Red static using Apple's mini-Displayport to DVI Single Link adaptor

Here's the problem :
The adapter from Apple I got is the 30$ (or so) DVI-D Single Link (nine pins active on the side with six pins non-active in the center).
My Dell 2408WFP monitor got two DVI-D Single Link connectors.
I did my test with two different cable : one DVI-D Single Link and one DVI-D Dual Link. Both cable are working just fine since I can hook either my older Macbook Pro Core Duo or my PC to the monitor using them.
But when I 'm trying to use my new Macbook Pro Unibody 13" with the mini-Displayport to DVI adapter I always get red statics : one pixel dots flickering randomly all over the screen. The picture is there, though, and my computer is able to recognize the display and its native resolution (1920x1200). Sometime, the display seems to lose the signal and shows only white noise.
Any idea, similar experience?

Thanks for everything,

Problem solved here, really. Nothing to do with Apple. Everything to do with Dell.
So I got a replacement monitor (a second one) from Dell regarding another problem with the Displayport connexion. It fixed this problem. I then tested the same mini-Displayport to DVI adaptor on this new replacement monitor : works flawlessly. No problem whatsoever. No static. No suddenly going in sleep mode. No random disconnection. So the problem was the monitor : EDID profile, maybe firmware. See below.
Here are more details which I got using SwitchResX. I hope it can help others for diagnostic.
The monitor that was ALL wrong was : a Dell 2408WFP, EDID version 1.3, product code 10912 (2AA0) (A02A) (which means, I think that it was REV A02A : you CANNOT rely on what's written on the sticker on the back of the monitor for that info especially when you get a replacement monitor, use SwitchResX).
The new monitor that is WORKING (with everything : Diplayport connexion as well as mini-Displayport to DVI adapter) : a Dell 2408WFP, EDID version 1.4, product code 11168 (2BA0) (A02B) (so I guess is REV A02B).
Notice the difference in the EDID version AND in the REV version.
If you have a Dell monitor, same model (2408WFP) and are experiencing problems with your connexions, check those info, call Dell for a replacement.
Thanks for all your feedback and suggestions. I'll post this on Dell forum as well.

im running OSX 10.7.4

Hi There,
I have had the exact same issue but with a projector.
The issue lies with Mountian Lion 10.8.2.
I tried many a combination with no luck to get HDMI working.
Took my mac into the apple store and came to the conclusion it was the software, so I asked them to install 10.8 onto it (this is destructive so a backup is a must)
Bought my macbook home and voila, now displaying through my projector.
There is a small graphics update after 10.8.1 which seems to be the cause.
Hope this helps.
Thanks.

Mini DisplayPort to DVI Adapter failure misdiagnosed

When I purchased my new MacBook Pro last December, I had to purchase Apple's Mini DisplayPort to DVI Adapter in order to continue using my Apple 20" Display monitor with it.
Turns out the Mini DisplayPort to DVI Adapter dies so I no longer had access to use of my Apple 20" Display monitor
Only the cause of the display's going blank was not clear
I took my MacBook Pro and the 20" monitor tothe apple store Genius bar.
Using my computer and my 20" monitor, the Genius tried making it work with my bower block and with another one in the store. Nothing worked.
What he didn't test was the Mini DisplayPort to DVI Adapter itself to see if that was the problem.
So I bought a new monitor and that didn't work either.
I had to go back to the Apple store Genius bar a second time for them to figure out that it was the Mini DisplayPort to DVI Adapter.
Big PITA (Pain in the A..)
Poor diagnosis the first time gave me 10 days of frustration.
What's with that, Apple?
Steve

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.

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:

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.

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 is actually DVI-D? *** Apple!

I just purchased a new MBP (and I love it), along with an Apple Mini DisplayPort to DVI Adapter. I figured whatever monitor I wanted to plug into, if it was VGA, I could just stick a DVI to VGA adapter on there. Turns out, this adapter only supports DVI-D (digital only). A little fact that Apple fails to mention in their product page.
What a rip.
That said, does anyone know of a REAL MDP to DVI-I adapter? Do I need to buy the dual-link adapter?

They do say that it is for a "digital monitor, ... that includes a DVI connector."

No.
Do I need to buy the dual-link adapter?
If you are going to use a 30" DVI display. It's still DVI-D (but dual-link). It will also work with single-link DVI displays.
For a VGA display you need the Mini DisplayPort to VGA adapter

2009 24-inch iMac 3.06GHz (EMC no. 2267). I don't get any audio when connecting my Sony HD TV to my iMac via mini DisplayPort. Is there a fix or hardware upgrade? I'm using a Kanex Mini DisplayPort to HDMI cable w/ audio support.

You can connect the audio from your iMac to your TV using a mini jack (like headphones plug) to rca (regular red and white audio connectors used on every TV,DVD, etc) cable.
On your TV, you need to be able to set the audio for the HDMI input you will use to "analog" and connect the rca end of the cable to the analog inputs on your TV.

Is an Apple ACTIVE Mini DisplayPort to Dual-Link DVI Adapter the same thing as an old Mini-DP to DVI adapter?

Is an Apple ACTIVE Mini DisplayPort to Dual-Link DVI Adapter the same thing as an old Mini-DP to DVI adapter?
Will a different adaptor give me better resolution between my old computer and a new monitor?
Computer: MBP 15-inch Mid 2010
Monitor: Dell U2713H
Current cable: 20276 3dv ft1 DVI Digital Dual Link with a Apple Mini-DP to DVI adapter to get it to plug into my MBP.
Possible solution?: Apple ACTIVE Mini DisplayPort to Dual-Link DVI Adapter instead of my old adapter above?

Yes. A single-link DVI connection can't drive that monitor at its maximum resolution.

How can I set up a second monitor using the DVI, a mini Displayport to dvi?

Hey guys,
In my office I'm trying to set up a mac with two displays, Samsung screensync sa450s, using a Startech MDP2DVIW mini displayport to dvi, and the DVI port found on the ATI Radeon HD 5770.
However, whichever monitor is plugged in through the mini displayport never shows video, and instead will just flicker sometimes, no matter which monitor I use, or which of the mini displayports i use. The system profiler recognizes both monitors, and has all of the specs on both monitors, but only the monitor connected directly to the DVI displays anything, even if it is the secondary monitor.
The StarTech does still work with the macpro that used to be in this spot, and the only salient distinction I can find is that the old computer has Mountain Lion, while the new one is still running Snow Leopard. Is this a case where we should just update the OS? or is there another fix?
I've also read online that many people have been not fully plugging in these mini displayports, so I'm worried that I'm doing that, but then I'd figure it wouldn't have worked when I plugged it into the old computer unless my predecessor had made some hardware adjustments.
Let me know.

A frequent solution to problems like the one you describe involves pushing in the Mini DisplayPort cable-end.
It should be inserted until essentially ALL of the metal end disappears inside the jack on the 5770 board.
Is this display wider than 1920 wide?
EDIT: The Startech MDP2DVIW adapter you cited is a passive adapter suitable for 1920 wide or less. You should be using ACTIVE adapters, about US$35. They cost a little more, but are much more trouble-free. The ACTIVE designation means they contain booster circuitry to raise the Voltage levels up to true DVI levels. The default converter produces good timing, but the signals are really low.

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.

Does Mini Displayport to DVI adapter support analog VGA signal?

I'm just about to buy a macbook pro. Since the MDP (mini displayport) to DVI and MDP to VGA adapters are £20 a pop, I can only afford to get one. Obviously DVI is better in general, but VGA supports more older hardware, CRTs, and the spare VGA input on one of my displays (where the desktop uses the DVI).
What I'd like to know is does the MDP to DVI adapter also support the analog VGA signal on certain pins (like most physical desktop DVI ports do)? If it does, since I have about 3 or 4 DVI to VGA adapters lying around, I can get the MDP to DVI adapter and use the DVI to VGA adapters with it if necessary, but if it doesn't I might be better off getting the MDP to VGA...

No. Unlike DVI, which in the DVI-I configuration has both digital and analog pinouts, DisplayPort (and mini-DisplayPort) are purely digital. Mini-DP to DVI then DVI to VGA will not work. If you look carefully at the Apple Mini-DisplayPort to DVI adapter, you'll notice it's a DVI-D connector - digital pins only.
The Apple mini-DisplayPort to VGA adapter contains a digital-to-analog converter.
So, you'll have to choose. If you want VGA, get Apple's mini-DisplayPort to VGA adapter.

Mini DisplayPort to DVI + DVI to VGA Display Adapter, will it work?

Hi,
I have a MBP, and I have just purchased an apple Mini DisplayPort to DVI adapter.
I want to connect it to a VGA port.
Can I buy an Apple DVI to VGA Display Adapter and connect it to the connector above.
Will that work? Any one with experience who could advise me on that?
Thanks.

This does not work, because the Mini DisplayPort to DVI adapter has a DVI-D port that transmits only digital signals. VGA uses analog signals.

Mini Displayport to DVI working in Bootcamp but not in Leopard

I've got a new unibody MBP together with a mini displayport to dvi adapter.
When I connected the dvi cable with the MDP2DVI adapter to my new MBP and my 3-months-old Benq 20" LCD monitor, nothing shown up no matter how I tried. The monitor just kept saying no signal could be detected.
Being frustrated so I did some googling, and I'm surprised by the vast number of people who have got problems with the external display!! I really didn't notice this before I decided to buy this MBP and I'm a little regretted, coz the 2nd monitor is so essential to the productivity of my work...
After searching around for a solution for some time, I am pessimistic of waiting for a solution from apple as I see some people had already address this issue in late 2008 but till now seems no solution had came out.
Last night when I use bootcamp to enter Windows XP, surprisingly it can recognize my external display!!! So now I am quite sure that it's the problem of Leopard but not the display hardware nor the adapter nor my monitor/cable. Did anybody have the similar problem as me tried this in bootcamp??

keepyourpower,
For what its worth I've been having much the same issue with my Macbook Pro. Leopard will refuse to see the external display while Windows Vista on bootcamp 90% of the time will but not without some effort. I've been able to get Leopard to use the display after going in to Windows and manually selecting display attached in the display properties menu. It doesn't always work but it will sometimes.
I'm 100% sure there is a flaw in the logicboard on some of the 2.4 Ghz that is causing this issue. I recently sent my portable in for repairs and they replaced the display which is why it was in and the Logicboard. I'm not sure why they replaced my Logicboard nothing was wrong with it, but with the new one its having much the same problem as you. As I said before I'm 100% sure this is a hardware defect in the Logic Board and if you are within your 14 day return window I'd see about asking your local Apple store to exchange the unit for a new one.
Not really sure if this will help you at all but didn't want you to think you were alone with this issue..

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.

Mini DisplayPort to DVI issues

I just recently purchased the new aluminum MacBook, having previously owned one of the very last iterations of the white MacBooks.
With my old white MacBook I had purchased a Mini-DVI to DVI adapter, and was using that to connect to a DVI to HDMI cable, and that cable was going into my HDTV. I would select and check Overscan under the Display Options of my HDTV, which appeared as PDP-xx50SX under my MacBook, and two black bands would be added to the top and bottom of my MacBook's display, and I would get a full screen crisp image on my HDTV that I was very satisfied with, I would use this to view TV Shows and Movies on Hulu without any issues.
I no longer have that MacBook as a few days ago I got my new aluminum MacBook, and with it my Mini DisplayPort to DVI adapter. 4 hours ago I wanted to catch up on The Office, so I plugged in my new adapter to the Mini DisplayPort, hooked up my DVI to HDMI cable, and that into my TV, just like I did with my previous MacBook. That was 4 hours ago, and I am still unable to properly configure it like my last MacBook.
I have been beating my head for 4 hours now looking across every forum on the internet, every thread, and every possible way to type out this issue on Google to find any and all results. For some reason I just do not get the Options tab like I was able to on my old MacBook where I could then select the Overscan checkbox.
This is really frustrating, I've tried every possible combination of resolution, mirrored and not, and nothing works like it did with my old MacBook. I simply cannot get a correct full screen image on my HDTV.
Is this a firmware issue? Has it already been addressed and I somehow missed it? Is there any fix? Is this the cause of DisplayPort? Why wouldn't nVidia's 9400m be able to do the same thing Intel's GMA X3100 did? So many questions, and I didn't know where to turn to so I came here to the Apple Support forums hoping I'd get some resolution or reassurance this is something that will be/is being addressed. The only fixes I've seen online are programs like SwitchResX or DisplayConfigX, but I'm not that technically savvy and would rather not fry my screen, especially when it worked perfectly out of the box with my older MacBook. Help!

I am also frustrated by the new display port. I have purchased a DisPort to DVI connector from the Apple store and the pin configuration is different than previous all other Apple adapters (DVI-I). The 4-ins around the blade are missing in the new adapter. The genius bar said in Orlando that the new adapters are a new version of DVI called DVI-D. So all my previous investment cabling is hosed. I was away from the home 20 so I purchased yet another $29 VGA adapter from the Apple store to complete my mission.
Moral of the sad story - Buy a DVI-I to DVI-D adapter if you own and use a MacBook for presentations. The Apple Store does not carry them.
Hey wait a minute is this tied to the disappearing Firewire connector???
Mike
PS - I was ablt to find a DVI-D to HDMI connector that I will try when I get back home...stay tuned!!
