    The prefect solution for high-resolution displays

    • Written by Ben B from London

    I used two of these adaptors to connect two 30-inch Cinema Displays to my 2011 iMac. Setup is easy and the adaptors work perfectly (note that you must connect both the DisplayPort/Thunderbolt AND the USB connectors to the Mac, as the power is supplied over USB). These adaptors are annoyingly expensive, however since they are literally the only devices that support the 2560x1600 resolution of the 30-inch Cinema Display, I don't feel I can complain too much about the cost - worth every penny!

    Expensive but it works

    • Written by D G G from KINGSTON UPON THAMES

    An expensive adaptor but at least it works (MacBook Pro, 2012 and a 30" Cinema HD monitor). Reading the other reviews made me worried I would be returning it immediately but so far it seems to be more than fine - it's great.

    Beating a dead horse

    • Written by Ken W from Chester

    I recently purchased an iMac 27" and wanted to use my older 30" Cinema Display as a second monitor. After ready many sources I opted to buy the Mini Display Port to Dual Link DVI Adapter. Once I tried to hook this up I found there were no mini display port on the iMac. So now I suppose I must buy another adapter to hook mini display plug to firebolt? Or is there some other adapter I need to make this work? Planned obsolescence I say.

    Late 2012 iMac bootcamp for gaming setup

    • Written by Steven D from Holt

    I use this cord to connect to a 144hz monitor I got for gaming on my iMac 2012 because I got tired of the constant screen tearing with ALL my games I played on the native monitor. I thought that this would be a good compromise because I wanted to get a second monitor anyway for things like watching 1080p videos in native quality or reading articles without having to squint. The primary purpose of getting this monitor was to play games at a higher refresh rate though because the iMac is limited to like 59 hz or 60 hz (which caused the tearing). This adapter has pretty much completely eliminated that screen learning problem and I can play games at higher frame rates and settings as a result. It does have some caveats though. The snow problem mentioned is very irritating but it seems to ONLY happen in the mac partition. It is corrected by unplugging and replugging the mini display plug for me. The other issue is that it is limited to 120 hz gaming, so I can't take advantage of the full 144 hz my monitor can dish out. When I try to set it at 144, it freaks out and goes to black for extended periods of time before defaulting back to 120. Expensive is the last con, as I would have given 5 stars easy even with the other problems if this had been $50. I would say do your research, make sure you know WHY you should or even need to buy this before getting it. This is a good solution for me though because I can play games at 1080p without stressing my iMac to pieces, and get 120 hz for smooth gameplay and seriously extend the life of my aging mac that can still game.

    Adapter is intermittent

    • Written by Matthew A from Orlando

    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.

    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

    • Written by Robert M from Cedar Park

    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

    • Written by Håvard L from Oslo

    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.

    Frequent problems to the point it's unusable

    • Written by George D from Glasgow

    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.

    once did work

    • Written by Matthew A from Point Vernon

    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

    • Written by Edmon L from Hong Kong

    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

    • Written by Kevin T from Singapore

    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

    • Written by Daniel C from Australia

    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.

    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

    • Written by Luan D from BROOKLYN

    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.

    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

    • Written by Kevin C from Ongar

    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!
