    Unacceptable and Apple Support is Unable to Provide Solution

    I purchased a Makpro with two graphics cards supporting a total of six monitors and four of these adapters for a trading application. Every now and then a monitor will go blank at random and when that happens all the monitors fail to blue screens and when they reinitialize, the contents of all screens are scrambled. Support has asked a lot of questions but has not provided any solutions and now is not responding to my emails. I will have to return the computer and adapters and go back to the dreaded PC's (which have other issues but not this one). Too bad, otherwise, the computer is quite good. I have 8 Macs total so I am not new to them.

    Adapter is unreliable ... lots of snow

    I have a Del U3011 display that I use at home and connect my 2009 Unibody via the display port to the display. The cheap DVI Display adapter would not let me get a resolution greater than 1680x1050 and so I sprung the $100 for the Dual-Link DVI adapter.

    It is a very poor quality device as I generally have to change resolutions to get the "snow" to disappear. When it is working its fine but its definitely not worth the $100. The display will also intermittently cut out (blank) for up to 20 seconds and then start working again. I know its not the monitor as I also use it for a Windows box and the Dell display works flawlessly with that system.

    I'm a big Apple fan but on this device they get a major thumbs down.

    Terrible Quality

    For $100, you'd expect a reliable piece of electronics. These adapters have done nothing but break and act completely unreliably.

    Works for Me

    I've had absolutely no problems with this adapter. I'm driving a 30" Apple Cinema Display with an early 2010 Mac Mini with the 2.26 GHz Core 2 Duo processor and the NVIDIA GeForce 9400M graphics processor. Some have said that the adapter needs to be driven with its own power supply, but I'm not using one. Some have said that the adapter needs to have recent firmware. Mine came with firmware version 1.03, which is relatively recent (I bought the adapter in early 2010), so this might be the key as to why it works for me but not for others.

    It doesn't work, however, with my Thinkpad X220 laptop with a Sandy Bridge dual core i7 processor with integrated Intel graphics. With the laptop, I get the flickering that others have described. I had to use a non-Apple DisplayPort to mini DisplayPort adapter, so the problem may be with that adapter, although this is very unlikely. I'm not taking points off for this because Apple clearly states that its adapter is for use with Apple computers only.

    Works perfectly with 2010 MacBook Air

    Worked perfectly with my MBA 2010 over MiniDisplay. I've been using this for a week and so far none of the flickering problem (yet!) with my Apple 30" monitor.

    Like other say, maybe it's the new firmware which solves all problem. So make sure you get the latest firmware (I believe mine was 2011-January update).

    New IMac + Dell 3007WFP

    Like others I was leary about buying this device, given all the bad reviews. But decided to take a chance and glad I did so far. It was easy to install and setup. I did see it flicker my screen to white and back again, but this only occurred once. I do have firmware 1.03.

    No worries!!

    I agonised over buying this because of all the negative reports but really had no choice to try to get my new Dell U2711 display to work at its best resolution, 2560 x 1440. Much to my relief, when I connected up to my MacBook Pro 17" this evening, it works perfectly!!!!!

    Work GREAT.

    I have three of these and am planning to buy a fourth one today for my research office. They are attached to my 30 in HP LP3065 monitors at different offices and I use them with my MacBook Pro machine without a problem:
    Model Name: MacBook Pro
    Model Identifier: MacBookPro5,2
    Processor Name: Intel Core 2 Duo
    Processor Speed: 3.06 GHz
    I wonder if the issues others are having are due to using them with an Apple Monitor or bad video outputs? I use the HP monitors since they have three HDMI inputs built in so they display the desktop information most of the time, then switch to the laptop when I need it.

    Mini Display to Dual Link DVI adapter is really bad

    It troubles me greatly to think that a 2007 Macbook is better than a 2011 simply for it's easy ability to plug into a Dell 27" display. The Apple Adapter requires all sorts of tricks to get to work. Apple should recall this product as it is just wrong. I want a refund (Not Fit For Purpose)

    Works well with 17" Macbook

    This adapter works fine with my 17" Macbook Pro. Note that the adapter draws power over the USB connector, so that must be plugged in even if this is used with a non-dual-link display.

    Works well with Apple iPad 10W USB Power Adapter

    TL;DR: If you want to use this, you really need to use the Apple iPad 10W USB Power Adapter to power it.

    This is an update to an earlier review.

    This thing (evidently) requires a lot of power. Fairly recent Macbooks shuld be able to power it, though generally only if you aren't using the other USB connectors and, in particular, if you don't plug in an iPhone, iPod Touch, or iPad (particularly an iPad). I've tried using an external powered hub, the AC adapter that comes with an iPhone, and the adapter that comes with the iPad. The 10W iPad charger is the only thing that results in no connection problems or sparkles. With the 10W connector, it's absolutlely solid. Clearly, they should have inlcluded it and told people not to try it without it. The way the USB connectors on a Macbook work, you'll get various results not only depending on what else you plug in, but the order in which you plug them in.

    Apple would have saved themselves a world of hurt if they'd just included the 10W connector.

    Terrible performance under the best conditions

    This adapter causes the Apple 30" Cinema Display to turn on and off after being plugged in for more than an hour. It worked better that this initially, but after owning it for a few months, it started causing problems. The flickering occurs every one to 30 seconds, rendering the display essentially useless.

    I seldom rate any product with one star. Generally, it seems overly harsh. In this case, though, the product is so expensive, so cumbersome, and works so badly, it's really the only review I could give.

    Worst product I have ever got. Very unstable

    Connect to dell 30" to my new macbook pro with this adapter. Every hour I need to replug it because the display turns to something unreadable. Snow noise, zig-zag, etc. The worst, bluetooth keyboard and mouse suddenly stop working. Suggest others not to buy it!

    Works well with high-power USB port

    I've had this for a while and had the same trouble many people mention. It doesn't work at all without the USB connector. Moreover, it really wants a high power USB port such as found on macbooks. I think this is why so many people have varying success. If you plug it into a hub, you'll get anywhere from nothing to sparkles. The macbook USBs have higher power (as needed by iOS devices). If you use the AC USB adapter that comes with an iOS device, I think you'll have far better results.

    Awesome!

    Works flawlessly! I got two of those so that my 5770 supports all three displays.

    Side note: plugging in the USB part of the adapter is required, as it may cause flickers when not powered.

    Mini Displayport to Dual-Link DVI gives static

    I have a 2010 model 17" MBP with a Dell 30" monitor and the adapter causes static on the screen when the MBP is woken up from sleep. The problem is fixed by unplugging the adapter from the MBP then re-plugging, sometimes 2-3 times. MBP works fine with other monitors; monitor works fine with other computers (without adapter). Clearly a problem with this product.

    Don't waste your money and time on this product.

    Using a mid 2010 Macbook pro and 30" Dell screen. Everyday for 8 months I had to unplug and replug the dual line or turn the monitor on and off to get it to work. For 8 months I have endured this useless, expensive cable but what choice did I have? I didn't want a glossy 27" monitor. After taking the cable back to Mac several time and even buying a new dual link cable, still no better. Replaced my Dell with the latest version 30" and still the screen was static or black. I was even thinking of buying a new laptop.
    But the answer is a simple- mini display port to display port cable. $13.75 for a 2m cable. Works perfectly and gives 2560 x 1600 res. Makes me sick I wasted my energy and time. I still can't believe Apple would sell such a bad product after owing Macs for nearly 30 years.

    Still flickering!!

    I thought after more than 2 years since reports of flickering with this adapter became apparent Apple would have fixed the problem. Unfortunately I am experiencing the same problem connecting my Mac Mini 2010 to my 30 inch Apple Display. I am trying to ignore the flickering. Its probably because the 30 inch Display is old technology and not really compatible with current Macs.

    A little bulky, but works fine

    Plug-and-play functionality on a Matrox Triplehead2go 3840x1024 at 60hz. The USB port on the Dual-Link adapter didn't have enough power for the Matrox though, so I had to plug directly into the laptop.

    Worst Apple Product

    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!
