    very very unreliable

    Almost every day I have to unplug this device from my Imac 27" Retina, and plug it back in to reboot it to power my external Benq monitor to unscrew the image on the Benq. What a load of rubbish!

    Stops working every so often

    As the other reviewers state, this product will definitely shut off every so often. You then need to disconnect and reconnect either the DVI connection or the USB/mini-DisplayPort side. I've used this thing for years and it been very random for me. Sometimes days go by with no problems. Sometimes the thing needs to be reset 10 times in one hour. Mac mini feels like a somewhat neglected product and this peripheral doesn't help that perception.

    The worst product I've ever bought

    This is the worst product I've ever bought. It works fine for a while until the screen goes black and I have to unplug and replug the cables to fix the problem. There's also intermittent flickering. DO NOT BUY THIS PRODUCT.

    Adapter Type: Apple Mini DisplayPort To Dual-Link DVI Adapter
    Adapter Firmware Version: 1,03

    Frequent problems to the point it's unusable

    From the start of using this product there was the occasional problem where the external screen would boot with a lot of static, then turning it off and back on would sort that... okay. Next got a bit more serious where the external screen would have red lines appearing all over it, then it would slow down and fade away. Pulling the cables in and out multiple times eventually sorted that. Finally the screen would disconnect completely and moving the cables around would fix that however this time even when making as little movement as possible at the desk it will randomly drop off then kick back into action or just completely drop dead. I know it isn't the monitor as connecting directly through DVI from my PC works without fault every time. This has happened on my mac mini and then my Macbook Pro (Retina, 15-inch, Mid 2015). Oh well, time to go cable hunting I guess but won't be buying that from apple again.

    144Hz White spot display problem

    I have BenQ 2430T. I use Dual-Link DVI Adapter. when I change to 120Hz, the display is ok. but When I change to 144Hz, there are too many white spot on Display. How can I solve this problem. But when I change to 144hz in WIndow7(bootcamp), it's ok. not ok in osx.....

    once did work

    Bought this with a new mac air 2013 to plug into my Eizo cg240 and it worked that year.

    After travelling for a while and applying recommended OS updates I arrived home to plugin to Eizo monitor to find the Mini DisplayPort to Dual-Link DVI Adapter no longer worked!

    Upgrading to OSX10.11 and Mini DisplayPort to Dual-Link DVI Adapter on my mac air 2013 is blind to the Eizo monitor.

    Waste of money.

    Works great

    Have this plugged into my Late 2011 Macbook Pro, Hazro HZ27WD 27" 2560x1440 monitor and a powered USB hub. Works flawlessly so far and I didn't have to configure anything. Shame these kind of adapters are so expensive :(

    DOES NOT WORK AND CAUSES HEADACHES

    Too bad Apple ! $100 for this bought a very nice (and expensive) 27 LG Display Color Prime... Now I have all sorts of distortions and flickr.. Image is unusable at most times and I also get black screen from time to time. LG won' give me any support as they do not trust the adapter... too bad! DO NOT BUY THIS THING - worst Apple product ever. FULL RECALL NEEDED (and why take an usb port for power???) --

    Worked for 8 months then died

    This adapter was used to connect the Mini DisplayPort of a May 2013 Mac mini to a 2012 Dell dual-link DVI monitor (2560 x 1440). The adapter stopped working after only 8 months of use.

    It works with New Macpro 2014

    I almost did not buy this due to all the negative reviews but i had no choice. I purchased the new macpro 2014 but needed a solution to run the 30 inch cinema display at max resolution 2560. The adapter works perfectly. I had no issues.

    Gray background flickering

    Wow, I read all the bad reviews about flickering issues but went ahead and bought the expensive adapter anyway, as I am not aware of any other solutions to connect my new macbook pro to my cinema display.

    The grays are flickering constantly. I just can't believe that Apple hasn't corrected this problem and keeps selling these expensive, faulty adapters. My adapter is brand new, it has firmware 1.03.

    It's just unbelievable that it's not possible to connect a high-end *Apple* macbook pro with a high-end *Apple* display. The computer and display are among the most expensive on the market, I paid thousands of dollars, and the image quality with the flickering is just unacceptable.

    Usually I'm too lazy to write reviews, this is the first one I write, but this is just crazy.

    Works, but...

    There are some definite issues with this adapter. I am using a new 2013 MacBook Pro, 16g RAM, 512g SSD.

    I have a Dell U3011. The adapter works "most" of the time, but several times during the day it will go black for about 5 seconds and then come back. However, sometimes it goes black and comes back with heavy SNOW. At that point, I have to turn the monitor off for 3-5 seconds and then turn it back on. This has worked so far.

    However, I have several other USB devices connected to the monitor, so when it goes off, so does everything else.

    It's clear to me the adapter has a design flaw someplace. I suppose since it's new I could take it back to the apple store and get another one. But since this is a common problem with Mac users, it probably will not do much good.

    Does not work ?- here is the solution!

    Don't bother with this flaky adapter - buy another brand. I now have an adapter from Dr. B*tt, it works like a charm... rocksolid with my 30" Dell 3007WFP using MacMini Late 2012.

    Serious Noise (static)

    Blacks are a sea of static. I've taken back the adapter twice to replace it - but it appears that electrical interference is a design feature of this device.

    I'm worried that this adapter will be the only way to connect the new 2014 Mac Pro to the (otherwise very good) apple 30" cinema displays.

    Works fine on Dell 3007 and latest MBA

    I've had very few problems with this running my Dell 3007 monitor. I also run 2 other screens via display link (so 3 external including this one).

    A lot of people complain about the cost of these, but if you look at the market place and other manufacturers prices, the apple cost of one of these is actually OK. As the signal conversion between dual link DVI-D and mini DP is not straightforward, there is a chip inside these that has to convert the image, and if running at 2560*1600 at 60Hz, that is 245,760,000 pixels per second it has to do - hence the power requirement of USB and the cost.

    Keeps turning off and on

    Using it on a brand new 2013 Macbook Pro into a Dell 2713 - and the screen keeps turning black (off) then on for a minute before it "stabilizes".

    2560 x 1440 solution for Macbook Pro

    I have dell screen with 2560 x 1440 and try different cables to get maximum resolution.

    I called Apple, Dell and other people about solution but no body told me this will work.

    I will recommend for High Res screens. Give 3 stars because of price too high.
    I could buy Apple TV instead of Adapter. Where is Quality in Value???

    Dual link Dvi - Expensive

    I bought this adapter for my korean PLS monitor and as many says it did give me some troubles when i woke the computer up from sleep. This is caused due to the loss of power in the usb port and when the computer wakes the adapter is off. To counteract this problem, try to hook the usb to a normal iphone charger that wont power off when the computer goes to sleep.
    Works good but way to expensive..

    First truly awful Apple product I've ever owned.

    Sorry to say it, but all the negative reviews are right. This adapter is really great at displaying snow all over your display with what's actually supposed to be there just barely showing through!

    When it works, it works great. Problem is, it displays snow about 20 times a day.

    Total fail. :(
