ADC - DVI - ADC Connection possible?

Hi Everyone,
We put one of our editing machines around to the other room to get it out of the way. In order to make the cable long enough we had to buy an ADC-DVI converter. Run it to a 15' DVI cable, to the mac, then that DVI connection back to an ADC connection on the graphic card. The monitor won't turn on. Is there something plain wrong with connecting things this way around? Any help on the topic would be mucho appreciated since we tried to upgrade to a new card and still experiencing the same problem. Perhaps some kind of incompatibility issue with stepping back and forth between the connections?
The monitors are 1 23" Studio and one 17" Studio both LCDs. They are in proper working order, and if you connect direct into the ADC port without the adapter it works. Radeon X800 Mac edition card under the hood as well.

Yes. as far as I can tell, the only time any problems come up is when the ADC-DVI adapter gets thrown into the equation (although, it does work when I want to send a signal to a regular DVI monitor) its left me completely clueless and apple tech couldn't figure out what was going on. You pretty much described our set up perfectly. Seems to be quite the troubleshoot here.

ADC port on graphics card, to ADC to DVI adapter, to
15' DVI-D or DVI-I cable, to DVI to ADC adapter (the
one with the power supply), to ADC LCD display should
work.
Does the ADC monitor work with the DVI to ADC adapter
if you plug the adapter directly into the DVI port on
the graphics card?

ADC/dvi video card

Is it possible to get a ADC/Dvi video card for an open PCi X slot? or would I be better off getting a card w/2 dvis and purchasing the adapter because it is older technology? I have an older 23" display.

A PCI slot wouldn't have the extra connector that provides the display power, so ADC cards are only made for AGP slots.

What can I expect from DVI-ADC Adaptor?

Hi,
I'm hoping to use my old 23" Apple Cinema Display (circa 2000) with a new quad. Due to the high cost of the DVI-ADC adaptor and the fact that it uses active circuitry, I'm curious to know if I can expect any loss of quality or responsiveness.
Also, will the USB ports still work and are there any other issues I need to know about?
Many thanks,
Colin

The Apple dvi to ADC connector is powered. I have mine plugged into a Kensington MasterPiece along with my G5 and whatever else.
The ADC cable connector from the ADC Display connects to the Apple power module. Also on that cable is a usb connector that goes to the G5. So I had to route my keyboard to the ADC monitir because I connect a USB hub to the second USB port on the G5. The keyboard works fine as does the ADC monitor. I have the 20 inch Display.
The only issue I have which is not a biggie is in sleep mode. The ADC monitor sleeps without the glowing power light on. Once I touch the keyboard which is routed through the ADC monitor the monitor and computer awakes.

ADC-DVI = green screen

Hello
I experienced the "green screen" problem connecting a second monitor to a G5. I suppose it's a problem of wiring in the ADC-DVI adapter. Does somebody know how to hack the adapter to let the monitor get the right signal from red and blue channels? ADC-VGA adapters are no longer available, and I don't want to put a second video card.
thanks to everybody

Hi-
Welcome to Discussions!
First, check that no pins within the connectors are bent.
If you want to rewire, here are some pinouts:
ADC connector pinout
DVI connector pinout
VGA connector pinouts

Mini with 22" ADC Cinema Display w/ADC-DVI

Greetings...
I've been playing with my new 1.4Ghz mini and the display I happen to have free right now is an original 22" Cinema Display. I have the ADC to DVI adapter for this display and it's rock solid on my old G4 Sawtooth. Anyway on the mini it works very nicely exept for one problem. I get a flicker that seems to tie to system activity. May be voltage variations effecting the internal video DVI drivers. OK my question it. 1) Has anyone else out there tried this combination? (Apple's monitor compatibility chart says it's supported so I know somone at Apple tried it). 2) Do you have any image stability issues like flickering. I'm asking this because I'm now wondering if maybe my little guy is a bit faulty in the video department. I'll try my new 20" display tomorrow to see if it has the same problem.
Anyway this is an amazing little box. BTW mine currently has the minimum RAM but that will change as soon as I put this video issue to bed. Hope to use it in my studio because it's so quiet... Very nice in the sound department.
Enjoy,
--Bryan

Good news...
Well I managed to locate a rev B version of the DVI-ADC adapter. First good news is the price is now down to $99 from the original $150. Second good news is that the /B version seems to work. No more flicker!!
Hey Michael L... Thanks for the suggestion it worked!!
So while this isn't the cheapest solution, it does seem to work so far and considering the cost of a new 22 or 23" monitor vs. using my excellent 22" ADC Cinema Display I'm feeling OK about it.
So John you might want to give a rev. /B version of the adapter a try. BTW the actual adapter is absolutely identical to the REV /A version on the outside the only difference it the serial number is in a different range. If you buy an open box make sure the serial number matches on the box that shows the /B revision matches the actual unit.
Happy Hunting... They are not easy to find. Yeah I know this $600 Mac is starting to rack up the bucks but hey considering it has better performance than my original G4 Sawtooth that I paid like 5X as much for I can't complain too loud...
This will hold until Apple can produce a new truly drool worthy high end machine. The bar just went up with the introduction of the mini. The new once has got to be small, it's got to be silent and it goes with out saying it's got to be so fast it will make you cry. Until then I'll use what I have right now...
Next I need to track down a good 1GB stick of ram for the Mini...
Enjoy,

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

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 & ADC video card upgrade???

What can I get to replace the stock 64mb AGP card (at least I think it is) in my MDD Dual 1.42 machine. I currently run two Acrylic Cinema Displays, a 20" via DVI and a 17" via ADC...
Is ADC going to limit my options? If so, I can use a second ADC-DVI for the 17" monitor.
Any help would be great.
Thanx

Okay, so it sounds like I should "dump" the ADC idea.
Then an I looking for a card with 2-DVI or 1-DVI and 1-VGA ???
I've followed several of your discussions, but still need a little help with the Video Card upgrade education. Flashed cards kind of scare me, but are they okay to use? I don't know if I could tell the difference anyway. Asking a seller on eBay if it is in most cases won't get you anywhere either.
You've talked about the 7800gs card. Any others I could consider? I've read that some cards don't work in a FW800 MDD machine.

Yellow screen on external TV Monitor via DVI-ADC Adaptor

Hello,
I am using a 2008 17" MacBook Pro with a DVI-ADC Adaptor in order too use an external monitor, however whenever I set it up the 2nd external monitor has a yellow tint all over the screen.
Does anyone have any solutions to resolve this?

I don't think so... you need to look at either an iO HD or a Matrox MXO to take care of things I'd think. Might also be able to use an Intensity Pro Card (least expensive solution).

ADC DVI HDMI for external viewing of HD footage

Hi,
I have an HDTV that I want to use as a second monitor but primarily as an HD monitor for external playback from Final Cut. I need to know if this will work before I go and buy all of these cables.
Can I go out of my ADC with a ADC > DVI then go into the TV with DVI to HDMI? Would that work. Can I bypass the DVI and just find an ADC > HDMI cable? I don't even know if there is such a thing.
Thanks for the help.

I just posted this on another msg board regarding the topic::
Here is the link to the post too:
http://www.avsforum.com/avs-vb/showthread.php?p=7922323#post7922323
I just received my cables in the mail today and set everything up.
This is what I did:
Dual Mac G5 2.5 w/ ATI x800XT
DVI -> Apple Cinema Display
ADC -> Belkin ADC to DVI Monitor Adapter -> Gefen DVI to HDMI Cable
Going to a Samsung 32" LN-S3251D
I did run into some little issues that I am trying to resolve. For some reason this setup did not initially work because my television would not switch to HDMI input. I don't think it was receiving a signal although in my system preferences it detected both displays. So I put the cinema display on the adc to dvi adapater and the LCD TV directly to the DVI output on the ATI card. This worked but tweaking resolutions and messing with the mirror mode wasn't producing what I wanted.
So while the computer and all the displays were still on, I switched the cables back to the original set up. Works perfect. I have 1 inch of black space running vertically to the left and right of my desktop (on the LCD TV). My cinema display looks the same as before. This is on mirror mode.
The thing I can not figure out, is how the **** can I keep this setup without losing the signal to the tv. If i switch to a different input source on the LCD, I can not get back to the HDMI with the computer showing
I am kinda new to this stuff... Any suggestions?
Cheers,

Mini-DisplayPort- DVI- ADC

A couple of my users still have old ADC Cinema Display monitors that are otherwise working correctly through DVI->ADC boxes. Has anyone had any luck chaining the MDP->DVI to the DVI->ADC connector to get this setup to work properly?

As far as I know, Apple's DVI->ADC adapter is the only one available. Here it is:
http://store.apple.com/us/product/M8661LL/B?mco=MTIxOTI1OA
Of course you'll also need a Mini-DisplayPort->DVI adapter:

You can buy one from Apple, but it will cost twice as much.

X800xt vga or 9800xt pro adc+dvi ?

Hi
Yesterday, I received a second hand X800XT that I plugged in my PowerMac (2x2GHz). First deception, it had a DVI and a VGA port, not a DVI+ADC as the 9600 I used to have until then.
I worked a moment but never could get a DVI signal. I however got an expected 1600x1200 through the VGA port. Seemed responsive using Aperture but it'd have to be recalibrated.
The seller confirmed me that this very card can only feed 2 VGA monitors, no DVI.
He proposed me to swap my X800XT for a 9800XT with the expected port and 256MB of VRAM.
So, my question is:
As I work primarily with Final Cut Studio and Aperture, what's better for me:
1) To keep the X800XT and feed 2 VGA (LCD) monitors with it?
2) To go for the 9800XT
3) to just forget about that and keep my 9600 1st gen with 64MB which at least could decently feed both of my ADC and DVI monitors but not quick enough to work in real time with Motion or Aperture?
I really need help here, thanks in advance.

Hi
I've seen some X800XTs on eBay which are PC cards flashed with the Mac ROM. These happened to explicitly state the DVI port was only functional as a second analogue VGA port using an adpater (supplied). It sounds as if the card you received is also a flashed PC version.
The 'official' Mac version has a DVI and ADC port (both fully functional). It's fairly expensive in comparison though and Mac compatible ATI cards in general seem to be in short supply at the moment.
If you've already got two digital DVI or ADC monitors, I'd personally be reluctant to switch to analogue VGA which would be a backwards step. I guess a fourth option, return the card and buy the official Mac version when available would be the best solution, budget permitting.

DVI-ADC Connector Conversion?

Hello my freinds
I'm sure this question has been asked before: Looking for a connector/adapter that will allow DVI out, (from a video card), to an older ADC Style Monitor. Not sure such an animal exists? I'm very familiar with the limited variety of PCIe video cards for the older Dual Core machines. Most used/flashed cards on Ebay are either Dual DVI, or older/slower combo DVI-ADC (128 MB or less).
My 1st choice would be a 256MB PCIe card with combo DVI-ADC - they are difficult to find. Hence my question regarding the conversion.
Thanks again

Hi Mike,
Yes there are 2 or 3 types, but they're expensive, might even be cheaper to buy a new DVI monitor.
Apple made one, Dr Botts, & maybe Belkin?

Edit: Oh & don't confuse the ADC to DVI adapters with the DVI to ADC adapters, the later having the needed Power Supply for the ADC Monitor.

ADC-DVI issues ?

I am using Boot Camp on a 2.66 Mac Pro. I have a ADC-DVI adapter on a second monitor, to which I have plugged in my USB mouse. I note that after the last set of updates, when I boot into Win XP, the mouse is off. If I quickly (within 20 seconds or so) go, and unplug and replug in the USB cable from the ADC-DVI adapter, the mouse comes back on. If I wait too long, this doesnt work, and I have no mouse no matter where I plug it into .
Anyone else see this ?
Mad Dog

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?
Apple DVI to ADC Display Adapter

Would like to use both ports adc dvi for hdmi for maca1047

I have a Mac A1047 dual 2.0 and would like to use both ports, adc/dvi to hdmi is the an adapter for both? I am in Michigan is there a store here does apple store carry anything like this and do I have to go online?

Hello, it may be tough finding an ADC->DVI adapter, & not certain ADC->DVI->HDMI 2 adapters will work.
I'm reasonably certain Apple no longer carries anything for ADC.

DVI / ADC Converter Display Issue

Hey all, any help would outstanding. Picked up a Radeon 9200 (PCI) for my G4 Dual 533. Running it to a an older 17" Studio Display. Had to score the DVI/ADC Converter. But here's the problem, when I plug it all in, I get no image on my monitor. Have tried taking my old GeForce 2 out when I try it, leaving it in, etc.
The S-Video out works fine and I can send to a TV no problem. Have all most recent updates for the Radeon card and OS X.
Any ideas? Appreciate it!

In the link I gave, one person was using the Gefen adapter, but the power supply was getting VERY hot. Buying the Gefen adapter and a new, bigger, power supply, would be the easiest way to get things to work. The only cable cutting would be moving the cable from the Gefen power supply to the new power supply. That would just be a two wire cable. If you can find the matching plug for the Gefen power supply, you wouldn't have to use the Gefen power cable, but make your own, which is probably better because Gefen might be using wires too small for the extra current.
