    Works, but flickers and dies unexpectedly

    • Written by from LaGrange

    I read all the bad reviews, but had to buy the adapter anyway -- when I upgraded from my old MacBook Pro to the new MBP with mini displayport, this adapter was the only way to get my 30" Dell monitor to work.

    I never had any problems plugging the DVI directly into my old MBP, the monitor was crystal clear and never had a single issue. Since using the adapter, there is a constant flicker of red, green and blue pixels that are hard to notice, but if you're looking at a very dark screen they're very apparent.

    The adapter will also just die at random times, displaying a distorted picture, vertical lines, or both. I'll have to completely disconnect and reconnect to get it running again.

    For $100, you'd think it would be made better. Very disappointing especially since it's the only way to get my MBP to work with my monitor.

    New Macbook Pro and Display Connectors

    • Written by from Tempe

    I just bought a new Macbook Pro with the i7 chip. It's a screamer and works beautifully in almost every respect but the display connectors. My old Macbook Pro had a full size DVI connector that directly supported every display mode I needed out of the box. Now to support my 30" Apple Cinema display I need this clunky connector? Really? To top it all, I bought the mini display port to DVI only to discover it's DVI-D (single link) not DVI-I. Every VGA to DVI adapter in my school is DVI-I so I can't connect without another adapter! So in the end I'm going to have to buy 3 connectors: mini displayport to dual-link DVI, mini displayport to DVI and mini displayport to VGA. A total of $160. For a company that has a reputation of attention to detail, Apple failed on this one.

    It's a driver issue

    • Written by from HILLSBORO

    I got this for my Samsung 305T. Although it displayed properly, the screen would continue to flash. It was never showing the screen for more than a few secondss before it would flash dark again. Totally unusable. I tried connecting the USB to a more powerful source but that didn't help.

    I measured the current drawn from the device from the USB port and it never drew more than 200 mA, which should be fine for most computers with USB ports. I don't see how that could be the issue.

    I partioned my mini mac for Windows XP and lo and behold. There are absolutely no issues when running the cable and monitor using XP on the same mini mac. This rules out the problem being the monitor, cable or mini mac. The problem is the Apple driver, either for the adapter or for the integrated video. Since it works on XP, I'll keep the cable. But I can see why there are so many complaints!

    Sometimes works

    • Written by from Sandy

    Expensive piece of hardware, but is amazingly flaky. I mean it works most of the time, but is subject to random problems is the form of messed up displays (get used to unplugging and plugging back in). It's a digital to digital converter but it produces artifacts that you would expect from a analog to digital converter.

    Seriously, can this not be done better?

    (yes I have the latest firmware)

    Flaky at best

    • Written by from Peekskill

    I was so excited to get my new 17" MacBook Pro until I realized that this "Pro" product didn't work with my 30" Cinema Display anymore without me dropping another $100. I then get the adaptor to find that it is really flaky, my screen flickers few times an hour and it just seems like the whole thing was an afterthought at best. Really, really disappointed that Apple did this to their core audience who spends the most money on their products.

    Found solution for Mac Pro 4,1

    • Written by from Las Vegas

    I just bought this adapter to run two 30" Apple displays on a 2009 Mac Pro with GT120 video. At first I could get nothing from the mini display port using this adapter. But from reading the other comments regarding usb power, I tried connecting both the usb connector from the adapter and the usb connector from the display directly to the back of the Mac Pro (rather than connecting the display usb cable to the adapter case). That brought both displays to life in full resolution. Only been running a few minutes but seems good. Agree this is a very disappointing product, and as a very big purchaser going all the way back to Lisa (1983) I expect better of Apple.

    How to run with Dell 30"

    • Written by from Dothan

    The is a comment from a gentleman in this thread that mentions the USB connection. That is the key. I have a 3 year old Dell 30" monitor that would not work with the adapter. I have noticed that none of these laptops have enough juice to power the USB devices on a chain of hard drives, etc. So I had purchased an AC adapter powered Tripplite USB hub. When I plug the USB cable from the Apple dual link adapter to the powered hub the adapter works fine so far.

    Summary: If you want it to work you need an AC adapter powered USB hub or similar device.

    Vertical stripes and pixelated screen upon waking from MacMini 2.53

    • Written by from Bellevue

    I should have read the reviews here first, as I too am experiencing vertical banding upon waking up my 30" cinema display from sleep (usually overnight sleep only). I just purchased a new MacMini 2.53 (server model). I have not yet attempted to plug the USB adaptor into a powered USB Hub, as other have suggested. But this cable cost $100, and it should work plugged into the MacMini, unassisted.

    I was tempted to purchase the new 27" iMac, but I did not want to part with my 30" matte screen. It has to be the cable, as my 30" cinema display never exhibited this issue plugged into my MacPro (2 year old model). The cable is the only variable here.

    Dual-Link DVI Adapter with Nov 2009 iMac and NEC MultiSync 3090WQXi

    • Written by from Alcoa

    The Apple Mini DisplayPort to Dual-Link DVI Adapter rates 5 stars for driving the NEC MultiSync LCD3090WQXi 30" monitor at 2560 by 1600 pixel resolution from my Late 2009 iMac. The problem is that I cannot calibrate the monitor color using NEC's SpectraView II software and the Mini DisplayPort to Dual-Link DVI Adapter. It appears that the Mini DisplayPort to Dual-Link DVI Adapter hardware and/or OS X software drivers do not provide for proper communication between the SpectraView calibration software and the display's internal processor. I have to remove the Dual-Link Adapter, install the Mini DisplayPort to DVI Adapter (Single-Link), and calibrate the monitor at a 1600 by 1200 pixel resolution. I then have to reinstall the Dual-Link DVI Adapter to get the 2560 by 1600 pixel resolution.

    Not the quality I'm used to from Apple.

    • Written by from Laval

    I'm a Mac fanboy and I promote Apple and it's quality products wherever I go and also write software for the Mac. Unfortunately I have to write a bad review for this one.

    My setup is Macbook 5,1 Unibody with a 30" Dell 3008WFP Monitor.
    mini-DVI to DualLink DVI cable with firmware 1.02.

    At first I thought it was my screen that was defective so I got an exchange from dell, since then I've exchanged this cable for the third time and still the quality is not what I am used to from Apple.

    The new cable works fine at maximum resolution for a couple of days but then I start seeing pixelation ( like snow on a old TV set without cable) in the bottom half of the screen soon followed by the whole screen becoming green and flashing back to normal colours at a rapid 60Hz. My guess is that this adaptor cable looses sync after a while.

    If I disconnect the screen itself from the adaptor and reconnect it, nothing changes the adaptor still flickers the screen image, but if I disconnect the adaptor from the mac book and reconnect it, the adaptor is good to go for a couple of hours before it starts behaving badly again.

    I've tested my screen on another computer and also tested the screen with a normal mini-DVI to DVI Cable, both situations worked flawlessly.

    Basically said, this adaptor is not stable at all.

    Intermittent horizontal lines, snow, noise on black...

    • Written by from San Francisco

    ... just like so many others are experiencing.

    Other issue is that waking up the MacBook 17" from sleep will result in the 30 inch Cinema Display to wake up first, causing that monitor to be the default controller/finder monitor (#1).

    Firmware version 1.02 fixes the problem

    • Written by from Beaverton

    I bought this adapter 4 months ago for my MacBook aluminum (bought Jan 2009) and Dell 3007WFPHC 30" LCD. The adapter had firmware version 1.01 and had the same issues many users reported: intermittent flickering, color speckle noise, blurry text, and analog-like color "snow". I could fix issue temporarily by putting the display to sleep and waking it back up.

    Today I took the adapter back to an Apple retail store, where a manager gave me a new replacement that has firmware 1.02. The new unit has performed flawlessly over the past several hours. If you have problems and have firmware 1.01, see if a retail Apple Store will also give you a free replacement.

    Fyi, find your adapter's firmware version:
    Finder -> About This Mac... More Info... Hardware -> Graphics/Displays -> look for "Adapter Firmware Version: 1.xx"

    Rating: Start with 5 stars because firmware 1.02 works, minus one star because the adapter costs too much, then minus two more stars because Apple released the product without adequate testing, wasting hours of my time trying to get it to work and eventually driving around town to get a replacement. 5 - 1 - 2 equals 2 stars.

    Bad Apple...

    • Written by from Lewes

    MBP + 30 inch ACD. As a Mac user for over 20 years this is the worst Apple product I've used. The picture quality generally is okay but on black I get horizontal flickering, which is simply unacceptable. As someone else remarked, I wouldn't mind paying the $99 if it worked but this is way below Apple's usual standards. Shameful.

    Flickering problems!

    • Written by from Belmar

    I bought this adapter so I could plug my new unibody, 17-inch MacBook Pro to my 30-inch Cinema Display. The problem is that my monitor flickers unpredictably during use. I've had this Cinema Display for over a year, and it was hooked up to two other MacBook Pros. This problem only occurred after this adapter was used to hook up to my computer.

    Works most of the time.

    • Written by from Tucson

    Apple 30" Cinema Display, Macbook 13" unibody 2.4Ghz, 4GB mem

    I experience flickers (so far only right after the computer starts up), inserted DVD, DVD player automatically opened and full-screen, just got black screen, everything besides the mouse cursor became unresponsive. Had to power-off via holding power button.

    Its just doesn't seem stable, but what choice do I have if I only have a MB and want to use my 30" display (used to have a PowerMac G5, but sold it)

    Hopefully this is something Apple could address in the future with a software/driver update.

    $99 to use my $1600 laptop with my $1800 display. A complete rip off. I might possibly have been able to overlook the $99 if it worked perfectly without problems, but that is certainly not the situation here.

    DisplayPort Adapter (or Nvidia driver) Freezes/hangs macbook or causes snow

    • Written by from Chatsworth

    I, like many here, am having problems where one of these behaviors occur when I connect the DisplayPort adapter:
    - There's snow on my external display (Samsung SyncMaster242MP)
    - The external display blinks on then off.
    - After returning from display sleep, the monitor continues to display nothing (black).
    - The MacBook hangs when removing the adapter and then plugging it back in. But not every time I do this. And I'm usually doing this to get the MacBook to re-detect the display due to one of the aforementioned issues.

    There was mention of an Apple update to the MacBook Pro Nvidia drivers that occurred in late January. That update has since been removed by Apple from their support site.

    I'm giving the adapter a two star rating because it does work, for as long as I keep the MBP from not sleeping the display, once I convince the MBP that there is a display attached and it syncs up without snow.

    Soooo...I'm anxiously awaiting news from Apple in some form (support KB, new driver, new adapter, anything!).

    Apple changes product description

    • Written by from Toronto

    This product description use to state this adapter would work for any monitor that required a dual-link dvi connection.

    After receiving multiple complaints, Apple has changed the description to include only their 30" cinema display instead of fixing the real issue.

    The adapter WILL work with my 30" Dell display, but I occasionally will experience issues (static, snow, etc) - only a reset (computer, display, settings, sleep) will bring it back. A serious nuisance.

    Working fine after 3 days...

    • Written by from Toronto

    I have no doubt there are significant issues with some or most of these adapters, but unfortunately it is the only way to hook a new MacBook / MacBook Pro up to a 30" monitor; anyone who has such a display is unlikely to give it up.

    I bought one of these from the local Apple store, and tested it in the store with a Macbook Air + a 30" cinema display they had there - worked fine. After 3 days of 8+ hr/day use with a MacBookPro purchased in Early Jan connected to a Dell 3008WFP it is just fine - display rock steady, no issues whatsoever. The MacBook is plugged in (powered), one of the MacBook's 2 USB ports powers the adapter, the other goes to the USB hub located in the monitor. Energy saver is set to "better battery life" (ie 9400M); haven't bothered to enable the 9600.

    Yes, this is far too expensive, large, and generally a ridiculous solution - particularly compared with the direct-connect dual-link DVI on the previous generation. And yes, why is there not a mini-DisplayPort to DisplayPort cable available, 4+ months after the product introduction? However, the particular unit I appear to have works just fine. If you really need one of these things, perhaps you can get lucky and wind up with an operational unit as well.

    Otherwise, sticking with a previous-generation MacBook with a more immediately useful display connector, or perhaps a different brand of laptop all together would serve as a better solution.

    It works, but...

    • Written by from Oakland

    I have it attached to my 30" Apple Cinema HD display. I don't get any flicker and the screen always comes up, but any areas of the screen that are completely black display a rapid faint flicker of horizontal lines (think film noise). It's subtle but definitely noticeable.

    I'm on the fence about returning it.

    You're joking me? $100 for an adapter for a perfectly good working and relevant 30" ACD monitor??!

    Not to mention i cant use the firewire on the back of the ACD. and it barely works most of the time which is just the kicker.

    I mean, its not that hard to create something that looks simple and elegant, but put some craftsmanship and quality into it really!

    You have access to a multitude of Apple products in your factory, do a bit more grindstone testing before we pay the burden of failed products that dont get the quality assurance customers that are willing to pay for apples premium.

    Good luck next time.

    (dont get me wrong im not here to bash Apple at all, I'm just reluctant with all these quiet changes and no realization that customers are offered standards and are now being kicked high to adapt or get nothing)
