Mini-DVI to DVI to ADC problem

I have recently acquired a 20" Apple Cinema Display with an ADC connector. I wish to hook it up to my 12" PB G4 with a Mini-DVI port. I have read, however, that Apple's included Mini-DVI to DVI adapter is DVI-D, and that Apple's DVI to ADC adapter is DVI-I. Does this mean that I need to plug a DVI-D to DVI-I adapter into my Mini-DVI to DVI adapter, and plug my (as yet unpurchased) DVI to ADC adapter into that?
On the Apple store it is stated that the DVI to ADC adapter is useful for connecting a grand old ADC Cinema Display to a Powerbook G4. Is this correct? Or does this only apply to the 15" and 17" models with full DVI ports? Must a Powerbook 12" user buy another (third party) adapter to get this hulking great monitor to work? Will it even work with three adapters between the machine and the screen?

I don't have much to suggest, except to ask if you can try with a different mini-DVI to VGA adapter. (i.e. do you have more than one on hand to make sure yours isn't just defective?) Make sure it is firmly seated into the iMac.
I use the same adapter to provide an extended desktop on an old CRT monitor and the display is great.

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.

Mini DVI to DVI doesn't fit DVI to ADC connector supplied with my machine

The DVI end of the ADC adapter has small pins above and below the blade side of the plug while the DVI end of the mini-DVI to DVI adapter has no openings to accept them. Both of these items were shipped to me by Apple with my 12" PB. Any suggestions?
I suspect someone must have encountered this but I didn't see it anywhere when I did a search.

My apologies. I confused an adapter from another company with an Apple product.

Mini DVI to external monitor (VGA) problem/firmware update does nothing

Hi,
Four months ago I bought a new white 13-inch Macbook (2006 model I believe) along with a handy mini-DVI - VGA adapter. I used a Hanns-G HU196D external monitor which worked fine for a couple of months but then stopped, and had the same problem with a (much cheaper) 'LiteView' monitor. I find it bizarre how they work absolutely fine and then stop, with no damage to the adapter, cable or ports. I've since bought a new adapter and cables + trying out a different monitor and still the same problem...
I've installed a firmware update that describes the exact symptoms, but it's done nothing. Can anyone help me resolve my issue?? It's still under warranty so is it an unusual problem that'll need to be fixed by Apple?
Thanks

Are you using the mini DVI to DVI followed by a DVI to VGA adapter? That may not work if the mini DVI to DVI adapter does not pass analog video. If that is the case, you need the mini DVI to VGA adapter:

Resolution problem with Mini DisplayPort to DVI Adapter

Hi,
I have a unibody MBP 15', running on 10.5.8. I use 'Mini DisplayPort to DVI Adapter' (http://store.apple.com/us/product/MB570Z/A?fnode=MTY1NDA5OQ&mco=Nzk2MDk5OQ) to connect to my external HP LP3065 30' monitor. I get max resolution of 1280 x 800 for external monitor which supports resolution of 2560 by 1600.
This monitor used to work fine with old MBPs, but not with my unibody MBP. What could be the problem? Adapter or MBP?
I am missing high resolutions
Thanks in advance!
Rohit

You have the wrong adapter. The one you have is single-link DVI, which does not support 30" displays. You need the Mini DisplayPort to Dual-Link DVI Adapter:

Mini Displayport to DVI Adapter Problem on Mid-2009 Macbook Pro

I have a new mid-2009 Macbook Pro hooked up to a 20" Samsung 2033sw LCD with a native 1600x900 resolution using a mini Displayport to DVI adapter that I bought off of EBay. No matter what I've tried I can't get anything to display on the external Samsung LCD higher than 1024x768. I tried switching between GPU's and that made no difference. Any ideas.?

Michael, thanks for the reply;
When you open System Preferences/Displays does a second preference panel open up OK on the Samsung ?
Yes, but I can't see it unless I select 'gather displays'. Then it appears on the MBP LCD, and showing the correct resolution - 1600x900.
Is there an Options Tab visible under which you can check 'Overscan' ?
None that I can find. Only display and color tabs.
Is the Refresh Rate set to 60.0 Hertz
Yes, that is what it shows in Refresh Rate.
I also pulled out an older LG LCD that is fairly generic, .e.g. it has DVI in at 1280x1024. Same problem on that LCD ... nothing higher than 1024x768, but this time at 1280x1024 I get major noise and screen distortion. The displayed image is jumping all over the place, but at least there is something displayed.

Macbook mini DVI to DVI output problems

hi
I've been using a samsung syncmaster 22" with my macbook for about a year now with no problems using the mini DVI to DVI connection
then earlier this week i used a different DVI cable to plug my playstation 3 into the screen, when i plugged the computer DVI cable back into the screen lots of red/pink pixels have taken over the screen and when the desk is nudged red lines flash up
i thought it might be either the DVI cable or the mini DVI to DVI adapter and replaced both to no avail, i have also tested all the cables on other screens/with other computers, and tested the screen with my playstation. Screen and cables all work fine so i think it must be some kind of output problem, but cant work out what it could be seeing as nothing would have happened to the port on the actual computer whilst changing connections on the samsung screen
sorry for the long winded post, really wanna know what the problem is here

Hi cbeth,
welcome to macbook forum.
For your friend macbook, try to press F7 back and forth to switch between mirror and expanded mode.
Try to update your macbook hardware firmware and software using software updater and repair permission after that...application/utilities/disk utility/repair permission.
Also reset your PRAM and PMU.
Open your friend system preference / display and try to compare and set yours similar to hers, including resolution, color depth, refresh rate.
Good Luck.

Mini Displayport to DVI adapter problem

Using a mini displayport to dvi adapter results in a jumpy mouse and a delay on screen when typing text. I've searched for days, but couldn't find the answer. I am using an iMac 27" i7 8GB and as additional monitor a Philips 220WS.
Can anybody help me?

I havent seen the text issue yet but I dont think I tried typing because I use the cpu with two screens for editing and I got frustrated and unplugged the second monitor. Ill try it and get back to you. Thanks for chiming in we need to get a solution to this as its one of the main features for me.
I wonder if we can call apple with this one as it seems to be a defect.

Problem with Mini DVI to DVI adapter

Hello friends Im trying to make my Mini DVI to DVI Adapter working with a projector but it appears that it's not working. It's seems a drivers issue because I've tried with one to Mini DVI to VGA adapter with the same computer and projector and it works fine. Is there any drivers to this device?? Thank you in advance

Problem: Mini DisplayPort to DVI Adapter with Samsung Syncmaster 2033HD

Hi,
I am using the Mini DisplayPort to DVI Adapter to connect to a Samsung Syncmaster 2033HD
However, I get No Signal with DVI as the Source.
It works when plugged into the DVI slot of the Mac Pro.
Any help would be much appreciated.
Chad

DisplayPort and its variant Mini DisplayPort, use a new and different protocol for communicating with your display.
A properly-functioning adapter can request the DisplayPort use "Dual-Mode", which produces a good approximation of single-Link DVI/HDMI. This is good for resolutions up to 1920 wide, which would include your Samsung (1600 by 900).
Wider displays require a more expensive "active" "powered" converter, to convert DisplayPort to Dual-Link DVI.
So if the display works with a straight DVI connection, but not a DisplayPort adaptation to "Dual Mode" DVI the weak link appears to be the adapter, but you cannot quite rule out the display card.

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

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.

Monitor won't work via mini-dvi to dvi adapter

It's a brand spanking new mac mini. I attached a 5 year old lcd monitor (always used before as VGA) using the mini-dvi to dvi adapter. I am using the monitor's dvi connector. The monitor resolution is 1280x1024.
The monitor does not work when using the mini-dvi to dvi adapter. If I remove the mini-dvi adapter and use a mini displayport to dvi adapter, it works just fine. I can keep both adapters plugged in and plug the cable into one or the other. It always works instantly when attached to the minidisplay port and doesn't work if I switch to the mini-dvi port.
I've tried the display with mini-dvi adapter on my macbook too. On the laptop, it acts like there are two screens attached, but there is no action on the external display.
As a further test, I attached the mac mini to the TV via a mini-dvi to hdmi adapter. The mini-dvi port on the mini works fine, as does the port on the laptop. The monitor works fine via minidisplay, but not mini-dvi.
Naturally, I concluded that the mini-dvi adapter was faulty. A second adapter came today, and nothing has changed. Could I have received two Apple mini-dvi adapters in a row with problems? Is there something about the monitor that doesn't like the mini-dvi port? It seems like it wouldn't like the minidisplay port either, but that one is fine.

• Went to Best Buy
• Paid for a DYNEX Mini DisplayPort to HDMI Adapter ($25)
• Came home and plugged in the adapter then the HDMI to DVI cable to the monitor. (Note: Monitor is a LG Flatron L22WTG) - DID NOT WORK
• iMac knows monitor is plugged in and I can change the resolution on both monitors and mirror. (Note: Changed to every resolutions with/without mirror image.) - DID NOT WORK
• Restarted computer - DID NOT WORK
• Turned off/on LG monitor many times - DID NOT WORK
• Unplugged/plugged back in many different ways - DID NOT WORK
• Changed the HDMI to DVI cable with a better cable - DID NOT WORK
• Installed BootCamp with Windows 7 - *BOTH WORK 100%*
• Rebooted to OS X 10.6.7 (Snow Leopard) - DID NOT WORK
• Installed Windows XP - *BOTH WORKED 100%*
• Reinstalled OS X 10.6.4 (Snow Leopard) - *BOTH WORKED 100%*
• Updated OS X from 10.6.4 to 10.6.7 - DID NOT WORK
Seems to be a driver problem with the new update (10.6.7). I will not update again till drivers are fixed.

Trouble with 30" HD Cinema Display using Mini DisplayPort to DVI Adapter

I bought a new MacBook Pro and I am having trouble getting the full resolution to work with my 30" HD Cinema Display (purchased in 2007 max resolution 2560 x 1600) using a Mini DisplayPort to DVI Adapter.
According to the specs page, http://support.apple.com/kb/SP581 , the max resolution of the HD external display is supported. Unfortunately the max that I can set it to is: 1280 x 800
Has anyone else had the same issue?
If this isn't resolved I'm likely going to exchange my MacBook Pro for one that can support this display.

So I went and bought the Mini DisplayPort To Dual-Link DVI Adapter as suggested and it seems to work great.
Now the problem that I have is when I open up Apple's DVD player, the screen is blank but I can still hear audio.
If I unplug the display, the movie will display properly. Rebooting with the display plugged in doesn't help either. I also deleted all the DVD players enc setting files so that they would re-initialize but no luck.
Any idea what this problem might be??

Mini-Displayport to DVI adapter not working, but Mini-Displayport to VGA and Thunderbolt work fine

Mini-Displayport to DVI adapter not working, but Mini-Displayport to VGA and Thunderbolt work fine.
This is a brand new MacBook Pro (15-inch, mid-2012) just received. I suspect that this is a hardware problem as:
The mini-displayport to DVI adapter and the external monitor that I am utilizing connect and operate just fine using my older MacBook Pro (mid-2010) with the same OS.
The new MacBook Pro powers the external monitor with a mini-displayport to VGA adapater without issue.
The new MacBook Pro powers an Apple Thunderbolt display without issue.
Both MacBook Pro's are running OSX Lion 10.7.4.
The only combination which does not work is the mini-displayport to DVI adapater used in conjunction with the brand new MacBook Pro (mid-2012).
All adapters and components (mini-displayport adapters) are Apple retail adapter.
I have tried several external monitors, including my Dell U2412m.
When I connect the mini-displayport to DVI adapater to the new MacBook Pro (mid-2012), nothing happens. The external monitor reports "no signal" and attempts to go into sleep mode. Using the "Detect displays" button has no effect, even when used multiple times. Rebooting does not help, nor does resetting the SMC or PRAM.
Any other suggestions before I take it to the Genius Bar?

I turns out that the logic board of my MacBook Pro was faulty (despite being brand new).
I took it to the Apple Store, presented the problem, and one of the Tech's came to the same conclusion that I had -- hardware failure. Phone support was no help in the matter (and even told me that what I was trying to do wasn't a supported option, which is rediculous). However, the Genius Bar did take care of the problem, and my MacBook Pro was back to me with a replaced logic board within a few days.
Hope that htis helps.
