Sadly no. The Cinema Displays do not support VGA input, only DVI. Getting a converter that takes a VGA signal and turns it into a DVI-D signal would be expensive and you could probably buy a new monitor for the price. If your laptop had HDMI output then you could easily go from HDMI > DVI > ADC since all three use the same signalling. The physical connections are the only difference.

The USB connection on the ADC adapter serves two purposes:
1. Controlling the monitor from the desktop. There are no physical buttons on the display for adjusting the brightness or turning it on/off. Those buttons are just controls that go back to the computer, which then sends commands back to the display to act accordingly. I learned that on my PowerMac G4, the power button on the monitor replicates the power button on the tower. If the system is completely shut down then I can press the power button on the monitor to start it up.
2. Provides USB pass-through for the hub built into the back of the monitor. The acrylic Cinema Displays have USB 1.1 hubs and the aluminum models have USB 2.0.

Great hack.
I’d like to connect an Apple 23″ Cinema display to my laptop but I only have a VGA output. Is this also possible and has anyone had any success at this one?
BTW what is the purpose of the USB connections on the ADC connector?
Cheers…

That is probably a good guess. The only “gotcha” would be if the PSU is switched so it would provide power unless the monitor was attached. Unfortunately, I do not have an official adapter to test with. If you plug the monitor up, and the power button doesn’t light up when you press it, I would assume the adapter is bad. A $120 adapter is cheaper to test then a new 23″ monitor.

What a great site with just the info I need, as my 23″ went dark.

I assume it’s the power supply (this would be Apple’s A1006), but just to be sure, I measured pins 1 and 11 and got zero volts where, according to the digram I should have gotten 24v.

Before I go and order a replacement unit that can’t be returned am I correct that if there’s nothing between these two pins the PSU is dead?

Hi Rich,

Please refer to post #50. I found a pristine (probably 2008) 23″ Cinema Display in the trash. But, the entire cable has been cut off about 4″ from the back of the monitor. I need information about connecting wires contained in the monitor cable to the powe supply, DVI, and, if necessary, the USB interfaces. I have accessed an inexpensive, appropriate 24 V PS and DVI cable on eBay (about 20 bucks total).

Can you assist with this project? Tony recommened I contact you.

Thanks,
George

Sounds like you will need to find out what each color coded wire is. If Apple followed the DVI standard then it should be easy to figure out. You will have to identify the USB and power lines and break them out to appropriate connectors. I would suggest looking at comment #3 in the above comments. The referenced modder may be able to answer more detailed questions since they hacked the monitor’s cable.

I found a very nice Apple 23″ Cinema Display Monitor in the trash this past weekend. Problem is, the entire cable was cut 4″ from the back of the monitor. I can access an appropriate, inexpensive power supply and DVI-D cable on eBay, but I need assistance connecting the wires.

Where can I get help with this? I’m sure it will be a project, but worth my effort if I can get assistance.
