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

    • Written by from Seattle

    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.

    I thought my Beloved 30" Cinema Display was toast but it turned out it was this adaptor. I got lucky, I only need to replace the adaptor once.

    Surprisingly, I had no issues!

    • Written by from Long Beach

    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!)

    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..

    USB Port Stopped Working after Mavericks Update

    Works fine for me

    • Written by from Zürich

    I recently got one of the new (2013) MacPros and needed one of these adapters to connect my old 30" Cinema Display. After reading the reviews here, I was cautious whether I might be running into the problems described here.

    So far (about 10 hours of continuos use), I have not seen any of the symptoms listed. The adapter does exactly what it's supposed to do (i.e. make the full 2560x1600 resolution usable on my new MacPro).

    Keep in mind that the adapter is quite bulky and big. It also definitely has some electronics in it, possibly to split the combined signal it receives from the machine into two DVI channels, so it's another active component that can break at any time.

    30 inch Cinema w MacBook Air6,2 13 inch monitor works...

    • Written by from LIVINGSTON

    Just purchased one of these, my 2007 MacBook Pro 17 gave up on life and I needed to get my MacBook Air connected to my 30 Inch Cinema HD. I was some what discouraged with the high number of negative comments on this adapter. I've had it running my Cinema for a couple of days with no problem what so ever with the Graphics. This morning to test the USB I plugged a 160GB external USB drive into the adapter USB port, no luck. Apparently there's insufficient supply for the driver enclosure. I unplugged the Mini adaptor USB from my computer thinking I'd just use the USB direct, immediately the Cinema display went dark. MacBook Air is still showing the external display on the menu bar but it's no longer working. Plugged the Mini adaptor USB back in the MacBook Air, Cinema came back on. So, button line for me was I needed the Graphics capability, I got it, paid through the nose for it though considering the USB port is about useless. The adaptor in appearance shows Apple's quality build however seems the USB port limitation should be noted well enough so folks knew that right up front. Maybe I missed that in the spec's.

    Worked for 8 months then died

    • Written by from KANEOHE

    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.

    Works Great! People with 1-star reviews were using incorrectly.

    • Written by from Palo Alto

    I'm using this adapter right now from my 15" mid-2012 rMBP to a QNIX QX2710 LED EvolutionⅡ2 27" 2560x1440 PLS Monitor, which states on the seller page on ebay that it is "not compatible with laptops and mac computers," and that "Internal GPU, APU, and low-profile GPU are not compatible." The rMBP uses a GT 650m low-profile GPU. It later states not to use a port converter (eg mini dp -> dual-link dvi), this warning does not account for active adapters like this one, which uses a usb plug to provide additional power. If cabling permits, plug the usb port INTO AN OUTLET to ensure that it's receiving sufficient power. In any case, don't plug it into your laptop, run it off battery power in integrated graphics mode and write a one-star review when it doesn't work.

    Works fine with rMBP/Mavericks and 30" Apple Cinema Display

    • Written by from New York

    Haven't had any performance issues with this set up. Minor negatives: The screws on the Cinema Display cable are not long enough to reach the threads in the adapter, so the connection is unstable. Secured it with some rubber bands and it hasn't been a problem. And of course the Firewire ports on the display are unconnected. Maybe an additional (Thunderbolt to Firewire) adapter would work, but haven't tried this.

    Gray background flickering

    • Written by from Cold Spring Harbor

    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.

    Make sure to get the version with Firmware 1.03!

    • Written by from San Jose

    I use this adaptor on my 2010 Macbook Air to connect to a Dell 30" monitor. The first adaptor I bought would flicker and cut out, but after reading this (support dot apple dot com/kb/TS3232) I returned it and got a newer version with firmware 1.03 on it and now it's FLAWLESS. Zero problems and worth every penny.

    Works, but...

    • Written by from Pepperell

    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.

    hit and miss

    • Written by from Salem

    I have two of these, both connected to different Dell 30" monitors and used with the same 17" macbook pro. One works well with no problems. The other one requires unplugging and plugging back in the USB cable, or the display connector cable, 98% of the time when first connected, or when waking from sleep. The monitor comes on, but is fuzzy like a snow storm and the unplug/replug (sometimes 2-3 times) is necessary to get a clear picture. Its annoying, frustrating, and the first really poor product I've purchased from Apple in my 19 years of business with the company. Given the high price of the cable and that its OEM, I expect more. I've put up with this for over a year--it time to start searching for an alternative.

    Just buy the thing and if it doesn't work, return it!!

    I hesitated to buy this because of all the bad reviews and then just thought to my self: "Just buy the thing and if it doesn't work, return it!!"

    You definitely have to have the usb chord plugged in to work.

    I'm updated with all the latest software on my early 2011 MBP. And it WORKS PERFECTLY! No problems at all.

    With my older 2007 MBP the screen would show those horizontal streaks of light that others have complained about. And this was BEFORE i got this adapter.

    The streaks would get worse and worse as the monitor was left on longer. So far this has not happened at all with the new adapter.

    So:

    Just buy the thing and if it doesn't work, return it!!

    Still problems with this product: really needs an external power supply

    • Written by from London

    Initially (i.e. for the first week or so) this product worked on an NEC Reference 3090, with occasional drop outs to lower resolutions running with a brand new MBP 15" (late 2013). Today however, it became unable to output at the native resolution no matter how many shut downs and device disconnects I did. In desperation I read the reviews and noticed the threads pointing out the problem with the device not receiving enough power from the computers USB port. I tried with a spare iPhone charger and a M-F USB cable...hey presto immediately back to full resolution!

    This product works, but not as described (i.e. really needs a dedicated external power supply). Very disappointing and proves that not all Apple products 'Just work'. Wait until the Mac Pros arrive and everyone has to use them to connect to high resolution monitors....Let's hope those USB ports have more power.

    I'll see how stable it is with external power and repost if I have fresh problems.

    BTW I checked and this is ver. 1.03 firmware.

    Works with my Mac Mini

    • Written by from Bainbridge Island

    After seeing all the negative reviews for this display adapter, and the high price, I was hesitant to order, but I really had no choice if I want to get full resolution out of my 30-inch display.

    I'm glad to say that it works trouble-free for me. I'm using it to connect my 30-inch Cinema Display to a mid-2009 Mac Mini and I have not encountered any of the problems that have been reported by so many other users. No flicker, no lines, no static, no freezing -- just a nice, crisp, huge, high-res display.

    Only 4 stars, though because it costs so much and because Apple ought to consider the significant investment their loyal customers have made before changing display platforms again and again and again.
