    Works well with Apple iPad 10W USB Power Adapter

    • Written by

    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

    • Written by from Toluca Lake

    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.

    Works well with high-power USB port

    • Written by from Palo Alto

    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!

    • Written by from Marietta

    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

    • Written by from Caguas

    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.

    A little bulky, but works fine

    • Written by

    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

    • 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!

    Fail: Cinema Display 30 and Macbook Pro

    • Written by from Franklin

    Flicker (off/then back on) every 10 minutes or so. Once a week, the screen goes to static. This is neither a faulty monitor, nor a faulty MBP. Hook the Cinema Display 30 to an old MB with dual dvi out, works great.

    This adapter is a faulty product, and Apple should recall and replace it. Many have the same problem.

    I expect compatibility when I do pay the premium prices for all Apple products.

    Apple, are you listening, at all?

    Connected to my Dell 30" U3011

    • Written by from SAINT LOUIS

    I reluctantly purchased the Dual-Link DVI to MDP adapter after reading the horrible reviews on this site and elsewhere. Yes, $100 to get full resolution seems excessive.

    I was able to get my 30" Dell hooked up and working properly. It works about 90% of the time, as I have multiple computers connected to the monitor, and sometime 1/10, when I switch the source input to my MBP, I see snow on top of my Mac OS screen. This is usually fixed by changing the input source to a different PC, then switching back to the MBP, or unplugging/replugging the MDP.

    For $100 it should work 100% of the time. 3.5 stars in my book.

    If you don't need USB pass through, you can pick up a cheap MDP to DP adapter from Monoprice

    Solved my Cintiq to iMac problem

    • Written by from Portland

    If you're having problems connecting a Cintiq to an iMac, this adapter worked for me.

    A regular DVI to mini adapter wasn't working to connect my Cintiq 21UX to my iMac. The Cintiq screen remained blank and was not recognized as a monitor by the iMac. A forum I found suggested this adapter would fix the problem. I was skeptical. In my admittedly limited understanding of how computers work, I didn't see how it would solve my problem, plus there are numerous bad reviews of this adapter. But once I used it to connect my Cintiq to the iMac, everything worked perfectly. I've been running it for a few days with none of the glitches some people seem to be experiencing.

    Working well with ACD 30"

    • Written by from Birmingham

    Recently replaced an ATI Radeon XT 1900 with an ATI Radeon 5770 in my Mac Pro 2,1. I was using 2 ACD 30" monitors so I needed this adapter for the second monitor since the 5770 has only one DVI port and 2 Mini Display ports. After 1 month, everything is working fine. No display issues.

    defective product, KNOWN ISSUE, demand replacement

    • Written by from San Francisco

    Hundreds of people, if not thousands, have suffered with this failure, perhaps Apple's worst product. If you look through discussions and the most helpful reviews, you will find hundreds of people with expensive 20+ and 30-inch monitors that will not function with this device and a new Mac. Do not buy this product.

    See Discussions Topic : Display flashes to solid black intermittently for solution

    As you can see from the post above, I believe I have a solution, jury-rigging an iPhone AC-to-usb charger with a USB extension to power the adapter. This brought back my 30-inch monitor. Also, the monitor works flawlessly with a 4 year-old Macbook Pro that has dual-link DVI native (no dongle/adapter).

    After spending an hour and half on hold, a senior tech admitted the KNONW ISSUE and is sending replacement now with firmware v1.02. I hope this resolves it, but others have said it is worse.

    Doesnt work

    • Written by from Santana de Parnaiba

    Just doesn't work, unusable. I have an early 2010 iMac and a Dell U2711 and it is totally useless. The screen keeps going to sleep for no reasen, keeps loosing signal and often the image becomes all noisy and unrecognizable.

    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.

    I HAD NO CHOICE

    • Written by from Houston

    I have been using my 30" ACD for over a year now with my 2 year old Macbook Pro. It had the DVI port so I was able to connect the monitor directly. I decided it was time to upgrade and I bought a new i7 17" Macbook Pro. Guess what? No DVI port. So I had to buy the Dual-Link DVI Adapter. They should have never taken the DVI port off of the Macbook Pro. So here I am stuck with either a double image (like that you see when looking at 3D without the glasses on) or blue/green/red interference lines.

    So I took the Macbook Pro, monitor and cable to the genius bar. Some genius. After trying 3 cables I was told that there was nothing he could do and that I should sell my monitor. THERE IS NOTHING WRONG WITH THE MONITOR!!!!!!! He told me I was taking up too much of his time as he was only allotted 15 minutes to work out the problems. He let me pick the best Adapter and sent me on my way.

    NOW WHAT??????

    I am calling Apple tomorrow . . . . .

    Until the next post :(

    Pricey but does the job fine

    • Written by from Chicago

    It is pricey, and honestly it is one of the things that help me off from buying a new macbook pro. Unlike some of the people here that have had issues though, I am using this with a new 15" macbook pro i7 and a Dell 3007WFP-HC 30" monitor for the last week and have not had any issues. No flickering, needing to restart, etc. I am also not a fan of this taking up another usb port, but if you use a good powered usb hub, it isn't really an issue. i don't see many alternatives for this and it works fine for me.
