DVI to ADC adapter doesn't work

Greetings folks,
I have an Apple DVI to ADC adapter going to a Formac 17" ADC display or alternatively an Apple 17" LCD ADC display. The displays do not function with either my MacBook Pro or my MacBook. I can't figure out which the Macs are having a problem with, the displays or the adapter. It all works fine with my PowerBook G4 and both of my PowerMac G4's. Also, regular DVI and VGA displays work fine with the MacBook Pro and the MacBook.
I have talked with tech support and they have not been able to find a solution. I will bring the adapter to my Apple store to see if they can determine the problem.

Okay, here's an update: the DVI to ADC adapter does work with the Apple displays that I have tried, but it won't work with the Formac. I have tried multiple time to contact them, but to no avail... they don't even respond to threats of posting my opinion of them, which is this:
DON'T BUY ANYTHING FROM FORMAC! They make quality products, but their customer service is a big time joke! They won't take care of you.

Apple DVI to ADC Adapter - DID NOT WORK !!!!

I have a PowerMac G4 Model M5183 and I wanted to connect it to a 20" Apple Cinema Display that I got.
Because the display output on the computer is different than the monitor, I bought the Apple DVI to ADC Adapter that everyone talks about on the support pages.
Problem is, that the start button on the monitor, will not start the computer. And if I start the computer with the ON/OFF button on it, the monitor comes on after a few seconds, the "Apple" appears and the wheel starts spinning....but the monitor goes black after about 25 seconds. I hooked comp. to a Viewsonic via the DVI port and the computer works fine. I hooked the monitor to a G4 with the ADC port and the monitor works fine. AND, I took the first Apple DVI to ADC Adapter back to the store, thinking it was bad...second one didn't change anything.
HELP!!!!!

Computer will not start with button on display.
When you use the power button on the display, the start signal is transmitted via the USB bus to the computer. The DVI interface on the computer does not have the required USB signals to start the computer. If that is a requirement, you need a graphics card with ADC connector, which requires a computer with the 25 Volt power supply.
... the monitor goes black after about 25 seconds.
That is about the time the System uses the stored Display Preference to re-initialize the display. It may mean the stored Display Resolution Preference has the wrong values for this display to sync up. You can start up from another source and attempt to delete the preference file, or start up using another monitor and set the screen resolution to something really simple, like 640 by 480.
Your Mac cannot query the display about its capabilities, because its usual method, across the built-in USB connection, is not available. So it must use the stored value instead.

DVI to Video adapter doesn´t work! HELP!

I bought a dvi to video adapter (RCA or SVideo) and I already tried on two diferent TVs and none of them worked? What should I do? Does it have a setup to do?

We really need some more details to be able to help with your situation.
Is the adapter an Apple one, or some other brand?
What model TVs do you have? Please be as specific with the model numbers as possible.
When you say it doesn't work, what exactly happens?
And finally: what kind of Mac do you have? You posted in the Mac Mini forum, but your signature says MacBook.
If it is a Mac Mini, did you set it up initially using a regular monitor first?

Cinema Display (clear) with DVI/ADC box doesn't work with MacBook Pro

Cinema Display (clear) with DVI/ADC box doesn't work with MacBook Pro when plugged in with a dvi to mini dvi cable. Any ideas what to do to make it work? I lugged the 23" 2500 miles into the wilderness and I need help

DVI to ADC Adapter + Mini DVI to DVI Adapter = usb ports don't work?

I have a 23" Cinema with the ADC plug. I've been using it with the DVI to ADC adapter for many years, though I did not use any of the monitor's usb ports during this time. I recently bought a new Macbook, so now I have am combining a Mini DVI to DVI adapter with the DVI to ADC adapter. The display works fine, but now I find the usb ports on the monitor do not work. I've checked all the pins involved and they are all straight and look normal.
Does this have anything to do with the double adapter situation, or could it just be that the monitor's usb ports are aging and haven't been used in a long time? Or is it possible these ports do not support usb 2.0 devices?

Thank you Malcolm.
It's true I cannot adjust the display's brightness using the buttons on the monitor. But I can put the Macbook to sleep, both when the adapter's usb cable is plugged in and when it's not.
So if the usb circuitry has gone bad, will this cause me any other problems, or can I just ignore it? Right now I am trying to choose an external hard drive to buy, so I'm taking stock of my available ports. I don't think I'd put a big hard drive on a usb 1.1 port anyways.

Cinema Display to be used with DVI to ADC Adapter

Hello everyone,
I have a 22-inch Apple Cinema Display (clear enclosure) connected to my Mac mini (Mid 2011) through Apple DVI to ADC Adapter.
So far, this configuration has allowed me to get beautiful OS X desktop displayed on my old Cinema Display, though it wasn't perfect.
Pressing the display's power button does not turn off the display nor put my Mac to sleep. Instead, holding the button just makes the power LED brighter than usual.
Two USB ports on the back of the display doesn't seem to work. It does charge my iPod, but any device connected to those ports (including iPod) won't be recognized on my Mac.
Can anybody see what's going on here and help me troubleshoot the issue?
Thanks.

Pressing the display's power button does not turn off the display nor put my Mac to sleep. Instead, holding the button just makes the power LED brighter than usual.
That's normal with the DVI to ADC adapter. ADC (Apple Display Connector) has pins for power control but there are no such pins in DVI so the display's power button has no way to control the computer. I don't know why the power light brightens when pushed, but mine does it too.
Two USB ports on the back of the display doesn't seem to work. It does charge my iPod, but any device connected to those ports (including iPod) won't be recognized on my Mac.
Is the adapter's USB cable plugged into the computer? The displays ports are USB 1.1. Some devices, such as iPhones, require USB 2.0.
Failure of the USB circuitry is common with those displays. My 22" ADC display started having USB problems years ago. It started with intermittent USB port problems, then it started interfering with computer sleep. Since I now use the display with a DVI to ADC adapter I don't connect the adapter's USB cable (and don't use the display's USB ports), so don't have any computer sleep problems.

Mac Mini - DVI to ADC Adapter - Cinema HD 23" ADC anybody?

I would like to buy a Mac Mini, but I'm not sure if it will handle an old Cinema HD 23" ADC through a DVI to ADC adapter. Anybody has this configuration? Which is the maximum resolution possible?

Hi
unfortunately I think the Apple store have sold you the wrong item.
I'm almost certain the DVI to ADC adapter only works with ADC based flat panel displays. DVI ports can output digital or analogue signals (or a combination of the two). The adapter seems to provide digital, which is why it works with the LCD displays, but not analogue, which is why it doesn't work with the CRT displays.
Confusingly Apple did a 17" Studio display both as a CRT and LCD.
Dr. Bott do a similar adapter but they explicitly state it's not compatible with the 17" CRT.
Unfortunately I'm not sure there's a solution, as the display has an ADC connector yet I'm not aware of any adapters available that will work.

DVI to ADC adapter STudio display will not power on when used with Mac mini

I have a Mac mini and I just purchased a used apple 17" CRT studio display. I bought the DVI to ADC Adapter as recommended by my Apple store. When I hook everything up (I have checked and redone this two times) The power light will come on for about a second when presses. When the mini powers up there is a blank dark screen. I would appreciate any ideas on this. thanks!

DVI-to-ADC adapter dying?

Hi,
I have an old 22" (not 23") Cinema Display purchased late 2001 or early 2002. It's been working fine all this time. I got a MacBook Pro 15" in April 2008. I also bought Apple's DVI-to-ADC adapter a little later. It worked great for a while. Then the USB seemed to be having problems, so I just didn't use that part of the adapter. Otherwise, no complaints. Video has always been flawless.
Lately, the video has been going out and is behaving badly enough that I either need to replace the adapter or buy a new monitor. These two symptoms arrived at about the same time:
1. With no computer connected to the DVI cable of the adapter, but the adapter plugged into the wall power and also connected to the ADC port of the monitor, I'd find the monitor screen blank but the power-button LED glowing. When it was in this condition, I couldn't then connected it to the laptop and have it work. Monitor stayed dark.
2. To fix #1, I started to leave the adapter unplugged from the wall power and only plug it in when I connected it to my MacBook Pro. This seemed to fix the problem for a few weeks, but lately when using it with the computer, the Cinema Display's screen would suddenly go black. The laptop screen was unchanged, so the laptop thought the primary screen was still the Cineme Dissplay (I had my menu bar on the Cinema Display). Unplugging from the wall and replugging the adapter seems to help, but the duration of working video is becoming less and less.
The adapter doesn't seem especially hot, so I don't think it's overheating, at least not in a major way. If the problem is the monitor, I don't want to buy another adapter to have the same problem and have spent another $100.
I scanned through earlier messages on this forum and didn't see anything that quite matched my situation.
Any suggestions?
Regards, Eric

Not sure if you've solved this yet or not, but if you haven't, try shining a torch at the monitor after it's gone dark. See if you can still see a very dim image (it may help to put an animation/movie with lots of contrast on that screen). If you can, then the monitor's backlight circuitry has given up the ghost. If you can't see an image, then it'll be something else which needs further testing... Hope that helps a little

DVI to ADC Adapter question

I've got a Quicksilver 933 (2002) and want to get the ATI Radeon 9600 Pro PC & Mac Video Card. I have a 17" Apple Cinema Display and want to add the new 20" Apple Display for an extended desktop. The ATI card has 2 DVI outs. I will need a DVI to ADC adapter. My question is, the adapters (see below) say they are good for connecting to DVI-D out and the 9600 card is DVI-I. Does this make a difference? Does anyone out there have experience running a set-up like this? I would hate to spend $200. on this card and $80. on the adapter only to find out I couldn't use the 17" Display.
My other choice is the 64MB ATI 9000 Pro Mac edition. (This has both a DVI out and an ADC out so I would save ~$200.) I will not be doing any gameing, just extended desktop work with Photoshop, Flash and Dreamweaver. Would there be any noticeable difference between the 9000 and 9600 in these activities? As always, thanks for your input.

Hi Justin,
Can I further the questioning instead of starting my
own new thread?
No, worries, Mate!
I am in a similar situation.
I have a 2003 Quicksilver 933 with dual display
currently running.
(Using a 17" Apple Display & a 17" Sony CRT).
I eventually wish to either upgrade to a 20+ cinema
display and use the 17" Apple display as my extended
desktop, but that may still be down the road a bit.
Until then, Im looking to ditch the CRT for a 15 (or
so) LCD to dave on desktop space and make an attempt
to match the 17'' Apple Display.
Ok, on to the question.
I purchased a ATI Raedon 9800Pro Mac Edition and then
noticed it only have two DVI connections. This won't
be a problem for the eventual LCD upgrade (which has
DVI connection), but I need to purchase a DVI to ADC
convertor for the 17" Apple display.
The Radeon 9800 has DVI and VGA and S-Video output, I believe. If you want to run 2 LCD monitors, one of them will have to have a VGA input (which you can't get on Apple monitors).
1) Can I expect any loss in quality/performace due to
the conversion between DVI and ADC?
No, if the adaptor funcftions properly, there is no loss from DVI to ADC.
2) I believe there are mulitple brands out there
doing this conversion. (Apple, Geffen, etc..) Any
brand looking to be more preferred over the other?
The Geffen adaptor is presently the only one which will support the 17" ADC CRT studio monitor (as well as the ADC LCD monitors).
3) With the convertor will I still be able to power
my mac on and off with the use of the display power
button?
You can power the Mac on, however, some adaptors don't allow you to power it off.
Thanks for any help.
Justin
Cheers!

Apple DVI to ADC Adapter with new mini

Has anyone have any experience using the Apple $99 DVI to ADC Adapter
with a New ( or old ) Mac Mini... I have a 22 inch Apple Cinema and
I love it... especially the non-glare screen.
The only complaints I've heard were the ADC Adapter size was large and it gets hot.
Anything else???? Does the sleep feature work?
Thanks in advance, Tom

Tom,
I currently use Apple's $99.00 DVI to ADC adapter with pre 2009 Mac Mini and Apple 17" ADC Studio monitor.
This setup in use for approx. 2 years now and to date no problems observed.
The unit's dimensions are approx. 4" x 4" x 1.5".
In use from 9:00 am this morning, in use as I type, I place my hand on unit now. The unit is warm to the touch. I can leave my hand on unit for 15-20-30 minutes. Certainly not HOT.
I have had sleep/wake problems with both mini and monitor in the past. I cant say that these issues are related to or caused by the dvi/adc adapter. I have no current sleep/wake problems.
UPS/System preference settings can also affect sleep/wake options.
Sleep feature works as the unit is also connected via usb to the machine.

DVI to ADC adapter power issue?

Please forgive me if the answer to this is already posted, I searched with no success:
Just inherited the display for a G4 gigabit ethernet model that has an ADC plug (just to confirm: http://www.dvigear.com/education/connectors//adc-m.jpg).
I would like to connect to my unibody MBPro, and I'm assuming I'd be using a Mini Display > DVI adapter, then a DVI > ADC adapter (found a few but not positive they're exactly what I need).
MY QUESTION: since the ADC display was buss powered through the G4, will it still work with my MBPro using the proper adapters?
Thanks in advance!

You need a MiniDisplayPort to DVI adapter

followed by a DVI to ADC adapter

MY QUESTION: since the ADC display was buss powered through the G4, will it still work with my MBPro using the proper adapters?
The DVI to ADC adapter contains a power supply for the display. (That's why it costs so much.) Although this setup should work, there might be problems, since the two adapters might not be completely compatible. See if they will let you bring your display and MBP to the store to try them.

DVI to ADC adapter

This one is a little tricky...i have a 20" Apple Display with an ADC connection.....my friend who owns an older G4 believeed to have a DVI-D and VGA connection wants to buy it but we're wondering if there is any way to hook it up.....I have an Apple DVI to ADC adapter but I don't know if it works for just DVI-I or what...he lives a few hours away so we can't just try it out....if anybody knows anything please let me know.
thanks.

DVI to ADC Adapter issues

I have a PowerBook G4 and a 17" studio display that is connected to a DVI to ADC adapter. One day I must of done something because now when I start up with the monitor connected is immediately shuts down the system. Also when I have my lap top turned on and I plug in the monitor It goes through the start up process and the 17" will display the shut down selection and then just quit! Very frustrating!!!
I did check to make sure that the monitor is working and it is. I checked it on my G$ box and it started up perfectly! Any idea as to what is wrong or what I need to change on my PowerBook to make the monitor work? Any ideas will be greatly appreciated!!!

So can you confirm that this is the adapter you are using, and that the power supply (top item in the picture) is plugged into a live outlet and appears to be providing power to the display?
