    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.

    DVI-D only

    Please be aware that the DVI female connector is DVI-D, lacking the four little holes that would make it a DVI-I cable.

    Poorly engineered, but flicker issue solved!

    This device is poorly engineered; as with many other reviewers, for me it flips out regularly, flickering, losing sync, showing rainbow snow, etc. However after dealing with this for a long period of time, I've finally found a reliable solution.

    The device is unable to get enough power from the macbook pro USB port. So unplug the usb cord only, and plug it into an external power supply that has some good current. I used a 2-amp / 10 watt USB charger. Obviously, leave the mini-displayport plugged into your laptop. Doing this, the display has been 100% reliable, no issues whatsoever. I was ready to get rid of my 8 year old 30" dell monitor, assuming it was the issue, but am so glad to have learned that it was only the adapter!

    This product should have never been sold as-is, but with this workaround, it works as expected.

    Works flawlessly

    MBP 8.1 / OSX 10.9.3 / ACD 30" / 1.03 firmware [adapter].

    No issues, at all.
    This adapter can use significant power.
    I'm powering it with an Apple 10W USB charger as a dedicated USB power source.
    If you have problems or have other USB devices that can use significant power, a dedicated supply can make a difference.

    works as designed

    I'm pleasantly surprised how this adaptor resurrected my Apple 30 inch Cinema Display. I've tried the adaptor with the Display on these Macs: early 2011 MBPro 17 inch, mid 2012 rMBPro and a 2013 Mac Pro. No flicker, full resolution and no problems. The adaptor connected to the thunderbolt port on all three Macs. Of course the only draw back is on the Macs with one thunderbolt port that the port is 100% tied up with the monitor. I imagine a thunderbolt dock could be used and daisy chaining a device for expansion.

    No problem at all

    After reading the many bad reviews I decided to call apple and see what they have to say. I was told there was no reason this should not work with my new LG Ultrawide 29" Monitor. If it did not work I could return for a full refund with in 14 days. On that information I decided to give it a go..

    It works perfectly so far. I hope it stays this way!

    Works Perfectly

    I have used this adapter every day for four years with my MacBook Pro. It has never caused the slightest problem.

    Works perfectly: Mac Mini 2011: 27" Korean reject, and full 1440p

    If you're reading this review, chances are you've banged your head against the wall trying to figure out how to hook up a computer to a 1440p display. I read all the reviews here, and bought the darn thing anyway.

    It works on my 2011 Mac Mini like a charm.

    The only thing I had to do was restart my computer and it worked. The resolution is 2560 x 1440, and adjustable.

    I hooked my mini up to a 27" Korean Thunderbolt knock-off I bought on craigslist.

    Lastly, if you're confused about the length of the cable, and all the ports, just plug the mini-display port into your computer WITH THE USB PORT into your computer. This is required, as high resolution displays draw power from your computer. As to the USB port on the brick itself, that's anyone's guess.

    I originally rated this at 4 stars, but I added the fifth after doing some math. I paid $380 all-together for what is essentially a $999 Thunderbolt display. This thing is gorgeous.

    Hope this helps.

    Works Just Fine

    Purchased 2 of these for a 1st gen Mac Pro with an unsupported ATI Radeon HD 5870. Works flawlessly. Have the DVI port to HDMI on a 32" LCD TV. The 2 mini displayports adapters plug to vid card and then use DVI to HDMI cable to 2 27" hdmi monitors for 3 monitors total. No issues! Just not sure what the extra usb ports next to the dvi ports are for?

    Works Perfectly

    I am using this cable to connect a new Mac Pro (2013) to a NEC monitor. I have attached the associated USB cable to an Apple 12W USB charger and this arrangement allows full resolution of the monitor.

    Thanks to other reviewers, I got this to work beautifully.

    So here is the scoop (although some of my facts might be a bit off).

    The computer industry was going along fine with DVI outputs on computers, but they produced these wonderful 30" monitors with 2560 X 1600 resolution that the standard outputs wouldn't handle. So they developed the Dual Link DVI connectors and standard so the computers could support enough throughput to power these monsters.

    A bunch of them were sold by various companies. Mine is a Hewlett Packard LP3065c, but Apple sold one and a number of other companies sold them as well. I got mine in a package deal from Costco, others bought the monitors for graphics manipulation or photography applications or what not.

    Then the standard became HDMI, which, although a step up from standard DVI output, was actually a step back from Dual Link DVI. For the most part those of us who owned these beautiful 30" monsters were now orphans--HDMI would only support 27" monitors.

    At least that was true until the 4K standard came out and and then new computers started packing extra high powered graphics cards and DP ports to support them.

    Apple developed the Mini Display Port to Dual Link DVI adapters to allow people who had the super-duper 30" monitors to hook them up to the new systems that could now support them.

    So I bought a Mac Mini to use with my HP LP3065c and got the adapter to hook them together. Most other reviewers had a hard time getting the adapters to work. Mine is the 3rd generation one with version 1.03 firmware, so that might make a difference. The problem seems to be from a lack of power.

    The Dual Link DVI adapter has two plugs on it: The mini display port plug that carries the video signal, and a USB cable to provide the power to the whole mess. Unfortunately there sometimes isn't enough power in the host computer to take care of it. The solution is to not plug the usb into the host computer, but to use a little usb power pack. I used my I-pad power pack ($19.95 at any best buy or Mac shop). When I did it all worked perfectly. Another reviewer said that you need one rated at least 1 amp. The I-pad one is rated 2.4 amps which is more than enough power.

    I didn't even try to hook the USB up to the Mac Mini. I just used the power pack when I first hooked it up and shezam, it all worked perfectly and my Mac Mini's display is shown beautifully on my 30" screen.

    If you have one of these monitors, you can't take advantage of the graphics by using the HDMI port. You need either one of the new display port computers, or one with Dual Link DVI output, which is usually only found in higher end graphics cards.

    I did have one incident where the monitor refused to display the output of the Mac Mini, and that was when I bought a new one of the little adapters from Best Buy. The new adapter didn't work the 2nd time around, so I swapped it back out with the old one from my I-pad Air, and everything worked fine again.

    Good luck with this product if you are buying it.

    I kept all my receipts and boxes just in case it didn't all work. You would be wise to do the same thing since YMMV.

    Surprisingly, I had no issues!

    After reading all the reviews on here, I was terrified to try this cable out. But since I just bought a new 2013 macbook pro retina 15" and there are no other options to use it with my mac 30" cinema display, I bit the bullet and bought it. I'm actually surprised that I've had no issues with connection and resolution. Works just fine (for me at least!)

    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???) --

    USB Port Stopped Working after Mavericks Update

    Adapter worked well with my 2011 13" MBP on Mountain Lion. USB port on adapter no longer works after upgrade to Mavericks. Both USB ports on MBP work when not docked.

    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.
