Running a 27 inch monitor over Dual link DVI-D

Hi all
I have recently acquired a 27 inch monitor to use with my Mac.
My Mac is a 13 inch 2011 Macbook Pro.
I am connecting using the Apple Dual Link Adapter.
When I connect and boot-up, I get the grey background with the Apple. No problem. But when the bootup is complete, the picture has disappeared. This leads me to believe that the problem is a OSX problem. I have the latest version of OSX lion.
When I use the same monitor and adapter on Windows / Boot camp, it works flawlessly. More reason for me to believe that it is a OSX Lion problem.
Any solutions?
Thanks

I happened onto this thread while searching for a way to connect my T400 to my wife's 27" iMac. What I learned thus far is that Atlona makes a device (AT-DP400) that will convert dual link DVI to Mini DisplayPort. But Atlona says that one's graphic card must support 2560x1440. The T400 doesn't have a DVI out (nor does my current docking station), but it sounds like one can get a docking station that does. But that won't help if my card won't support 2560x1440. So are you saying that there is no way I will be able to use the 27" iMac as a monitor for the T400?

How do I get my Macbook Pro 15" to run dual monitor setup with Dual Link DVI outputs

I own have two 27" 2560x1440 WQHD LED IPS Computer monitors and have been trying to get them to work with my macbook pro 15" w retina for over a month now. I have purchased multiple products and nothing has worked. The big problem is that the only input that the monitors have is a Dual Link DVI input. The closest that i have gotten to getting them to work was this morning when I bought 2 Mini Display Port to Dual Link DVI Adapters for $99 a peice. Below is a link
http://store.apple.com/us/product/MB571Z/A/mini-displayport-to-dual-link-dvi-ada pter?afid=p219%7CGOUS&cid=AOS-US-KWG-PLA
Problem is that when I hook them up, I still only get a picture on one of the screens. Also, it requires you to plug into a mini Display port and USB port which takes up all of the space for me to run any othe peripherals. Though it has a built in USB port, when I plug my apple keybaord into it, I get an saying "USB Device Needs power, connect "keyboard Hub" to power or usb port on this mac"
I have looked everywhere for a docking station that would satisfy my needs, however, it does not exist. I use my macbook as my main office computer and take it home with me every night. I switched from the lenovo thinkpad to the macbook and have been satsified with my decision except for the fact that i cannot connect my monitors to it.
Please help!

Yes, that would work, however it would cost me $2000 for the monitors.

Can I run two 2560x1440 monitors (dual link DVI) on a new Mac Pro?

I have two Monoprice Zero-G IPS monitors, which can run at resolutions of 2560x1440 using a dual-link DVI adapter. This is what I am currently using on my old 2008 Mac Pro.
If i get a new model Mac Pro, could I continue this arrangement at the max resolution by using two Thunderbolt/Minidisplay port to Dual link DVI adapters (and, I assume, using two of the USB ports as I do now)?
Frankly, I dont need the power of a new Mac Pro but my old one is long in the tooth. I'd get a retina Macbook and use it as my desktop, but I cant think of any way to run both monitors at full resolution on the Macbook Pro. I dont want to run them at HDMI resolution.
Thanks in advance!

Adapters go from $9 to $54, the latter having heat-sink which is not needed in an open cMP.
Some support both as in either or but not two at the same time, SATA interface on the PCIe afapter, or an M.2 type
While other PCIe "solutions" exist they are not OS independent or machine, the XP941 suffers from none of those concerns as it is bootable in all Mac Pro 1,1 thru 5,1, and is the only one for 200-7 models (and 2008 are iffy) so you can 'take it with you' if you move to a new cMP.
Old controller, you need two SSDs in RAID0 to get 900MB/sec writes.
Does not appear to be any of the real issues of PCIe slot and bus master, outside of you would exclude the 1x slot in the 2006 of course!
The hardest part? getting these tiny M.2 blades, which are ~ 1" x 3.25" and have a tiny screw, on the PCIe adapter.
250GB SSD today are ~$120 + many do want SATA III PCIe (to get 550MB/sec and allow continued use of 4 x SATA II drive bays) runs ~$80-299. In some cases you then need a 2nd SSD. So if you want speed (vs size) then $240 + $100 and the $300 for XP941 256GB isn't bad.
Finally, look for an Apple blade on ebay if running Yosemite - they vary, some are 2x (slow) M.2s and you want 4x but any are probably 700MB/sec and cost $400-700. No need with Apple part to worry about TRIM.
Comparing 128GB SATA II $83 + $15 adapter vs PCIe XP941 128GB $140 + $24 is a 'toss-up' in cost but not performance, and one frees up drive bay and uses PCIe slot. (Generally 250GB are faster and better, the 128GB use to have 135MB/sec writes and $40 extras for 550MB and double storage makes sense, you never want an SSD to get down to 20% free, and you want to have 11% set aside for over-provisioning).
So in a way you can get 1000MB/sec like nMP for $175-300 in any Mac Pro, and new faster blades are on the horizon offering 1400MB/sec.
Kind of amazing, that M.2 support is in that old EFI all along waiting

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

Will my Airbook (11" late 2010) w/ NVIDIA GeFORCE 320M 256MB using the Mini Display Port to Dual-Link DVI Adapter support the Dell 3007WFHC (30") monitor at full resolution (2560X1600)

Works fine at 1280X800 (with out without MDP DL DVI Adapter) - cannot get any higher resolution

Hi ddickson01,
The MacBook Air 11 inch late-2010 model does support 2560 x 1600 resolution on an external display. See this specifications article for reference -

Macbook air to dual monitors (DVI and dual link DVI)

Hi i have MacBook Air (13-inch, Mid 2013), which only has a mini-displayport input.
i have these two monitors, one monitor has DVI, VGA, HDMI, and the other monitor has only Dual-link DVI-I.

Connect to Dual-Link DVI-D port on monitor using DVI-D to VGA adapter -- getting no signal

I have a T400. I am trying to connect to a dual-link DVI-D port on my LG monitor via the VGA port on my T400 laptop. I bought a DVI-D to VGA adapter, but I am getting no signal.
Do I need some other method or adapter or cable? Monitor works fine for VGA to VGA connection.
Solved!

Best way to connect T430 to Dual Link DVI 2560x1440 Catleap monitors?

I have a T430 and I am looking to get one of those cheap $300 27" Korean 2560x1440 IPS/PLS monitors, but the problem is all of the cheap models only take dual link DVI, while the new T430 notebooks only output via displayport.
I was thinking the best solution for this would be to buy a Lenovo dock that natively outputs dual link DVI (DP to dual link DVI adapters do not allow for refresh rate overclocking). Though on the Lenovo website they don't specify whether their docks output single or dual link, and I am not sure if the signal conversion is done "natively" or via some custom chip in the docks which might prevent refresh rate overclocking. Do you guys know of any T430 docks that are definitely equiped with native dual link DVI? If the docks are only single link DVI or do not allow overclocking then that leaves either buying a $70 adapter and forgoing the overclocking or buying a significantly more expensive monitor with displayport input (and more input lag).
What have your experiences with connecting your T430 to one of these monitors been like? And what do you think would be the best solution at the moment?

The dock dvi is single link dvi-d, if you wish to use dual link dvi-d connection, then you should consider the Apple laptop's active miniDP to Dual Link DVI-D converter.

How do I connect dual link dvi to hdmi so I can use my TV as a monitor?

I have tried to google this for some time and have gotten nothing but conflicting responses. I have a 15" macbook pro with a dual link dvi port. I want to connect it to the hdmi port on my HDTV. What do I need to make that happen?
Is there actually an adapter from dual link dvi to hdmi or will I need multiple devices for this?
thank you,
John

Hi there,
Thanks for the response...I think I have a 2007 version. My output is the DVI-I. It looks like maybe the dvi-i male to hdmi female might work? I don't see much in the way of dvi-i, there are more dvi-d around it appears.
This or many others like it will work, then a standard HDMI cable.

No Video from Mini-DisplayPort or DVI, only Dual-Link DVI

Just got my new Mac Pro 6-Core delivered. Out of the box, there were problems. I have a Dell 27" monitor that takes Dual-Link DVI, DisplayPort, or HDMI and a Dell 22" monitor that takes DVI, VGA, or HDMI. I am using a DisplayPort to Mini-DisplayPort cable to connect my 27" monitor to the Mac Pro and a DVI cable for my 22" monitor. I have the ATI 5870 graphics card installed OEM.
The problem is that the graphics card appears to not be switching to Mini-DisplayPort or DVI for output. It only works when I plug in a Dual-Link DVI cable to my 27" monitor. At that point, I get a video feed on my screen on a hard boot. At this point, I can then plug in my Mini-DisplayPort cable to my Mac Pro and unplug the Dual-Link DVI cable, and it switches video feeds perfectly. The problem then is that when I restart the computer, or power off and power on, the problem starts all over again. I HAVE to boot using the Dual-Link DVI cable for anything to work.
Ideas? Called AppleCare, waiting on engineering to see what they have to say. All the cables work perfectly when I plug them into my MacBook Pro (Late 2008). I am stumped.

I seem to be having similar problems. I bought the same system (6-core Westmere with the 5870 graphic card installed OEM) last month and I seem to be having problems running two Dell monitors which I know to be perfectly fine.
For the past month, I've been using a 24" Dell U2410 monitor with my Mac Pro using a DVI cable. Absolutely no problems at all. I then purchased another 24" Dell U2410 with the intention of running with dual displays. To prepare for this, I bought two mini-DisplayPort to DisplayPort cables from Monoprice. When I finally received the second display, I turned off the computer, hooked up both monitors through DisplayPort using the two mini-DisplayPort connections on the graphics card and turned on the system. I got two black screens. I tried to use keyboard commands to bring up the shutdown dialog box but it wasn't working. So I was forced to do a hard shutdown by holding down the power button for 10 seconds.
I went through a series of combinations of power cycles for the displays and computer and still two black screens. Finally, I went back to square one, a single display through a DVI cable. Again, a black screen. At this point, I disconnected the display from the computer. Power cycled the display (this initiates the self-test for the Dell display), hooked it up to the Mac Pro, turned it on, and it worked. I had one working display. Then I plugged in the second display using the mini-DisplayPort to Display port cable and that worked also. Finally, two working displays. For some reason, the Mac Pro recognized the display using the DisplayPort as the primary monitor. I rebooted the Mac Pro and the monitors continued to work properly. I booted into Windows 7 and again, no problems. I went back to OS X and used the computer for the night. When I was done, it put it to sleep.
This morning, when I tried to wake it up, same problems. I had to go through a series of power cycles and cable swapping to finally get a single screen to work.
I went through some of the troubleshooting documents here in the Support area and found this one:
http://support.apple.com/kb/HT4279
I am going to pick up the Apple mini-DisplayPort to DVI adapter and try running the display as two DVI monitors. Hopefully this will fix those problems. If the AppleCare engineer is able to give you anymore information, please let us know. This is a worrisome issue.

Apple's Mini Displayport to Dual link DVI Adapter... What to do?

So i'm doing a new setup with 6 monitors (Eyefinity 6), and i've got everything set up so far... Except for adapters. So i went and got 4 Of those Accel MDP to DVI SL adapters, in addition to the two passive that come with a card. Didn't work...
So i got two Apple Mini Displayport to Dual Link DVI Adapters... And boy, I should have read the reviews before buying them. They are giving me very strange issues. Not going above 800X600, serious graphics corruption on the monitors connected to the apple adapters, or odd resolutions that the monitors do not support.
So i'm wondering what to do. If possible, i'd like to get these to work somehow, as i got them for cheaper than other MDP to Dual Link adapters. They are both plugged in to the USB ports of my mac pro.
I've also heard something about a firmware version, 1.2 or something. Is there a way to update the firmware of these?
Thanks
-C

I'm using the Sapphire 5870 Eyefinity 6 Edition. Two of them in crossfire, supplied their power from an external 1200W PSU Devoted just to them.
It's under Windows 7, running on my mac Pro 2.26.
Hooking them both up to a iphone cube-wall charger keeps them up and running, but they fail to supply the necessary resolution (One only registers 640X The other dimension, the other thinks the monitor is 1920X1080, when it really is 1920X1200).
Not to mention, attempting to use any of them in an extended desktop led to a MACHINECHECKEXCEPTION bsod.
I can't find any sign of what the whole issue is, i'm having issues with the eyefinity setup itself too, so i dunno if its the adapters, the card, drivers, or what. The apple adapters are acting up on me though.

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.

HT1338 Dual Link DVI Adapter Doesn't Work

I have a brand new MacBook Pro with Retina which replaced a 17" MacBook Pro. The 17" machine was connected via an Apple-branded Dual Link DVI adapter to a Dell 30" (2560 x 1600) external display - the best I can get the MacBook Pro/Retina to do is 1600 x 1000 using the same adapter that the 17" was using.
I have run all system updates - including one that was targeted at stability/support for external monitors - still cannot get better than 1600x1000 resolution.
Any advise?

Didn't find this answer on a general search, but once I submitted my post, the MORE LIKE THIS bar (right side of screen) showed up and gave me the answer! See below:
Update from Applecare: this problem made its way to engineering and they pointed out a 'hidden' way to fix this with no special 3rd party software:
When you bring up the resolutions for a given display, as its set to 'best for display' hold down the 'option' key while clicking 'scaled'. The scaled menu should now show all the resolutions supported by the monitor. On my Dell it shows 2560x1600 and everything works fine when I select that.
I held down OPTION and re-clicked SCALED; all resolutions came up and I'm now good to go!

Why does thunderbolt/mini displayport to active Dual Link DVI apdater not work on Osx Lion 10.3

Hi I am using a Korean IPS display PCBANK 27 Inch on my Macbook Pro Late 2011 with OSX Lion 10.3
I am currently using a Official Apple Displayport/Thunderbolt -> Dual Link DVI D Adapter.
When I use a windows 7 boot cd it powers up the monitor and it displays. When I use a Linux Live CD it boots the monitor up and displays at full resolution.
When I use Osx Lion 10.3 it does not even detect the display at all which quite odd.
Can anyone help me trouble shoot.
I went to options and screen settings and tried detect display it comes up with nothing :S I am thinking it has to do with APPLES ATI drivers? perhaps? I have a 6750 HD.
Anyone ?

Above mentioned graphics card can only go as high as 2048 x 1536 where the 27" Cinema Display does 2560x1440 by native. Atlona's AT-DP400 will only pass the given resolution through the display and won't be able to reach to the maximum supported resolution and 1280x720 will become the next available/supported resolution by the monitor. Atlona makes another model of signal converter which also scales to the native resolution (2560x1440), Model#AT-HD620 which will work the best for your setup.
