    confirming flicker problem

    • Written by from Nicholls

    Most people who buy this overpriced thing complain of similar problems - it flickers every now and again (completely randomly) for half a second to a second. I contacted mac support and they got me to delete two specific files (forget what they were now) but that did nothing anyway. I want to exchange it but from what I've read over the net I'm almost certain the replacement unit will ave the exact same problem! its completely ridiculous that this malfunctioning product is the only way to attach a high-res screen to the macs.

    Dismal - Was hoping the reviews were wrong but they're not...

    • Written by from Santa Clara

    I have the unibody 15" and the Dell 30" LCD display, had to wait 3 months to get the adaptor to make them work, and now I got it I am having the same nightmares as everyone with the flickering, screen blur, and the worst, complete static on-screen. DO NOT BUY if any of that is a concern. I say the product works as advertised 20% of the time.

    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.

    broken 125 dollar cable...

    • Written by from PARIS

    I bought mine at the Tokyo Apple store (Ginza) on the 11th of january 09, betting a first faulty batch would have been swiftly corrected.

    Wong. Not only does it cost 125 USD (my god, have they lost touch with reality?) (and why is it so huge ?) but it also flat out does not work. Every hour or so, I have to unplug the USB cable, and replug it, after the screen gets it all wrong.

    I can't be mad at Apple, as the Macbook Pro I bought it for is an incredible piece of hardware, a pure jewel, but this cable thing is just plain ridiculous.

    I really hope Apple comes up with a satisfactory solution, and one that does not cost a dime.

    APPLE please fix this defective product- it's an embarrassment to Apple!

    • Written by from Lexington

    I bought two of these (one for home and one for the office). The office unit drives a Apple 30" cinema display. The home unit drive a 30" Dell monitor. The computer in both cases is a new, current-generation (as of May 2009) 17" MacBook Pro.

    Like everyone in the world, I have experienced the same unacceptable problems. On the Apple: all black or dark-colored areas of the screen have rapidly changing horizontal lines of noise. Changing graphics preferences from normal to high performance does not fix the problem. Sleeping and waking the computer does not fix the problem. Changing or replugging the mini DVI or its USB cable does not fix the problem. Giving up on Apple and getting a PC would probably fix the problem.

    On the Dell, the same problems exist plus the interlace problem in which every other line is shifted, making it impossible to even read text.

    I even swapped the home and office units and I get the same results as detailed above. Apple-- it's an embarrassment to the company that you continue to sell this product (and at $100 a pop!) and have not acknowledged the problem officially. Please issue a fix or replacement program-- your loyal customers deserve better.

    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.

    Incompatibility Issues

    • Written by from Leonardtown

    I think the theory of this product is sound and I really hope Apple releases either some support documentation or graphics driver updates to help it perform better. My experience is that when connected to a 30" HP LP3065 2560x1600 monitor I can only get the macbook to put anything on the monitor when it is "mirrored" off the laptop screen and even then only at 1280x800. With my other Panasonic Pro TH-50PFD9UK 1920x1080p compatible plasma display I was able to get it to output video in what appeared to be 1920x1080, but again I believe this was only in "mirrored" mode. Personally, I think it is some sort of obnoxious joke that Apple shipped this product with no documentation and no tech support website.... sure, the Apple user experience is just so magically awesome that it will just telepathically "know" what I want it to do when I plug it in... either that or I am supposed to be magically aware of all of the configurations and software settings it needs as soon as the breathe the air from the open box. Just ridiculous! But I have high hopes.. so please get us a software driver update that robustly supports this product, it has huge potential!

    Doesn't work with my HP LP3065

    • Written by from Sunnyvale

    New MacBook Retina and this display adapter don't work for my HP LP3065. The MacBook never see the display. The display works fine plugged into the same DL DVI cable plugged into a Mac Pro so it isn't the monitor or the DVI cable. The MBP or the adapter are the issue,

    Works Perfectly! Awesome Display on my 30" HP LP3065

    • Written by from Brooklyn

    This Dual-Link DVI adapter works perfectly -- provided you supply it with adequate power (1A) via the usb plug on this adapter's cable. To ensure adequate power, you are seriously encouraged to buy the Apple USB Power Adapter ($29) with this (it should really be included in the box with this adapter :-( ). Yes, it is an additional $29, but you won't be disappointed with the results!

    The other reviewers had bad experiences because their Macs did not supply enough power to this adapter via their native/built-in USB ports. Bypass those issues and buy the correct power adapter and enjoy Dual-Link DVI excellence at 2560x1600!

    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.

    Very poor display quality

    • Written by from Mountain View

    I tried to use this to connect a Mac Mini to a 30" monitor. There was a lot of flicker. Also, quite weird was that there were horizontal "ghost lines "projecting outwards from the edge of the windows.

    A rather poor performing product, especially given the price!

    Works wonderfully - IF it's got firmware version 1.02

    • Written by from Ferndale

    I bought this product yesterday and was disappointed that it caused a lot of red/green video noise with a 30" Apple display. It was the same with 2 different MacBook Pros (both unibody - one Core i7, one Core 2 Duo) and System Profiler showed that this brand new adapter came with obsolete firmware version 1.01 installed.

    After trying several suggestions in the Apple discussion forums, including rerouting video cables away from sources of electrical noise, using a separate USB "wall wart" power supply, and even wrapping the video adapter with aluminum foil to shield it from noise, I gave up and returned it to the other local Apple store (it's closer to my house) where it was cheerfully exchanged.

    From the packaging, it's impossible to tell which firmware version is on the hardware inside the box. Though the store manager was a bit reluctant to let me open the adapter to check the firmware version in-store, he said I could exchange it again if there was any problem.

    Fortunately, with the new adapter the video quality was immediately better. There were no green and red dots dancing all over my screen and firmware version 1.02 showed in System Profiler.

    Steve Jobs, if you read these reviews, it would be helpful if you had one of your Quality Managers work to get all of the old stock out of your stores. As an Apple shareholder I am concerned at the number of problems people are having with this device. One of the highest ranking reviews online calls this "The Worst Apple Product Ever?" and the store manager who helped me with my return could only say "wow!" when he searched for a way to update the firmware.

    This is a good product that would be great if it didn't come with "known buggy" firmware installed. At theminimum there should be a way to update the firmware, but neither Software Update nor a search of the Apple Support Forums / Knowledge Base yielded any results.

    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.

    Not with a Macbook Pro Retina

    • Written by from Saint Petersburg

    I bought this to use with my Macbook Pro Retina laptop and found that it only provides DVI-D Single Link - not Dual Link - output. My 30" Dell 3007WFP display requires DVI-D Dual Link in order to display its native 2560x1600 resolution. With this adapter, I can only use the display at a resolution of 1280x800. Others have reported getting Dual Link output from systems like the Macbook Air, so it seems like the problem is with the MBP Retina, not necessarily with this product.

    Do Not Buy

    • Written by from Duncanville

    I own the Macbook Pro 17" unibody and a Cinema 30 display. I am running the latest firmware and Snow Leopard. I still get some distortion (e.g. sparklies) using this product. My only advice is to not buy this product. Honestly, this is the worst Apple product I have ever bought. I am happy with the rest.

    Fundamentally Flawed Product

    • Written by from Sunnyvale

    I'd actually give it zero stars since the product fails at the one thing it's supposed to do -- the short is that all current macs, except for the mac pro, do not really support DVI based 30" displays, and the mac pro only supports one, contrary to product documentation. As Apple has yet to update their 30" display to native display port, this does include their 30" cinema display as of this writing.

    The long of it is that it appears that adapter is intolerant of its power source. The above makes the decision to use USB power instead of having a proper adapter a very BAD decision (not sure why they didn't just make a power adapter -- it's not like you are going to tote a 30" display around like a laptop). The result is that you get snow artifacts on the screen, which range from annoying, to distracting, and into the downright not usable range depending on how good or bad your power source is. Either the team who QA'd this product, or the pointy haired dude who ignored them and let it out the door should be fired. Apple needs to recall these and replace them with, I don't know, maybe functioning adapters? A tip -- a real DC power source that provides the consistant power needed by the adapter instead of reliance on an USB bus would work better.

    PS: That said the best power source I've found thus far is an Apple iPhone charger -- I happened to have an extra and tried it as well as a few other USB powered devices. So far it's the most usable of the lot, tho I still get significant snow and flicker even with it.

    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.

    Frequent screen issues

    • Written by from Vancouver

    I finally received my adapter last week. I use a 30' monitor at work and wouldn't live without it, so my new MacBook Pro has been in a drawer until yesterday (purchased the computer in October). I have purchased all 3 adapters for various purposes, but the Mini DisplayPort Dual DVI adapter is a great disappointment. On my Samsung 30', the screen flickers periodically or goes completely out of sync and this is incredibly annoying. I have tried a number of solutions as suggested in various on-line forums all to no avail. The only way to temporarily resolve the problem is to disconnect the adapter cable. If you regularly use a 30' monitor then I would delay purchasing a new MAC notebook computer until this problem is rectified.

    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!

    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.
