    Abysmal design at its worst

    • Written by from Roslyn Heights

    Hooked up my computer to my 30" Dell display. The display works well on every other computer with a standard DVI port. I've tested this adapter on a MacBook, a MacBook Pro, and a Mac mini—all suffer from the same issue.

    With this new mini DisplayPort scam, it works only 90% of the time. Sure that sounds like it's pretty high, but we're not talking about an arithmetic exam; imagine life-support systems that only worked 90% of the time: it might as well not work at all!

    The adapter offers flaky performance, has been exchanged many times and no alleviation of the issue. Image gets distorted at random times, often when I'm doing something important.

    The adapter is bigger than my Mac laptop's charger; pathetic design. As I write this review, the image decided to distort again.

    Since is there no alternative product we are stuck with this piece of ____. Don't buy it unless you have to: you only need this if you have a 30" monitor that says you need dual-link.

    fail, bigtime

    • Written by from laurel

    When the computer wakes the monitor up out of sleep, it has about a 1 in 4 chance of having lost sync with the monitor. So I get two images superimposed, about an inch or two apart; impossible to use. This same monitor has worked flawlessly with my previous-generation MBP (which had direct DVI out) for almost two years, so it is either the new MBP or the adapter. I suspect the latter; I tried a lower-resolution "normal" mini displayPort to DVI adapter and had no problems at all ... other than the lack of resolution. Apple support seems surprised at the problem; odd, given the feedback on this page. I think I'm going to return the MBP and go back to the old one. Sigh.

    Minor problem: occasional flicker, but limited mostly to waking up.

    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.

    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.

    Really Apple?

    • Written by from Lakewood

    Being a web developer and graphic artist I use a ton of Apple products and for the most part I really love all of them. However, this adapter is the exception. First off, $100? Are you kidding me? The price of this adapter is one thing, unacceptable. I don't appreciate having to pay an extra $100 to hook up my MBP when the old one had a DVI connector built right into it. You could have at least given me 1 adapter for free with the laptop. And then there is the performance issue, always reconnecting my screen because it just shuts off or randomly displays static.

    This is very disappointing apple. Normally I hold you in such high regards, but this adapter is only one thing, that's a P.O.S.

    Periodically the display goes awry and I have to reconnect

    • Written by from Snohomish

    I am one of the many users who are experiencing what appears to be an interleaving issue of the DVI channels, from time to time the picture shifts and the image is unusable. I have to disconnect the adapter then reconnect it. I advise holding off purchase of this until Apple is able to resolve the problem.

    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.

    1st one sent to me was defective. Had a replacement sent. Also defective. Same problem as everyone else -- flickering, fuzzy screens. Used it on a Dell and an Apple Cinema Display. Same results.

    Wait till revision 2.0. This product is defective.

    No signal..

    • Written by from Espoo

    I ordered this from Apple Store in October and had to wait over 2 months.. After receiving this, I have now tried to get my HP LP3065 30" monitor to work... Macbook Pro doesn't even detect it!! This is so frustrating, I wanted to use Logic with 2560x1600 and now I can't. I need to contact Apple and ask a substitute.. Maybe I haven't waited enough? Maybe HP is not compatible with this? We'll see..

    Jitters on the letters

    • Written by from 京都市上京区

    This is a new product. I am not surprised that the bugs are not worked out. But I am disappointed that it does not work properly. I had no problems with my one year old macbook pro and the old dual link with my Dell 30 inch monitor. So why change what works? But apple did and I have the newest macbook pro. I waited a month to get this adaptor. And from the get go this product performs poorly. What happens is the letters all over your screen, from the top menus to the words in your screen seem to jitter or double up on top of each other. Letters become unreadable. And there is no predicting this. The first time I hooked up it went badly. I restarted and it worked. Now it seems to happen randomly. It does not matter which setting I use for the graphics card in the energy saver. Both go badly.
    A restart seems to fix it for a while. But at some point the problems rear their ugly head and you cannot read anything on your computer screen. You restart and hope you did not loose your train of thought at work.
    Do not buy this if you expect it to perform as it should. It does not. Use your older machine with a dual link port for performance and wait for Apple to make it right.

    Works for me

    • Written by from Layton

    I bought this a few months back, and I've found it to be reliable and free of defects. I use it for work to connect my 2009 13 inch macbook pro to my even older 30 inch cinema display. It works perfectly all day long, every day.

    Adapter works as long as updated model

    • Written by from Wichita

    This adapter works fine, I have a 30" Cinema Display running. I think most of the negative comments result from the earlier model which has an outdated bios version. If you do purchase from other source, make sure it is the latest model production. Wish adapter supported firewire is my only criticism.

    Avoid this adaptor

    • Written by from Brisbane

    This adaptor isn't working on either a 2009 13 in MBP or a 2011 13 in MBP connecting to a 27 inch 1440p screen. From both laptops, only flickering green static is displayed. Very disappointed. Not good enough, apple! For a AUD$119 adaptor, this is appalling.

    Bought this for my 30 inch Cinema Display and 2011 MBP and it works great at 2560x1600. I am also using a video switch for when I need to use my PC for gaming and I am very happy with it.

    New cable with Firmware 1.03 did the job!!!

    • Written by from Edgewood

    Followed the advice of entry: Aug, 2011 from MK Atlanta. I "Screen grabbed" (Cmd + Shift + 4) and printed MK's entry, and information about my Mac's hardware, which showed that I had a old 1.02 firmware cable. Took all the printed information and old cable to Apple store and they exchanged it, no problem. We weren't able to test it as the store was packed and everyone was using the monitors and laptops etc. But as soon as I got home, connected the new cable no problems, no snow, no flickering....Halleluiah!!! Why can't they post this, or send us an update? My new Subaru has had some computer updates since I bought it in February..... I get a letter, take it in, update, end of story. (note: I have a mid 2010 MacBook Pro)

    Worst Apple Product

    • Written by from Marietta

    It pains me to write this because I am a huge fan of Apple and own a ton of their products. This is the WORST product Apple has ever put out. It just doesn't work. I use it to connect a 30" Samsung 305T to my 15" MBP. Lots of flickering and noise, and that is when it isn't cutting out on me. It has been happening for YEARS with no fix in sight. Avoid at all costs!

    This product is junk -- is this a joke?

    • Written by from Austin

    I had to get this adapter when I went from my previous generation MacBook Pro 17" to a unibody 17" so that my Apple 30" display could display at native resolution (2560x1600).

    Sadly, whenever 1/3 or more of the display is dark to black, all kinds of horizontal interference lines randomly flash in those dark areas. If the screen is half or more black, this effect is unprofessional, highly distracting, and a constant reminder how much Apple really screwed this one up. It blows my mind how this product got out of QA and has been selling for well over a year now. Not only is this product unacceptably flawed, but so is the Apple department that oversees this product for letting it get though QA.

    I'm a hardware and software engineer (and an Apple developer to boot) so I think see what happened here. Apple built-in the display hardware (dual link DVI) in the previous MacBook Pro 17" (it did cost $3000, remember?), but they removed this support in the latest generation (likely to cut costs). The product is so flawed that I suspect there's something bigger going on behind the scenes for it to have made it past QA.

    I bought this to run my Dell 30" monitor from a brand new mac mini. I run the monitor at the full 2560x1600 resolution and need to plug the USB into an external power source through my iPhone charger. In short, the cable works perfectly about half of the time, and the other half of the time it is either:
    1) completely unusable, blurry across the entire screen or
    2) usable, but with flickering lines in the very dark areas of the screen.

    To fix the problem, I can either put the mini to sleep and immediately wake it, pull the USB cable from the charger, or restart snow leopard. It stops working sporadically in the middle of things and is VERY annoying.

    Apple please fix this!!! My previous macbook pro with a normal dual-link dvi connection worked perfectly and it is completely unacceptable to spend $100 on a adapter that doesn't work 100% of the time!
