    Adapter is intermittent

    I still haven't found any of these adapters that work properly and continue to work properly. The Apple version of this lasted about 18 months before it started displaying green lines through any of the black areas. It also occasionally just arbitrarily decides to show a black screen, flickering back and forth between working and not for no apparent reason. I suspect that having USB power the adapter was a poor design choice, as it seems that it's a voltage drop that causes the problem. I've tried two of these adapters with varying success. My recommendation? If you are given a 30" display and only have a Thunderbolt or mini displayport to plug it into, just move along.

    Works in Macmini Late 2012 with 10.9.5

    Im happy with this Mini DisplayPort to Dual-Link DVI Adapter, its working, the native resolution of my monitor is 2560x1440, and looks great!!! But the price... is expensive.

    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.

    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.

    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.

    Works Great - Some tuning Required

    I just upgraded my PC to a MSI 7970 Video card and discovered to my dismay that it required a Dual DVI to Mini DP Adapter to push 2560x1600 resolutions to my sweet sweet 30 inch monitor. After reading the problems on these forums, I still felt that the device should work as advertised, so I gave it a shot.

    To my dismay, while it worked perfectly I do experience the distorted screen as many people have reported.

    However, after giving it some thought, and watching it's behavior for some time, I realized that the distortion only occurred everytime I left the room for extended periods. The only thing that kicks in at that time (Over an hour) was my power saving mode for the screen. Since turning off Power saving mode, i'm no longer experiencing the screen distortions as reported on these forums.

    Great Product, though it is quite expensive for a simple adapter.

    Flawless - don't heed the others

    I was too very reluctant to buy one after see many widespread negative reviews of the product. But I went ahead and purchased one for my 27" U2711 Dell Ultrasharp and 2011 15" MBP.

    For all the nay-sayers, they're probably using the normal DVI cable with is INCORRECT. Any resolution larger than 1900x1200 requires DUAL-LINK DVI. The cable may appear the same to the lay person, but there are very important differences.

    Make sure you have a DUAL-LINK DVI cable and you will enjoy your large resolution external display.

    Dissappointed

    This adapter only works for does not work as specified which is for anything above 1920x1200. I have tried this adapter using: Dell 3007WFP, MacBookPro5,1 and Mini DisplayPort to Dual-Link DVI Adapter firmware version 1.0.3.

    I am really hoping that Apple will fix these issues because a lot of people in Tech Writing, IT, Software Development, Engineering, and Movie/Photo editing require 2560x1600 on 30" monitor (whether generic or Apple manufactured) making their day to day lives easier.

    Please help us Apple! :-)

    Another fail for Dell 3007WFP-HC

    I got this a while back for my 15 inch Macbook Pro. Although 2560x1600 looks amazing on OSX, there was so much obvious distortion that the adapter obviously has a design flawed. I tried jigging the cable numerous times. Overall, it just doesn't work. Judging by the other reviews, seems like Apple completely ignored fixing this problem. If this happens to you, Apple will give you a full refund, so save your receipt. It's a shame though, I've been using Windows all these years because of this issue (and some other), while I could have been on OSX.

    It's Christmas time on my 27" Dell monitor! (Festive colored snow)

    So, we've got 3 of these in my office, connected to our Dell 2560x1440 monitors, everyone experiences sporadic connection issues. Just snow for me, but it's still really irritating, especially for a 99 dollar cable with an Apple logo on it!

    Don't waste your money

    I have an i7 Mac Mini and a Dell 27" monitor. EVERY time the Mac wakes from sleep, the screen is all snowy, needed me to switch the monitor off and back on. On a couple of occasions the screen will not clear until a full restart, and one a few occasions, I have had the Mac lockup showing the "Please Restart Your Computer' screen.

    Absolute rubbish!

    Why Hasn't Apple Fixed This Yet?

    total failure, this adapter will cut off, have to be reset hundreds of times, and cause more stress than it could ever be worth. TOTAL RIP OFF.

    Firmware Version 1.03 does not eliminate "flickering snow" problem

    I tried this adapter with a NEC PA271W monitor. I am using a 17" MacBook Pro (2011 model, 8GB RAM) with OSX 10.6.8. Initially, I was experiencing the "flickering snow" problem about 25% of the time when my computer woke from a sleeping state.

    It was very frustrating to have to cycle the monitor off and back on or to unplug it from the computer and then reconnect it so often to clear up the display.

    It was able to reduce the frequency of the problem by connecting a USB cable between the monitor's Upstream USB Port 1 and the USB port on the Adapter. But this did not eliminate the problem.

    NEC tech support sent me a Mini DisplayPort-to-DisplayPort cable (NEC Part Number PA-MDP-CABL, price $29.99). They also instructed me to connect an A/B USB cable between the monitor's Upstream USB Port 1 and the computer.

    So far, this has fixed the problem.

    This cable does support the Monitor's highest resolution, 2560 x 1440, 60 Hz.

    I do not know how well this particular cable will work for non-NEC monitors. There is a latch on the end of the cable that locks into the DisplayPort on my NEC monitor. I do not know if the DisplayPort connections on monitors from other manufacturers have the same fitting.

    Can't play rented iTunes content, and shows "snow" on blacks

    This adapter lets me connect my mid-2011 (Thunderbolt) MacBook Air to my old 30" Apple Cinema Display. It works for the most part, but it has significant flaws:

    1. Pure black areas show a little "snow" on the Cinema Display.

    2. The adapter doesn't seem to support HDCP, which means I can't rent a movie in iTunes and play it back on the 30" display. This is annoying given that I'm using an all-Apple setup, and renting iTunes content! (This does not seem to affect purchased iTunes video content, though -- just rented video content.)

    Neither is a deal-breaker, but both are annoying.

    New cable with Firmware 1.03 did the job!!!

    Followed the advice of entry: Aug, 2011 from MK Atlanta. I "Screen grabbed" (Cmd + Shift + 4) and printed MK's entry, and information about my Mac's hardware, which showed that I had a old 1.02 firmware cable. Took all the printed information and old cable to Apple store and they exchanged it, no problem. We weren't able to test it as the store was packed and everyone was using the monitors and laptops etc. But as soon as I got home, connected the new cable no problems, no snow, no flickering....Halleluiah!!! Why can't they post this, or send us an update? My new Subaru has had some computer updates since I bought it in February..... I get a letter, take it in, update, end of story. (note: I have a mid 2010 MacBook Pro)

    Expensive and Bulky

    For the price, this adapter should include a dual-link DVI cable. The adapter doesn't work properly unless you have the very latest version of the cable (with 1.03 firmware), so don't look for used cables on eBay. The adapter is bulky and requires the use of a USB port (though it does have a USB port on it). If you have a MacBook Air, and especially if you want to use an Air SuperDrive, you will have trouble connecting everything at once. This is because the SuperDrive will not work with USB hubs.

    Sadly, this is the only option available for some people depending on their display. If possible, a Mini DisplayPort or DisplayPort connection (with adapter) is a better bet for hi-res work.
