Displayport to ADC?

Can I use the displayport to dvi and then plug that in to my old DVI to ADC adaptor and plug in my old (but still working!) 17 inch display?

Has anybody actually got this to work? I've just tried it -- have an ADC monitor w/ DVI adapter -- that worked fine with my (first generation) MacBook Pro's DVI input. I tried adding the ($29) DisplayPort adapter, but my (new) MacBook doesn't see the monitor. No amount of restarting/"Detect Displays" shows any recognition of the external screen. Any ideas?

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:

Of course you'll also need a Mini-DisplayPort->DVI adapter:

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

How to connect 22" Apple Cinema Display with ADC to Mini DisplayPort?

What are my chances to connect a 22" Apple Cinema Display with ADC connection to my new MacBook Pro with its Mini DisplayPort? Is there a combo possible of some adapter with some cable for instance?

Does DVI-to-HDMI work with my Mini DisplayPort to DVI adapter?

Hi,
I have a Mini DisplayPort to DVI adapter and was wondering if I get a DVI-to-HDMI, will I be able to get HDMI output?
If yes, should I get any specific DVI-to-HDMI adapter?
If yes, will it have sound with it?
Thanks.

So which does the community prefer between Dr Bott DVIator and the Apple DVI to ADC? I have the Apple but it is not working, as it is shutting the monitor down without even starting it (soft shut-down). Is this a bad adapter or the result of "stacking" adapters? I have read that it is more common to a bad adapter result.
Thanks.

Mini DisplayPort adapter for 23" Apple HD Cinema Display?

hello all,
I'm sure this has been asked and answered here, but I can't find it! (grrr...)
I've got an 23" Apple HD Cinema display and a new iMac. The iMac has a "mini DisplayPort". Now, the Cinema Display has a 3 x 10-pin (not 3 x 8) DVI connector. The WIKI thing about DVI calls it a "DVI M1-DA (Dual link + USB)".
http://en.wikipedia.org/wiki/DigitalVisualInterface
For the life of me, I can't find an Apple (or other) adapter with the 10-pin connector to attach to the iMac?
many thanks,
b myers

If it's the old, plastic cased, 23" display, it may use ADC (Apple Display Connector).
<http://upload.wikimedia.org/wikipedia/commons/0/09/AppleDisplayConnector.jpg>
In that case, you will need a DVI to ADC adapter

Is it possible to connect an old cinema display (ADC) to an Imac (2012)?

Hello,
I want to add a second screen to my Imac and I found a Cinema Display (ADC). I went to see the screen and i connect it to my Macbook to test if it works. The guy who sold the screen had an ADC to DVI adapter and I bought an DVI to thunderbolt connector. It didn't work. He also tried to connect it to his Imac and still the screen didn't work. Is it even possible to connect the screen to an Imac?

Is it the Apple version of the DVI to ADC adapter? The signals from a Mini DisplayPort (or Thunderbolt) to DVI adapter may be weaker than normal DVI signals. The Apple DVI to ADC adapter amplifies the DVI signals, so can work with signals that are too weak for non-Apple adapters.
An ACTIVE Mini DisplayPort to DVI adapter may produce stronger DVI signals.

IMac 27" (Late 2009): getting audio to HDMI receiver via mini DisplayPort

I just got my first iMac 27" and I'm in the process of integrating it into my home theater system. Here is my setup:
iMac 27" connected to HDMI receiver (Yamaha RX-V1800) via mini DosplayPort, using miniDP-to-HDMI adapter + HDMI cable
Optoma HD20 video projector connected to HDMI receiver (HDMI out) via HDMI cable
I have Windows 7 installed via Bootcamp 3.2, so that I can take advantage of Windows Media Center. With the above setup, I am not getting audio or video signal to my receiver and video projector when I'm using Windows 7. However, when I am in OS X environment, I can get both video and audio signal to my receiver and video projector, and either mirror or extend my video diplay. When I do plug in my iMac straight into my video projector or LCD monitor with built-in speakers while in Windows 7, I get both audio and video output. So why doesn't it work -- and only under Windows 7 -- when the signal goes through the receiver?
My immediate thought was that it must be something about the receiver, but since the setup creates no problem under OS X I don't think it is. Could it perhaps be the Windows driver for mini DisplayPort, because it looks like iMac is not 'recognizing' my receiver and therefore not establishing connection? Is there a driver of fix available that takes care of this problem?
Thanks!

I've tried a few times and it hasn't worked so far...

MacBook Pro & Mini DisplayPort

I have been looking into options to upgrade my systems for photo editing. I'm now thinking about buying a 24 inch Apple LED Cinema Display to hook up to my MacBook Pro. My video output port is DVI (not mini-DVI). Is there an adapter I can use from my DVI to the Mini DisplayPort on the display? It is not clear from what I see in the Apple website. Also, can I plug in, and use, an external keyboard when the display is connected to the MacBook?

The discussion was started in October '08 (about 9 months) as that's when the MiniDisplay port was introduced on the Apple portable lineup. Currently, all "shipping" models from Apple come with MiniDisplay Port was the standard video out connection, the only machine capable of DVI is the Mac Pro with appropriate video card selection.
I'm sure when an adapter is made which supports "reversing" MiniDisplay Port to DVI then there will be enough topics on it. My understanding of how the technology works is that it's not possible, but the fact that there is development on it would indicate otherwise.
It reminds me of when Apple use to use their proprietary ADC hook up for their displays. I guess I had thought that with standardization of VGA & DVI we'd ok with using that for years to come. I guessed wrong on that, too.

Matrox DualHead2Go and ADC Display?

I have an older 17" acrylic display with that big ADC-DVI adapter. I'm currently using my Macbook Pro (ATI X1600 video card, Dual-Link DVI connector) with a surprisingly good HP VGA panel, the same resolution as the Cinema Display.
Has anyone had any luck with using an ADC monitor with the Matrox DualHead2Go? I'd like to connect both of these displays to my MBP, and have heard concerns about compatibility with certain devices and the ADC adapter. Secondly, does anyone know if the DualHead2Go can support mismatched signals, at the same resolution(1x DVI, 1x VGA).
I suspect I need the Digital Version, but it seems that because the signal has to turn into VGA first, it may not work with the ADC display. So third, is the Macbook Pro capable of connecting to the newer DisplayPort version of the DualHead2Go? Assuming someone makes a DVI-Displayport connector.

The idea behind the DualHead2Go is that the two displays be matching displays, so mismatched resolution won't work AFAIK. But you can ask Matrox that question to be sure.
If your MBP has DVI for its output, then it won't be compatible with the DisplayPort version of the the DualHead2Go.

Early (Jan.04) Cinema 20" display with ADC:

Need to replace video card in G5 (Jan 04). Need video card with ADC. Any suggestions as to where to purchase this. Tried DV Warehouse already. To expensive for refurbished card. Can I get around the ADC on new video card.

The Mac Pro features one DVI-I, to which you can attach your DVI-display-with-powerbrick-in-cable, and two Mini DisplayPort.
ATI has moved forward smartly into Mini DisplayPort, nearly shortchanging users of what they call "legacy" Interfaces such as DVI, HDMI, and VGA. In order to run Three legacy Interfaces, ACTIVE (read Powered) adapters are REQUIRED.
What appears to be happening is that "the simulation of DVI" provided is a little short on power. If you don't run the ACTIVE adapters that include an additional USB for still more power, you can't run three.
Some users have reported that passive adapters used for ANY DVI displays are having sporadic trouble. The low-cost ACTIVE Adapters contain signal Drivers that use an internal power lead. The pricey Dual-Link adapters need two sets of Driver circuits, and go to an external USB cord to pick up still more power to run them.
Executive summary: There may be sporadic problems with signal levels for certain displays. If an adapter is needed, an ACTIVE DVI adapter is recommended.
If running three DVI displays, ACTIVE Adapters that also include an extra USB cord are REQUIRED.

Two ADC 17" mac displays w/Mac Pro?

I have a pair of the older 17" Mac displays with ADC connectors. I used them with my old MDD G4, which came with a video card that had DVI and ADC connectors. So, I obviously had to buy an ADC/DVI converter so I could use the DVI port that the computer came with (one of the monitors just plugged into the ADC.)
Now that I have the new Mac Pro, with two DVI connectors on the card, does anyone think there would be a problem buying another ADC/DVI converter so I can use two monitors with the Mac Pro? I just wanted to make sure.

"• the 27" is directly connected to the other MDP port.
• One of the 20" monitors is using the MDP adapter into the 5770.
• When I try to hook up the other 20" to the DVI port on the 5770 I get nothing.
Note: If you are using an Apple Mini DisplayPort to DVI adapter, only two displays are supported across the three ports.
If you are connecting three displays, any DVI displays must be connected to either the Dual-Link DVI port or must use an Apple Mini DisplayPort to Dual-Link Adapter.
You MUST use All "Active" or "Powered" Mini DisplayPort connector such as the Apple Dual Link, or you can only use two displays

17" Studio ADC display to Thunderbolt

I have an old PowerMac G4 that I use with the ADC display. Well I will soon be aquiring a new 13" MacBook air. I want to know if I can use a series of adapters to hook up my old ADC display to my new MacBook w/ Thunderbolt. What do I need?

If it is a LCD display, not CRT, you can use a Mini DisplayPort to DVI adapter

Formac Monitor ADC connectivity

We have a razor sharp Formac monitor that had been mated to an ADC connector with our old G4 tower.
Would like to move it to a new Mini and have a second Mac for our household that can run the current OS version.
Is there any reasonably way to connect these two? (Ironic that an Apple-invented bit of technology is the problem.)
This would be in addition to our late model iMac 2.4, which is the work horse of the home.
Thanks much.

You'll need to look for a DVI to ADC adapter. Such were made by Apple themselves and Gefen, and perhaps other companies, but have all been discontinued so you'll have to look to dealers or private sellers. There are some Apple units (Apple M8661LL/B DVI to ADC Display Adapter ) listed by Amazon affiliates, and you may find others on places like eBay.
If you find one, you'll then need a mini-DisplayPort to DVI adapter.
Regards.

27: iMac Apple Mini DisplayPort to DVI adapter quits working post-firmware

I iMac Apple Mini DisplayPort to DVI adapter suddenly quit working after I installed Apple's latest iMac display firmware update. This is an Intel Core i5; the monitor is an LG Flatron 24" Wide, and when it powers up it says "no video input" and goes into power-saving mode. No amount of replugging cables helps, but the monitor works fine on other computers.
The Displays control panel just shows one monitor, and clicking Detect Displays does nothing.
I suspect Apple's Display Firmware Update. My installer log shows the following, but the problem only happened today after the latest update:
6/1/10 9:45 AM 27-inch iMac EFI Firmware Update 1.0
6/1/10 9:45 AM 27-inch iMac Display Update 1.0
6/4/10 11:47 AM 27-inch iMac SMC Firmware Update 1.0
6/4/10 11:47 AM 27-inch iMac Display Update 1.0
6/5/10 7:29 AM 27-inch iMac Display Update 1.0
I have automatic updates disabled, but after each update I would see more firmware updates ready, but caution leads me to never install more than one of these at a time, and then to wait a while to see if anything bad happens. The odd thing is that the Display Update 1.0 seems to have been installed three times in this course of events. Alas, there appears to be no way to uninstall a firmware update.
Here is the System Profiler Graphics/Displays output:
Chipset Model: ATI Radeon HD 4850
Type: GPU
Bus: PCIe
PCIe Lane Width: x16
VRAM (Total): 512 MB
Vendor: ATI (0x1002)
Device ID: 0x944a
Revision ID: 0x0000
ROM Revision: 113-B9110C-425
EFI Driver Version: 01.00.383
Displays:
iMac:
Resolution: 2560 x 1440
Pixel Depth: 32-Bit Color (ARGB8888)
Main Display: Yes
Mirror: Off
Online: Yes
Built-In: Yes
Connection Type: DisplayPort
Display Connector:
Status: No Display Connected
It says the Mac sees no display connected, and the display gets no video signal. Since the adapter is an active device (it has powered electronics to convert DisplayPort signals to DVI signals) I suppose it could have just coincidentally died. But that seems unlikely given that the thing worked perfectly just before the last firmware update.
Does anybody have similar experience, or better yet, a fix?

Unfortunately the Apple Knowledge Base does not give much information about this update. Such has how to tell if it has been successfully installed. I suspect that because it keeps recurring in the install log that it has not been installed successfully as yet. Are you receiving this update through Software Update? Can you locate the installer for this update? It maybe located in Apps/Utilities.
Some firmware update installations can be interrupted/corrupted by attached devices. If you find the update's installer on your iMac, I suggest that you detach all external devices from the iMac, use an Apple USB keyboard & mouse if available, follow the instructions carefully and install the update manually. If you do not locate the installer I suggest downloading manually from the link below and installing it.
The Knowledge Base article mentions that your iMac should also have a Graphics Firmware Update. I suggest that you download and install that as well.

Apple Mini DisplayPort to VGA Adapter flickers

I have 2 Samsung SyncMaster 23 in, HD Displays connected to my Mac Mini. The Display connected via the Mini DP to VGA adapter flickers erratically. This started happening after installing the latest upgrade of OSX Mountain Lion. I called Apple support, they gave me a list of steps to try to fix the problem, which I followed to the letter, to no avail. The problem is annoying, to say the least. I tried to find out if there was a firmware update for the adapter, but I am running the latest firmware (1.03).
I would appreciate any help to solve this issue.

Thank you for your message.
1. Both monitors only have VGA input.
2. The other adapter, Mini-DVI to VGA has always worked properly.
3. The Mini DisplayPort to VGA adapter is an Apple original product I bought at an Apple store. I bought 2 adapters.
4. Actually I have 2 Mini DisplayPort to VGA adapters: The one I use with my Mac Mini, and another adapter I use to connect my Mac Book Pro to a Panasonic projector.
5. I have tried using both adapters, and the flickering problem is present using either adapter.
6. I believe the flickering problem is definitely something that needs to be addressed and solved by Apple. The adapter is its product, and should work as advertised, no matter what version of OSX I am running. Please remember that there was no flickering before I upgraded to the latest OSX Mountain Lion.
7. I do not believe buying an adapter from another manufacturer, as you suggest, would solve the problem.
Thank you for your help.
