and will not work for VGA-to-DVI conversion. They only work for DVI-to-VGA - and that's only because the DVI-A ("Analog") and DVI-I ("Integrated"?) connectors also carry the VGA signal. DVI-A only carries VGA; DVI-I carries both DVI and VGA. These adapters simply connect the existing analog pins from the DVI-A/-I connector to a female VGA connector. They don't convert the signal.

Those four pins at the right of the DVI-A and DVI-I connectors (which look like a square) carry the VGA signal. DVI-D ("Digital") does not have these pins. The Apple DVI-to-ADC adapter’s DVI-D connector doesn’t have the analog pins either.

=> You need a device that actively converts the signal. The Matrox DualHead2Go worked for me. Give that a try.

Funny thing is, that the display shows up in the control-stripe of os9 on an early TiBook (first 'Mercury'-TiBook with only VGA-out), but the display stays dark.

The adapters, while not passing through the actual video signal in your case, still pass through the Display Data Channel (DDC) pins - which allows the computer to identify the display even though it can't actually show anything. Sounds strange, but that's how it works

Many thanx! Great advise and overview!!!
Now I understand: VGA-out sends only an analog signal - the ADC-DVI-converter needs a digital video-signal for input.
Did Apple sell any acrylic flat-panel StudioDisplay with VGA-cable at all to match the Cube-G4's primary Acrylic flat-panel StudioDisplay with ADC-cable? Or is the Cube's VGA out only kind of emergency exit?

Nope.
If your Cube has the Rage 128 Pro, it can’t run two independent monitors.

• Added two DVI<-->ADC adapters by New Motion.
• Added a column for the actual LCD panels used in ADC LCDs including links to their datasheets (if known/available).

Any one know whether the LCD panel LG.Philips LM220W1-A2MN for Apple Cinema ADC 22" has a replacement model?

Panelook only lists the LM220W1-B2MN as possible replacement. The 25:16 aspect ratio was pretty much a one-off.

Updates to the WikiPost on February 2nd, 2024:

• Added an "OS 9" column for GPUs, indicating full driver support including 3D acceleration etc.
• The ATI Rage 128 Pro ADC might work in Mac OS 8.6 like the earlier DVI version does. In the Sawtooth, ADC only works as a DVI port using an adapter. No power, no USB.
• Added more info on ATI Rage 128 Pro and NVIDIA GeForce2 MX.
• Added info on whether both outputs can be active at the same time and show two different images (dual-head).
