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!

Mini DisplayPort to Dual-Link DVI Adapter doesn't work on Battery Power

When I'm using the Apple Mini DisplayPort to Dual-Link DVI Adapter to connect a MacBook Air 13" to a 27" Display, it only works as long as the Power Adapter is connected. In other words

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.

Will the old 23" ACD work with the Mini DisplayPort to Dual-Link DVI Adapte

Will the old 23" ACD work with the Mini DisplayPort to Dual-Link DVI Adapter and the new MacBook Pro?
Apple Store says it is for the 30" only.

I'm not so sure about that. I'd say the jury's still out until someone gets one and tries to use it single-link.

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.

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

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. See the 9400M/9600MGT MacBook Pro entry in this compatibility table from Matrox's web site:

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.

Trouble Playing DVDs with Mini DisplayPort To Dual-Link DVI Adapter ?

So I went and bought the Mini DisplayPort To Dual-Link DVI Adapter for my 30" Cinema display to connect to my MacBook Pro.
I open up Apple's DVD player and 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??

You've probably fallen into the nasty pothole created by the advent of HDCP compliant graphics on Apple computers and a mishmash of older and newer Apple gear that does/does not support HDCP.
Ironically, if you were using an older Mac notebook (prior to late 2008), everything would play just fine because HDCP wouldn't come into play anywhere.
That is my guess as to what is happening.

MBP + Mini DisplayPort to Dual-Link DVI Adapter + 30" = blue flickering

Hi everyone,
I was wondering if anyone has found a solution to this problem? I use an Apple 30" Cinema Display and it worked fine with my Late 2007 MBP. Now I got a new Core i7 MBP and the Mini DisplayPort to Dual-Link DVI Adapter. At first all works fine, but after a while of use I get blue (and sometimes also green) flickering pixels in areas that are supposed to be black. This does usually not matter while working, but watching movies for example is completely unbearable.
I’ve read a few threads, but most seem to have different problems like 1/3 of the screen flickering or the external display going completely off for a second. That is no issue over here. It is just that the longer I use my setup the more flickering gets added. At first I thought I don’t suffer from this, because it goes from practically flicker-free to totally weird flickering when everything is in use for more than a few minutes.
I’ve set up the Computer Name screensaver. If I run it right after turning on my MBP all is fine. Running it again after 2-3 minutes of use shows the first blue pixels flickering. It does not need 30 minutes to arrive at what seems like more flickering isn’t possible anymore...
Any recommendations or solutions are really welcome!
Things I already tried:
- different USB ports for both the adapter and the Cinema Display
- other power outlets
- powering the adapter from a USB hub or via an iPod wall charger
Thanks
Björn

I would even try out crazy adapter combinations if there were any available...
At last! I’m quoting myself, because I finally found an alternative adapter which works! I have no more flickering pixels/lines. Black looks and stays completely black as it should! I can finally use dark backgrounds again and watching movies with black borders or dark areas is no longer a pain.
The adapter was very hard to get. It currently is not sold here in Germany and I got it off eBay where there was only 1 available. I’m happy, because I got it for less than 90€ which is even a little cheaper than Apple’s flicker-creator.
The adapter I now use is the Sapphire Active DisplayPort-to-(Dual-Link-)DVI adapter. It has a USB connector for power like Apple’s adapter. The only thing that’s added is the DisplayPort-to-Mini-DisplayPort cable since it is not available with Mini-DisplayPort. Here’s a picture of it:
Hope this helps others, too!

PS: This adapter seems to be normally meant for ATI’s GPUs in order to connect 3 displays which they call Eyefinity.

New iMAC to Dell 3008 using Mini DisplayPort to Dual-Link DVI Adapter

I just brought the new iMAC 27" iCore7. Previously I was using old MBP with dual link DVI to DELL 3008 and they did fine.
But Today I connect the Dell 3008 to my new iMAC using Mini DisplayPort to Dual-Link DVI Adapter...They could not work properly...
The dell shows images in red with flickers....
I've contacted the phone for help...and they said nothing could be done????!!!!!
Anyone could help??
THX

just update my progress...
I had made calls to Apple technical support center in HONG KONG for help...
To my surprise...they even did not understand what I was saying(Or just pretending...)....One interesting guy said I could take the new iMAC back to service center to change the 4850 display card to older version...or call DELL for help!!!!!
Fuxking Apple technical support center in HONG KONG
I was almost hopeless until I found a minidisplay port to display port cable in Circuit Assembly:
http://estore.circuitassembly.com/products/Mini-Displayport-to-Displayport-Adapt er-Cable.html
ONLY $14.95 !!
They sent the cable to me in 3 days time...and I hooked it up right away when I received it today...my Dell 3008 could display 2560 x 1600 normally again!!!!!
The problem is: Apple is still selling its FUNCTIONLESS Mini DisplayPort to Dual-Link DVI Adapter at high costing....sounds like cheating others....
What' s wrong with the Apple nowadays???

TS3232 I have the mini DisplayPort to Dual-Link DVI Adapter firmware 1.03 and I still have screen flickering issues

I have the mini DisplayPort to Dual-Link DVI Adapter firmware 1.03 and I still have massive screen flickering issues on a Mac Mini 2012.
I am using a Dell 30" monitor (it's the Samsung screen just rebranded) connected to a WD 4TB Thunderbolt drive connected to the Mac Mini.
The screen is usable for the most part when I've just started the computer (although today I started having issues after a fresh restart) but if even just the screen goes to sleep, or the computer goes to sleep and I wake it later, I start to have massive flickering to black and occasionally to snow.
The effect seems to be more likely to arise when I'm on heavy graphics-intensive websites or programs (eg, Tumblr feed with lots of GIF images or working in Adobe Premiere), but once it starts shutting down those programs has no effect, the screen keeps flickering wildly.
The problem improved after the 1.03 firmware upgrade (for a while it was flickering uncontrollably ALL the time and was virtually unusable) but it has not gone away.
Any suggestions would be very welcome, either for how to fix this issue or how to get Apple to, you know, let me TELL THEM that their adapter firmware fix has NOT solved the issue, since my phone support has expired. :/

I have a new Mini DisplayPort to Dual-Link DVI Adapter to allow my original Apple 30" Cinema Display to connect to the new Mac Pro. Shipped straight from Apple, it is firmware version 1.03. I've never had flickering issues, but the display will often go black (possibly after a screen power save) and not come back. when this happens I am still able to connect to and use the Mac via remote connection. But the only way to get the screen back is either to unplug the adapter and plug it back in to the Mac, or to shut down and power up the Mac. This may be a separate issue, so I'll also post it standalone...

Mini displayport to dual-Link DVI Adapter - flicker issue resolved

I have a late 2013 Imac 27 inch and I had a 30" Dell 3007wfp as my second monitor on the standard DVI adapter for a while at low resolution. I finally got off my behind and bought the mini displayport to dual-Link DVI Adapter... I was excited to see it in all it's glory. It immediately started flickering wildly and I thought I'd do some reading to see how I could resolve it. Pointers to making sure the adapter was version 1.03 didn't help.
http://support.apple.com/kb/ts3232
I already had it. I was getting ready to bite the bullet and just take it back when I decided to see if I had another DVI cable to swap the one I was using out "just in case". I found another one.. same length. Darn it. Then I noticed the DVI cable diameter I was using was significantly thinner than the one I found in my box of etc... What the heck? I thought.
Connected it and BOOM! Vivid colors, high resolution, no more flickers!! Issue gone. Happy days!
Thought I'd post this to possibly help the next schmoe who is in the same situation

Mini DisplayPort to Dual-Link DVI Adapter

Hi, I am using the Apple Mini DisplayPort to Dual-Link DVI adapter to connect my 30" Apple Cinema Display (Aluminum) to my MacBook Pro 13" Retina, I am passing through the Belkin Thunderbolt Dock, so I connect the Dock to the MBP via the Thunderbolt port and then I connect the Mini DisplayPort to Dual-Link DVI adapter to the Belkin Dock and then to the Apple Cinema 30".
One of the issues I am having is that with the Cinema Display I am working at 2560 x 1600 resolution, much larger than the native MBP resolution, I am also using my apps in Full Screen mode, so when I disconnect from the Cinema Display and go back to use the MBP the apps in full screen mode still are at a higher resolution than the native MBP resolution and they are off the screen. Is there a way to manage a profile with different resolution so the Mac OS will switch automatically resolutions?
Also does the Apple Mini DisplayPort to Dual-Link DVI adapter usb cable supports USB 3.0 ?
Thanks

Hey guys,
I found out an answer by myself...
The missing link : the MacBook Pro needs to be powered... as in you need to plug the charger in...
In conclusion, you simply plug everything, turn on the MacBook Pro, close the lid, and there you go !

What does the 'Dual' in Dual-Link DVI Adapter refer to?

We purchased a 'Mini Display Port to Dual-Link DVI Adapter thinking it meant we could split the output to two monitors such as the Matrox TripleHead2Go or Matrox DualHead2Go.
Having received it, we are unable to determine the advantage of using this product other than a normal Mini to DVI adapter. Hopefully the Dual doesn't refer to the addition of a USB port. Thanks for any replies.
--Bruce D. Meyer

DVI uses a transmission format called "transmission minimized differential signaling" (TMDS). In the DVI standard, single-link means that there's one 165MHz TMDS transmitters connected, and dual-link means that there is 2 (doubling the bandwidth of the cable). So, a single-link cable can transmit 1920x1200 at 60 Hz, whereas a dual-link can transmit 2560 x 1600 at 60 Hz (about 1.8x the resolution).
So, a dual-link cable will allow you to use higher resolutions and frequencies (though common LCD panels are locked at 60 Hz) than a single-link one.
