    Ruined My Experience

    • Written by from Piscataway

    I was looking for a new computer to drive my 30 inch Dell Monitor, and I decided to make the switch from PC to Apple -- but after dealing with this cable, I'm going back to PC.

    After hooking up this adapter I experienced sporadic issues with screen flickering, blurriness, and white lines. I've tried several work-a-rounds to eliminate the problems but none of them work.

    Don't buy a new Macbook if you want to run it on a monitor that requires dual link DVI, you will be disappointed.

    Stability issues

    • Written by from Seattle

    I've been having some of the same issues with this adapter. It works (mostly) fine with my Dell 2009W, but it has weird issues and cuts out occasionally. Also, it doesn't have DVI-I and so my other DVI adapters don't work with it.

    Agreed: worst Apple product ever.

    • Written by from Tucson

    I really hope this is a software problem with the NVidia chip and not a problem with this adapter... but the flickering is ridiculous! They say it's not compatible with non-Apple monitors and say that's the reason for many users' problems (complete nonsense...) but that doesn't explain the identical problems I have with my NEW Apple 30" that worked perfectly with my old MBP 17".

    There had better be a fix soon because this is ridiculous.

    worst Apple product ever

    • Written by from Dublin

    I've been happily using my 30" Dell monitor with previous MacBook Pro (which had dual-link dvi output), when I upgraded my notebook I purchased this adapter, hoping that it will work fine too. Unfortunately, it didn't! Simply put, this adapter is very unstable. I'm always using with power adaptor is connected, with "High Performance" graphics mode. Couple days it worked fine for couple hours, but usually it goes crazy after 10-15 minutes usage; seems like having a refresh/synch problem. Some times unplugging and plugging it back solves the problem for another 10-15 minutes... This is really frustrating....

    At least it doesn't catch fire

    • Written by from Powell

    Unfortunately I ignored all the reviews and gave apple the benefit of the doubt. I get the distorted unreadable picture about 20-25 times a day and have to press option > command > eject to put the display to sleep. When I wake it up, it is fine again.

    I will probably retire my new macbook and fire up the old and rusty but trusty HP desktop. It's faster anyway.

    Do buy this product until Apple can recognize (let alone fix) the issue.

    Causes pixel snow with new Unibody MBPro and 30" Apple Cinema Display

    • Written by from New York

    I just bought a new 2.66Ghz 17" Unibody MBPro 2 days ago and hooked it up to my 30" Apple Cinema Display with the Dual-Link DVI adapter. At first, it worked fine and I thought I got lucky, but after the first waking from sleep, I started getting the flickering pixel snow in the background. Now, after 2 days, it's gotten worse--and it's really distracting while I work.

    I've tried unplugging/replugging the adapter, tried both graphics cards settings, detached all USB peripherals from the 30", but it doesn't solve the problem. I don't know if it's even worth exchanging the adapter or MBPro given how persistent these problems seem to be based on what I've read here and in various forums. I'm hoping there's a software fix in the works and it's not a hardware issue. I love Apple products and have been a customer for 15 years, but this is extremely frustrating.

    I am using all Apple products... brand new 17 inch Macbook Pro and Apple 30 inch cinema display. I get random linear, static like flickers across the screen that predominately affect the darker areas. For those of you saying you don't have problems, try putting a large jet black area on your 30 inch monitor before clicking up the star rating on this defective product.

    Mac Mini(2009) Problems w/Adapter

    • Written by from Fremont

    Just to chime in with the rest of the crowd, I'm also experiencing flickering issues with this adapter. I have a new Mac Mini w/Nvidia graphics that powers the 30" Cinema perfectly, no graininess or distortion, except for that irritating screen flickering every 15-40 minutes. I thought the Mini had issues, I'd never suspect it was the adapter until coming to this forum. Hope Apple fixes this problem soon considering that the adapter was 1/6th the price of the Mini.

    I thought I would be one of the lucky ones after waiting 3 months for my adapter.... I guess not. I have slight flickering and my wired mouse tends to be very jumpy. Honestly, if I would have known this beforehand, I would not have bought the new MBP.

    • Written by from Newark

    I read the reviews, but since I replaced my 2 year old macbook pro 17, with a brand new unibody, i needed this adapter. Tried 2, absolute terrible performance. Display looks grainy, it flickers every now and then, fet random bars down right habd side, and I cant see to use the usb socket on the adapter even with an iPhone - please leave well alone until its fixed.

    Slow MacBook Pro

    • Written by from Davis

    After paying $99 plus tax, I thought I will be very happy driving 30 inch Apple Cinema Display from my new MacBookPro. Wrong! It is SLOW !!! Especially when I run VMWare Fusion full screen mode, my Mac runs so slowly that I fall asleep. I am not sure why they made MDP to run only half the capacity. Apple must have known this, so then they should have left dual DVI or provided a different solution.

    Problem's with 30" Display

    • Written by from Greenwood

    As others have stated there are many problems with this adapter and using it with a 30" display. I never had a single problem with my two prior 15" MacBook Pro's and my Dell 30" display. With this adapter I experience flicker every 10-15 minutes and have seen it drop one link of the dual-link connection as well. I would avoid this adapter and had I known this would not have purchased a new 15" MacBook Pro.

    Apple 30 inch Cinema Display Flickers

    • Written by from MIAMI

    I did not need this adapter with my late 2007 Model MBP using the internal DVI connection. However, living on the bleeding edge, I had to get the new MBP back on Dec 31, 2008. I since learned the hard way that I needed this new Mini-Port to Dual-Link DVI Adapter to match the resolution of my previous MBP. Then I got an unexpected


    This thing flickers under all circumstances. It doesn't matter if I just turned the MBP on, or after hours of use. I have been trying workarounds that others have tried and have been sifting through rumors of hardware issues, software issues, or environmental causes to the problem.

    I am not one the usually writes reviews on products, but I simply could not let this one slide. I too read the reviews prior to purchasing this product, and I did not see one mention at the time to this particular issue at the time. Now I see that others are experiencing the same problem. I encourage everyone that has purchased this product, and experiencing these issues to voice there feedback. I would tell others to hold off on purchasing this product.

    More importantly if you use an external display and are considering a new MBP I would hold off until there is official word from Apple that the issues have been identified and resolved with either this product or more seriously a new generation of MBP.

    Does not work with 30" Dell and MBP

    • Written by from Minneapolis

    We use 30" Dells and Macbook Pros at work, and between two machines and monitors, we're determined this product is terrible. I've tried working with the lid closed, re-plugging from the monitor end, the laptop end, tried the "official fix" from Apple including deleting plist files and resetting PRAM, and still see the sudden loss of clarity/fuzziness/noise issues I've seen that other have photographed. My hope is that Apple will replace this cable with one that works, my fear is that no cable will work and no 3rd party cables will be available.

    Disappointed by this poor product

    • Written by from Los Angeles

    As everyone else has mentioned, this product (as currently integrated with OS X) is defective.

    Apple delayed the release of this product, charged an outrageous price, and then did not provide the necessary software updates to make the product work.

    I have new MacBook Pro 2.53 with a 30 inch Apple Cinema Display.

    My mouse jumps several inches sporadically. I've seen in forums online that there is an easy way to replicate this problem. Drag the mouse in a circle over and over. Every few times, the mouse will jump several inches.

    In addition, the screen flickers, changes colors, etc.

    I'm confident that this is just a software problem. (I hope so). Apple MUST update this product, software, or refund the customers. At the moment, we bought a dud.

    Design Engineering Staff Shouid be Publicaly FLOGGED!!

    • Written by from San Diego

    Please forgive my possibly ignorant rant knowing I am open to any schooling from an informed source, unless otherwise corrected I believe the Design Engineering Staff at Apple should be publicly Flogged or at the very least be made to give up a portion of their paychecks to accommodate the prolific permutations of video connectors Apple has SPAWNED! Really now, Intel / PC based computers, that offer equivalent graphic performance have managed to utilize the same 15 Pin cable for 20 years!!! Could someone please tell me WHY APPLES FEELS IT IS COMPULSORY EVERY TIME A MODEL OR MID MODEL CHANGE HAPPENS THEY MUST INVENT ANOTHER *&!@#!# VIDEO CONNECTOR?!!!! One must carry a printed product compatibility map the size of a bed sheet to PURCHASE the correct $30 to $125 adapter so that one can connect AN APPLE MONITOR TO AN APPLE COMPUTER!!! Shame on Apple once again for showing absolutely NO ALLEGIANCE to Long Standing Consumers! I had hoped Intel would have put a stop to the 8Pin, D-Sub, BNC, 15 Pin, Powerbook 100 Series adapter, Powerbook Duo Adapter, DVI, VGA, Mini DisplayPort to VGA, Mini DVI to VGA, Mini DisplayPort to DVI, Mini DVI to DVI, Mini DVI to Video, Mini DisplayPort to VGA, Micro DVi to Video, MADNESS!!! Just to name a few.....

    Monitor flickers every 20-40 minutes.

    • Written by from Richboro

    Our office has 9 of the new MBP laptops that require these adapters to drive our 30" monitors. I personally have a 30" apple display, all others are 30" Samsungs. Every monitor regardless of brand or age flickers (blanks out and then comes back on) every 20-40 minutes. None of the monitors exhibit this behavior when using a direct DVI connection to an older MBP. Problem is either this adapter or the graphics chips in the new MBP's.

    Joining the crew on the ship of fools

    • Written by from Bloomington

    Nothing extraordinary to report. I'm making a mark in the vain hope that the sheer number of lemmings that are taking one for the Apple Team will somehow see redemption with Apple coming clean on this, and resolving the Mini DisplayPort issues. I hope it's the adapter, and not the Laptop hardware. I've got a 15" Unibody, full CPU & RAM, and a TripleHead2Go setup. It runs absolutely fine off my older MBP, and can't wake from sleep on the new one without serious scanlines, artifacting, and confusion. I've wasted 8 hours jacking around with this - who can I bill for that?

    Poor performance

    • Written by from TAMPA

    After waiting 2+ months for this product to come out, then paying the $99 for what amounts to a cable adapter, I find the performance to be poor. At "millions" of colors (set in Apple Display Prefs), I get a constant flicker. At "thounsands" the flicker is manageable at 1/hour or so.

    Apple SHOULD do something to recall/fix this adapter.

    Wait for them to fix the bugs before buying

    • Written by from Edinburgh

    If you want to use a new MBP with a 30 inch cinema display, you have to buy one of these. But there are a lot of bugs still to be fixed, such as:

    - scrambled video after wake from sleep
    - stuttering playback in Front Row
    - jumpy cursor movement
    - momentary video blackouts

    My advice: don't but this (or a new MBP) until the problems are fixed. Check the forums for the latest reports...

    The device is also cumbersome and ugly, doesn't have a firewire-thru port and is rather expensive. That might be OK .... if it worked properly.
