DVI to ADC Adapter problems.... Hopefully

Hi Everyone.
I recently upgraded to a G5 with the ATI 9600 default card. I have a 19" crt (connected to via VGA/DVI cable) and my 20" Cinema display (ADC - connected via DVI to ADC convertered - brick ($100)).
Until recently everything has been great. Until my Cinema display screen has a reddish/ pinkish tint to it. I am going to guess that it it the DVI converter - have read a few posts here and found similar posts - because the screen does revert back to normal - eventually. I have cleared the pram and unplugged the brick to let it cool down etc. I think it seems to be a overheating problem. Just wondering if anyone else has similar experience with the dvi to adc converter. I would bring it back to the apple store but of course it will probably work by the time I got it there. I did take some snaps with my digital camera as proof - gee should have thought of that earlier.
thanks

Hi Paul,
A tinge on the monitor can sometimes be due to a single bad connection. This has been documented in the Flat Panel iMac discussions where a single loose wire (in the neck swivel assembly) caused much the same problem.
The issue is more likely to occur with a DVI to ADC adaptor because you have twice the number of connections, hence twice the chance of a faulty connection. The connection may be sufficient for normal function initially, but, as things heat up, the connection might go faulty (probably due to heat expansion).
If all connections are OK, heat should not be an issue with the DVI to ADC adaptor.
It might be a good idea to check all contacts and connections in the video card port to adaptor to monitor plug sequence for dirt, corrosion or damage/distortion. Once that has been done, make sure that all connections are tight and properly seated.
It would also be a good idea to have a quick look at the video card also, maybe even reseat it, to make sure that all connections are OK there too.
Cheers!

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.

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.

Nothing simpler, smaller, less expensive than Apple's DVI to ADC adapter?

My 2001 vintage 466 MHz PowerMac G4 with 15" Studio Display has served me well over the years. But, alas, she's running Panther (10.3.9) and lacks the requirements to move on to Leopard, which I'm ready to do. So, I decided to upgrade the machine. Since the other parts of the system (monitor, keyboard, mouse & printer) were just fine, I decided that a new Mac Mini would fit the bill nicely. (I'm also a Scotsman, always looking for ways to save money. Perhaps that's part of the problem. )
I received it yesterday and wasn't expecting the ADC-monitor to DVI-computer dilemma. (Which shows you just how out of touch I am with technology's incessant march forward.) So, I investigate solutions.
Imagine my surprise when I discover that the only solution out there is by Apple, in the form of a brick almost as big as my Mini! And, another $100 to boot! I did find a third party solution through a link on Apple's website, but that's $150! (Thanks for the referral, Apple!) My mind is boggled - there must be other available solutions but, if there are, they are evading me.
Does anyone know of any solution that is simpler, smaller and less expensive than Apple's DVI to ADC adapter?
Thanks for any and all info.

The Apple adapter is the only solution if you really want to keep that display. It might be a good time to look for a larger display, with DVI.
I am using the Apple adapter with my seven year old 22" display, but I wouldn't want to run OS X on anything smaller.

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.

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.
Regards,

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!

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 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 forcing powerbook to shut down on connection

Hi there,
I have been using my powerbook 1.25GHz for about 8 months with my DVI to ADC adapter to connect to my 22" cinema display with no troubles whatsoever. Yesterday evening when I came home as soon as connected the adapter to my powerbook- it shut down my powerbook within a couple of seconds. Not only that I was blasted with a 3-5 second low tone from my powerbook as it attempted to restart. At the same time the sleep light (one that purrs softly in sleep mode on the powerbook) flashed in quick succession for the length of time that my powerbook made the the long beep noise.
Following this the computer then makes the usual start up noise but nothing happens on either my powerbook display or the 22" display. I am then required to take out the adapter connection from my powerbook and my computer restarts normally after holding down the start button again.
I have tried a few times now to connect the adapter with the same problem. Has anyone else experienced this or have any idea what the sound being emitted is all about and the disco light display from my powerbook?
Would be grateful for some hints... Thanks!
1.25 GHz PowerPC G4 Powerbook Mac OS X (10.3.9)

The exact same things (low tone, furiously flashing sleep light) has happened to me on several occasions, and it happened again today. I just googled up the symptoms and this is where I landed. The only thing I can correlate among our experiences is that the DVI connection on the powerbook is involved (the problem may or may not have anything to do with the ADC adapter).
For my problem, it's usually occurred after I've either just connected or disconnected a second display using an Apple dvi-->adc powered adapter or a small unpowered dongle (dvi -->vga) for an lcd projector. The restart after either one fails can take quite awhile.
Twice in the past six months, I've been at the "two minute warning" before a presentation, and the book has crapped out just as I connect it to the projector and then it's gone into the psycho light and sound mode you described. Today's failure occurred after unhooking from the powered Apple DVI-->ADC adapter at my desk to go down the hall for a meeting. The computer went into blue screen and stayed there after it was disconnected from the Studio Display and DVI-->ADC adapter. Attempting to hard reset/powerdown by holding down the power button initiated the tone/light flashing.
These few cases may seem pretty isolated, but perhaps a pattern will emerge if people keep adding their experiences.

DVI to ADc adapter- missing ac power cord

HI, I recently obtained an dvi to adc adapter for my apple display however the adapter came without the ac cord which powers the thing. Normally this wouldn't be a big issue, but because it is an apple product the cord that powers the adapter has a unique 3 leaf clover dongle which makes
it difficult to replace. I was wondering if there is some way to either obtain another ac cord or to adjust an existing widely available ac cord to fit the adapter's form factor.

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).

DVI to ADC Adapter Overheating

My DVI to ADC Adapter overheats when I plug in a 22" Apple Cinema Display M8058. I've used this adapter with my powerbook and after about 30 minutes or so it is hot enough to cook an egg on the apple and it shuts down and the display goes dead. The same happens with my G5. Once it's cool it fires up. It works ok on a smaller ADC display without shutdown. I can't find anywhere where overheating is an issue and wonder if this adapter is a fire hazzard or I got one that's gone bad ? Anyone else have this problem?
G5 Mac OS X (10.4.5)

Yes , that's true , my Adapter is overheating too , but I have Drop-Outs at the resolution 1600x1024 ono my Cinema Display 22". I think it's a case of warranty.

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.

G5, DVI to ADC Adapter & Belkin Switch

I've got a Dual core 2ghz G5 running 10.4.11, currently connected to a 23" old style cinema display.
I have bought a DVI to ADC adapter (the one with power) and a Belkin DIV-D Switch so that I can run a PC and the G5 through the display.
The problem that I'm having is that the G5 won't start up when connected through the switch, it just turns off when OS X is booting.
If I boot the mac and the connect the the screen via the switch then I get no picture on the diplay, although the keyboard and mouse appear to work.
Everything works fine for the PC.
Any ideas?
Thanks

I just bought a KVM and this time I went with a Gefen, and while it is just for DVI, it works quickly and reliably. In the past I always bought cheaper units and was never satisfied.

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.

I just bought a recertified Mac Mini, and I wonder if anyone here knows if it's possible to hook up my Mac flat screen LCD monitor to it using what adapters? I currently have a DVI to ADC adapter connected to my G4 Powermac.

I just bought a recertified Mac Mini core duo - it's not the newer model-, and I wonder if anyone here knows if it's possible to hook up my Mac flat screen LCD monitor to it and using what adapters? I currently have a DVI to ADC adapter connected to my G4 Powermac.
The company I bought it from is not Apple, and I may regret that. It was in my price range, though.
This is the first time I've used this community, and I've been a Mac owner since 2000. Thanks in advance!

when you say "Mac flat screen LCD", do you mean this:
