    Working well with ACD 30"

    • Written by from Birmingham

    Recently replaced an ATI Radeon XT 1900 with an ATI Radeon 5770 in my Mac Pro 2,1. I was using 2 ACD 30" monitors so I needed this adapter for the second monitor since the 5770 has only one DVI port and 2 Mini Display ports. After 1 month, everything is working fine. No display issues.

    defective product, KNOWN ISSUE, demand replacement

    • Written by from San Francisco

    Hundreds of people, if not thousands, have suffered with this failure, perhaps Apple's worst product. If you look through discussions and the most helpful reviews, you will find hundreds of people with expensive 20+ and 30-inch monitors that will not function with this device and a new Mac. Do not buy this product.

    See Discussions Topic : Display flashes to solid black intermittently for solution

    As you can see from the post above, I believe I have a solution, jury-rigging an iPhone AC-to-usb charger with a USB extension to power the adapter. This brought back my 30-inch monitor. Also, the monitor works flawlessly with a 4 year-old Macbook Pro that has dual-link DVI native (no dongle/adapter).

    After spending an hour and half on hold, a senior tech admitted the KNONW ISSUE and is sending replacement now with firmware v1.02. I hope this resolves it, but others have said it is worse.

    Doesnt work

    • Written by from Santana de Parnaiba

    Just doesn't work, unusable. I have an early 2010 iMac and a Dell U2711 and it is totally useless. The screen keeps going to sleep for no reasen, keeps loosing signal and often the image becomes all noisy and unrecognizable.

    MacBookPro and Dell U3011

    • Written by from Aptos

    This dual link adapter did not provide the 2560 x 1600 resolution capable on the Dell U3011. My MBP is a mid-2008 with Nvidia graphics card 9400M and 9600GT. Using the minidisplay port to HDMI I could achieve 1920 and using the minidisplay port to VGA I could achieve even higher resolution, but still short of about 400x550 -- ish.

    I am going to return this product. And try the minidisplay port to display port cord. Otherwise, I'll be sticking with the VGA adapter.

    I HAD NO CHOICE

    • Written by from Houston

    I have been using my 30" ACD for over a year now with my 2 year old Macbook Pro. It had the DVI port so I was able to connect the monitor directly. I decided it was time to upgrade and I bought a new i7 17" Macbook Pro. Guess what? No DVI port. So I had to buy the Dual-Link DVI Adapter. They should have never taken the DVI port off of the Macbook Pro. So here I am stuck with either a double image (like that you see when looking at 3D without the glasses on) or blue/green/red interference lines.

    So I took the Macbook Pro, monitor and cable to the genius bar. Some genius. After trying 3 cables I was told that there was nothing he could do and that I should sell my monitor. THERE IS NOTHING WRONG WITH THE MONITOR!!!!!!! He told me I was taking up too much of his time as he was only allotted 15 minutes to work out the problems. He let me pick the best Adapter and sent me on my way.

    NOW WHAT??????

    I am calling Apple tomorrow . . . . .

    Until the next post :(

    Pricey but does the job fine

    • Written by from Chicago

    It is pricey, and honestly it is one of the things that help me off from buying a new macbook pro. Unlike some of the people here that have had issues though, I am using this with a new 15" macbook pro i7 and a Dell 3007WFP-HC 30" monitor for the last week and have not had any issues. No flickering, needing to restart, etc. I am also not a fan of this taking up another usb port, but if you use a good powered usb hub, it isn't really an issue. i don't see many alternatives for this and it works fine for me.

    Works just fine ...

    • Written by from WYCKOFF

    I'm not sure why others have panned this product. I bought a 30" Cinema Display to use with my Mac Mini and obviously needed the Dual-Link adapter for maximum resolution. Well, it works just fine. No problems. Gorgeous screen images every time.

    Works fine but so pricey

    • Written by from Binningen

    Seems to work without any issues so far described by others. I am just very surprised that my adapter has firmware 1.01 even though this seems very old and supposed to not work. Hence only three stars as it is very expensive and with outdated firmware.

    Flickering Horizontal Lines

    • Written by from La Habra

    Computer is a new i7 iMac, secondary display is a 30" Cinema Display. In black areas of the screen, there are horizonal lines flickering across the screen. It's usable, but ugly.

    Apple won't send a replacement until they receive this defective one, which will leave me out of commission for a week or two. I stopped by an Authorized Apple Retailer, and got another DisplayPort adapter. The replacement was WORSE than the original.

    The most un-Apple product from Apple ever

    • Written by from San Jose

    I pretty much buy everything Apple makes and love it. However, this adapter is junk by any standard. I hooked it up to two different Dell monitors and in each case the screen will randomly flicker or go fuzzy. I usually spend 15 min of my day just unplugging and plugging in the display to get rid of the fuzz. Apple, I still love you, but please right this wrong and fix this product.

    Works well with MacBook Pro, but surprised me a bit.

    • Written by from Folsom

    Because I work with both Mac and PC, needed to hook-up a Dell RazorSharp U2711 Monitor to my MacBook Pro. Found out *after* I bought the monitor that I needed this adaptor if I wanted to access the monitor's full 2560x1440 resolution (that was after the AppleCare rep told me I needed to upgrade my RAM from 4GB to 8GB, which I questioned and he found out to be wrong). I bought and hooked up the adaptor, but was surprised to find out that I was *required* to also hook up the USB plug, as this apparently provides the extra power to handle the dual-link hi-res display. Without the USB plugged in, no go. Also, needed to change out a Single-Link DVI-D cable to a Dual-Link DVI-D (didn't work without it). It now works fine, but I sure would prefer an Apple LCD Display. The Cinema Display's lack of ports and exclusive use of the MiniDisplay Port cable prevents me from hooking it up to a PC via a reasonably-priced KVM switch.

    Replace Dual Link DVI Adapter

    • Written by from San Diego

    This has been driving me crazy for months.... I had streaks going across my 30'. I tried everything except replacing....

    It took a trip to the APple store and demanding a replacement.... they tried to say that this was not an issue with the cable but i just demanded an exchange after reading this thread.

    Replaced cable drives my 15' macbook pro with 30 monitor perfectly.

    Doesn't work!

    Plugged it in to my MacBook Pro with my 30" Cinema Display, worked once only with flickering results. Apple doesn't seem to be interested in resolving this faulty issue with this product. Very sad.

    Works enough.

    • Written by from Herriman

    Connected successfully to my third party monitor (Samsung SyncMaster 220WM). Although, when display wakes up from its "sleep" the resolution is all wrong and cannot be changed; computer must be restarted to use correct resolution. Apple support could not help me resolve this issue so I disabled my sleep settings.

    If I don't let my displays sleep there is no problem. I prefer this solution (because of performance and price) to my easily breaking, Matrox multi-screen device.

    Works like a charm

    • Written by from chicago

    Using this product I connected a circa 2008 30" HD Cinema Display to a brand new 27" iMac quad core with Intel I7 processor and ATI HD Raedon 5750. The 'install' took about 90 seconds, and it worked perfectly from the get go. I suspect those reporting of flickering or diminished quality are running on insufficient processsors and/or video cards.

    Like a lot of people, I too am experiencing green & blue flickers on black/dark parts of the screen when connecting my brand new 15" MBP to an Apple 30" Display. I had hoped this wouldn't happen to me with brand new equipment but there you are...

    Expensive & Made my 30" Cinema Display unstable

    • Written by from NORTH HAVEN

    For the price I would expect good quality, but no. The screen flickers and render my cinema display unusable when the 30: display is already very unreliable.

    I just have to deal with the flickering forever.

    no troubles here -- "It just works"

    • Written by from Logan

    Connecting 13" MBP (2009, OS 10.5.8) to 30" HD Cinema Display. Plugged it in and it works.

    I do notice occasional flashing lines on a black background (on the cinema display only), but that's it. I'm very pleased. I had no idea I'd be able to drive a monitor of this size with my MBP.

    Sweet!
