Intermitent blank / garbled external dual link display on MBP15

Hi have a early 2011 MBP 15.
I got a 27 inch Dell u2713hm display
Every few ours, the display goes blank for about 5 secondes.
Most of the time, it comes back normal. But somtimes it's garbled ( has colored noise over the usual image ).
When this happens, I unplug and replug.
I already changed the dual DVI cable.
Dell wants me to try the screen on another machine. But I don't have any other device that supports this resolution, while it works fine with lower resolutions.
And apple doesn't believe me unless I can show it in front of them. The diagnostic tools are not reporting anything wrong.
Anyone had a similar issue or have suggestions on how to go about this?
Thanks

Also, when I checked information on thesed cables on Amazon, a listing for a Cable Matters cable says this:
Overview
* Macs made before 2010 are NOT able to output audio over Mini DisplayPort.
* Thunderbolt™ Port compatible
My Mac is mid-2009.

Dual Link Display Issue on 30" LCD

Can I use "Mini DisplayPort to VGA Firmware Update" to my "Mini DisplayPort to Dual-link" cable?
Or this update is only for "Mini DisplayPort to VGA" cable?
(update URL ; http://support.apple.com/downloads/Mini_DisplayPort_to_VGA_FirmwareUpdate)
Now I have flickering and swaying display issue.
(Mini DisplayPort to Dual-link cable + DELL 3007WFP 30" LCD Monitor)
So I hope this update can be solve my problem.

there are several threads open on this - all stem from problems with the adapter cable (MB571Z/A)
here's one:

I have the new Mac Mini and a 30" Apple Cinema Display - basically, it 'works' but there are many problems - screen blinks & resolution degrades intermittently, screen saver sometimes crashes into a scramble, and sleep sometimes becomes coma.

I am trying to add 2 External Dell monitors to my Macbook 13" Air. Will the Mini Display port to Dual-link DVI adapter work? If not what do I need in order to add 2 external monitors?

I Just bought a new 13" Macbook air and want to add 2 external monitors. Am wondering if the Minin Display Port to Dual Link DVI adapter will work. If not is there any other solution to add 2 external monitors to a MacBook Air?

nice, it's always the ones that fail to do a basic search that are the most hostile. i'm sorry you thought my asking you what monitor was 'drilling' my crystal ball was broken at the time.
there are TONS of posts and articles out there with your answer, but since that may be too hard for you, i've provided some here.

Switching between Dell 4K display and Apple Mini DisplayPort To Dual-Link DVI Adapter

Hi All,
I've recently upgraded my home setup to a Dell 4K display (Dell P2815Q), which since the 10.9.3 update work as expected.
However the downside is that my office setup uses a Mini displayport to Dual-Link DVI adapter (Firmware version 1.03) and a Dell 30" display (2560x1600), which will not work without a reboot after using the 4K display. If I use the 4K display after using the Dual-Link DVI adapter it works fine.
Is this a know issue ? If not, I'm happy to provide some more diagnostic information to help resolve the issue.

http://www.everymac.com/ says:
*This model supports a simultaneous maximum resolution up to 2560x1600 on two external displays via Thunderbolt. Alternately, it can support a single display up to 2560x1600 via Thunderbolt and a single 1080p display at up to 60 Hz, 3840x2160 at 30 Hz, or 4096x2160 at 24 Hz via HDMI.
DVI is not mentioned at all. You probably need to connect to the display via HDMI to get the 4096x2160 resolution.

Why my new Mac mini DVI dual link mini display port adapter doesn't work with my 30"display (LG W3000H)?

Hello There
Can any of you advise on the below? Tried to connect Mac mini with a 30" display through a DVI dual link mini display port adapter. For the first try Mac mini go connected to the display, then i've chosen the highest resolution (2560x1600, native) and right at that moment they got disconected. Since then the display stays black. What can be the issue, is it possible DVI dual link mini display port adapter is not compatible with 30"display (LG W3000H)? It works with DVI male-male cable plus DVI HDMI adapter as long as the resolution stays under 1280x800. Any idea is much appreciated.
Thank you, Vera

Hi,
I can report that my Mac Mini Intel Duo connected instantly and without even having to set it up (on the first try) with my 1366x768 native resolution DELL 50" Plasma Display. It's so beautiful that I just want to stand there and fondle my HDTV as I drool haplessly like Homer Simpson with a doughnut in his mouth. Seriously, no problems.... guess I bought the right cable (ebay).
Before you buy a Duo, make sure you're aware of the airport and bluetooth issues that so many (maybe everyone who tries to use them together) are having. It seems that bluetooth interferes with airport, or maybe the other way around. Anyway, it's messed up. Also, Airport reception is generally VERY poor with the new Intel Mac Mini.
Despite these things, I still love mine (I now have 2 base stations and an airport express for my powerhouse wireless needs, and an external DLink bluetooth-2-USB dongle solved the bluetooth/airport issues... in my case).
FWIW,

17" MacBook Pro to 30" HD Display issue using Mini DisplayPort to Dual-Link DVI Adaptor.

Just replaced the Western Digital hard drive on my MacBook Pro with a SSD now running Lion 10.8.2, (updating from Snow Leopard latest version).
I have a 30" HD Apple display monitor and very much love using it.
The issue.
The MacBook Pro will only allow the 30" Monitor to display its top resolution when the unit is closed, when it is open it shows either 2 screens or mirrored screens depending upon the settings, but not at the top resolution capable by the monitor.
Now, when I was using Snow Leopard on the previos hard drive, I could close the MacBook Pro and put the computer to sleep also putting the 30" Monitor to sleep, I could then wake the computer while it was closed with my external keyboard and the screen would wake showing the FULL resolution possible on the 30" Monitor.
Then I could open the lid of the MacBook Pro and the screen would stay black allowing ONLY the 30" HD Monitor to be used effectively as a desktop computer, without the complication or need to display 2 screens or mirrored screens but most importantly the fans wouldn't need to work overtime due to the MacBook Pro being closed cutting off vital ventilation through the 2 air ducts to the left and right of the keyboard.
For some reason I cannot do this with Mountain Lion, the compluter needs to be closed in order for the 30" Monitor to display top resolution, and the fans are working overtime and the unit is getting really hot.
My concern is that the MacBook Pro will overheat, the screen will be damaged as the MacBook does get exceptionally hot when running design and audio packages, even Adobe Flash sets the fans off, and lastly the computers speakers are muffled which is more of a moo point.
If anyone could shed some light or offer a solution I would be most appreciative.
My specs:
MacBook Pro 17" Mid 2009 3.06 Intel Core Duo, 8GB 1067 MHz DDR3, NVIDIA GeForce 9600M GT 512 MB, OS X 10.8.2 - connecting to an Apple 30" HD monitor with a Mini DisplayPort to Dual-Link DVI Adaptor.
Thanks

Thanks for your quick reply! I want to think I'm not technically challenged, but... are you saying to go from minidisplay on macbook directly to the firewire in the back of the monitor? Or should I try to attach it to that ugly bunch of cables at the end of the monitor cable (dvi, usb, firewire and the power adapter thingy)? Either way, it seems like I might need yet another cable? Like Mini-display to... ?
I feel like my mother asking these questions... At any rate, when I called the guy at apple support last time he acted like it was a Miracle that I had anything on my cinema display at all if I had a minidisplay cable plugged into the thunderbolt port. He said that didn't work (but obviously it did, at least a little) I DID get a picture, it just wouldn't display at the 2560x1600 resolution. More like 1680xsomething. fuzzy and big. I want my pretty picture back.
Thanks so much for your help.

30'' Cinema Display with mini-display-port to dual link DVI adapter usb hub

Hi all, I don't know if any one of you experience this issue and can help me.
I am using an unibody macbook pro (late2008 model) to connect to a 30'' cinema display via the famous $100 mini diaplay port to dual link DVI adapter. I have connected the usb cable from the ACD to the adapter and the usb cable of the adapter to my macbook pro. This setting works fine under OSX 10.5.7.
When I am using Windows Vista under bootcamp the USB hub on the back of the ACD doesn't work. The device manager of Vista shows an excalmatory mark besides the device "Generic usb hub"; and it reports a problem of "the device cannot be started".
I doubted this problem is due to Windows cannot recognise the $100 adapter as a "generic usb hub"; and apple has not release a driver for this $100 adapter for windows.
Since my MBP only has 2 usb ports and the $100 adapter already occupied one, it would be very much helpful if the usb hub of the ACD can work just like in OSX. Can anyone think of any suggestion?
Much appreciated for reading this post and thank you.

i don't have an answer for you, but i feel your pain. very frustrating when this happens with Apple products and Vista/Bootcamp. wish they were more compatible, for it would make things so much easier for the consumer.

How to adjust the brightness of a second display connected to iMAC 2012 by Apple Mini DisplayPort to Dual-Link DVI Adapter?

How to adjust the brightness of a second display (Dell 3007WFPHC 2560x1600 dpi) connected to 27 inch iMAC 2012 through thunderbolt port by an Apple Mini Display Port to Dual-Link DVI Adapter?

Macs control computer by USB. With a non-Apple display, you will have to use the brightness control on the display.

Mini Displayport to Dual-Link DVI Issues on 30" Cinema Display

I know this problem has been around for a while, and that there are several other discussion on it, but my goal here is to point out that even in mid-2011, this issue remains.
Here's my configuration:
30" Cinema Display
Dual-link MDP to DVI adapter with 1.03 firmware (purchased August 2011 from an Apple Store)
New-ish MacBook Pro (purchased December 2010) with Mini Displayport
Symptoms:
On dark areas of the screen, DVI noise appears (horizontal flickers of light coming and going at random)
Attempted Fixes:
Unplugging the display and plugging it back in to the computer (failed)
Restarting the computer (failed)
Tightening the connections on the Dual-Link DVI adapter (failed)
Sleeping the display and awaking it (failed)
Some suggest getting a new 27" Cinema Display with native Mini Displayport/Thunderbolt support. I actually have one, but I cannot tolerate the glare on the glossy displays, so I'm "downgrading" to a 30" Cinema Display.
Is there any remaining hope for this issue?

I still cannot understand why you would return everything... Ultimately you want this computer right? Once the bugs on the adapter are fixed are you gonna go back and re-buy it?
Seems like a lot of time spent out of spite and not for good reason. Me, this is the best Mac I've ever owned (and I've owned many. no, really.) and I'm happy to wait for this adapter w/ this machine in stead of going back to my other box.
I observed a similar client of mine w/ an iPhone... after the first week, he didn't like the keyboard and a few other things, so he took it back and went back to using his Blackberry -only to dump the Blackberry again for the iPhone, because he realized that the iPhone still did more things better than the Blackberry.

Mini Display Port to Dual Link DVI Does Not Work Right

Somebody said here that this was an isolated problem. Well, I just got my new MacBook Pro 15", used the adapter to hook to the 30" Dell monitor, and it works a few minutes, then the screen distorts.
Count me among the isolated problems- it is beginning not to look isolated.
Now, do I wait on Apple to fix the problem, or do I return the MacBook Pro while still in the return period?

Hi, Matt, and welcome to Apple Discussions.
The Matrox Support only told me that the new MacBook Pro with Mini Display Port is not supported, but as it's working for 2x1680x1050 with the Dual-Link DVI adapter, I was wondering if the Mini Display Port to Dual-Link DVI Adapter could be the problem.
I suspect that what Matrox Support meant when they said "not supported" was, in fact, "not supported": i.e., they've tried it and it doesn't work satisfactorily. You've tried it too, and found that to be true. Now you just need to come to terms with the fact. Matrox is quite open about it; it's not a secret.

Mini Display Port to Dual-Link DVI Adapter: No image with 3840x1200

Hi!
I ordered the Mini Display Port to Dual-Link DVI Adapter regardless of the many complaints that it's not working in order to connect my new MacBook Pro to my Matrox TripleHead2Go. This Graphics Expansion Module normally allows to use two 1920x1200 monitors when connected to Dual-Link DVI (3840x1200). It works fine on my old MacBook Pro (with Dual-Link DVI output), but with my new MacBook Pro the first monitor just turns black and the second tells "Out of Range" when using the Mini Display Port to Dual-Link DVI adapter.
When I am reducing the resolution to 3360x1050 (2x1680x1050) it works, but this is not the native resolution of my two 24'' monitors and therefore is useless.
The Matrox Support only told me that the new MacBook Pro with Mini Display Port is not supported, but as it's working for 2x1680x1050 with the Dual-Link DVI adapter, I was wondering if the Mini Display Port to Dual-Link DVI Adapter could be the problem.
Any input welcome.
Thank you in advance.
Cheers,
Matthias

Macbook Pro with Retina wont detect monitor on mini display port to dual-link dvi adapter

So after reading Jeff Atwood's post, I decided to jump and give it a shot. So this week I got my monitor in from Korea, and I already had my Apple mini display port to dual-link dvi adapter, hooked everything up - and nothing. Monitor doesnt show a signal, and no display shows up in user preferences.
To verify the monitor actually works, i plugged it into my windows box - and boom, right away there it is in all its glory. So I called apple support, after spending about an hour going through the "are you sure its plugged in stuff", the tech finally admitted to being stumped and blamed the adapter. Not to be deterred, I then went to my local apple store and talked them into trying their adapter to rule out the adapter - regardless of the adapter, the mbp wont detect the monitor.
Just for fun, i tried my old single mini displayport to single dvi, the monitor is recognized, but that obviously cant drive the right resolution, so i just get a backlight. Same deal when i try the hdmi port with a hdmi to dual-link dvi adapter on the end of it. Also tried display port to the same hdmi with adapter on it (the joys of working in a dev shop - cables to test everywhere)
I have read / tried a ton of things:
re-installed / uninstalled air display, just to be sure it was gone. went through all my apps just to see if there is anything like this i could think would be effecting it
install gfxCardStatus to ensure i am on the nvidia (discrete) and not the internal card
Played with different settings on SwitchResX to try to force the res over hdmi - no love - os rejected each one
I bought the monoprice adapter wondering if it was just the apple adapter since the apple adapter has been panned, no love from it either
Reset the PRAM countless times
I have two other adapters coming in to test with in a day or two - maybe one of those will be magic, but at this point i kinda think its software on the mac. My Spec:
I am running Mountain Lion with all the latest updates
New MBP with Retina (2.6g processor, 16gig ram, nvidia video card)
Here is the ebay link to the monitor
Now the other weird thing is pretty much universally these auctions say the monitors cant be run on a laptop - which makes no sense to me, because its just a connection, if the video card is strong enough (which my machine better be) it shouldnt matter the source. The listing mentions its a "by-pass" monitor, which is something I and google have never heard of.
So any sage words to make my day?

Magic was, I have to have the adpter plugged into the mac, let it recognize all with the monitor powered off.
then power on the monitor, and boom gloriousness
For future generations, setup that works:
1) MacBook Pro with Retina
2) Monitor From Korea (example auction)
3) Accell Mini DisplayPort to Dual-Link DVI Active adapter (amazon)
4) Boot mac, plug in adapter, let it recognize the monitor, power on monitor

MiniDVI with Dual Link won't display after restart

I have a bizarre problem I can't find and hope to get some help.
I have a brand new late 2009 Mac Mini 2.53Ghz with 4Ghz of RAM running OSX 10.6.1 and Vista Ultimate 32bit via Bootcamp 3.0 drivers.
I have the Mini DVI Dual Link adapter so I can use my 30" Apple Display.
When I run Vista Ultimate, the display works fine, unless I run a restart to reboot Windows. When that happens, the mini seems to cycle just fine, but there is no video on the monitor. Sound works fine, and nothing seems amiss with the Mac Mini except that there is no video.
If I then cut the power to the Mac Mini (not a nice thing to do!), when power comes back it reboots and the display works fine with full video.
This must be some foolishness associated with the use of the Mini DVI output into the Mini DVI Dual Link adapter, but there is no other choice in the matter with the latest Mini.
Any suggestions?

I purchased the same computer: 2009 Nov 16, Mac Mini, 4GB RAM.
Computer runs great with the dual-link video adapter connected to my 30" Apple display.
I installed Boot Camp 3.0, Windows 7 32 bit (Business).
The video driver (by default is a 2006 Microsoft version) and only support a max resolution of 1600 x 1000 (aprox - sorry not in front of it at the moment).
I downloaded and installed the latest Windows 7 driver from nvidia to hopefully correct the problem, but matters worsened, with the max resolution dropping to 800x600. I backed out the latest Nvidia driver and am back to the Windows default - which is OK, but not nearly the resolution that I paid for and presently enjoy with MAX OS X.
Does anyone have a solution?
Thanks

Display port Dual link DVI to Gateway XHD3000

The *displayport to dual-link dvi adapter* I bought doesn't seem to work with resolutions > 1920x1200. My Gateway XHD3000 monitor supports upto 2560x1600 but I can't set this resolution in the system preferences. I have set my power setting to "+Better Performance+" hoping the other GPU would be used but still the same lower resolution.
I'm using the Dual-link cable that came with my monitor.
I actually have 2 systems exactly the same with this problem.

Here is what the Gateway Tech support had to say. *Very helpful*....punt!

Dear Emmett Bearden,
Thank you for contacting Gateway. I apologize for the inconvenience that you have experienced. If you cannot set the monitor resolution greater than 1920 x 1200 or up to 2560 x 1600, this may occur if your MacBook Pro does not support dual-DVI output, does not support this kind of ultra-high resolution, or does not have the latest video driver. I suggest you please first contact Apple's technical support, to inquire if the MacBook Pro supports this resolution, or if they have a workaround for this problem.
Respectfully,
Gateway Online Technical Support
Customer (Emmett Bearden) - 01/07/2009 12:26 PM
Using my Apple MacBook Pro I'm unable to display a resolution greater that 1920x1200. I bought this monitor for the 2560x1600 resolution. My connection is a dual dvi using the cable that came with the monitor.
