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

    • Written by from Portland

    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

    • Written by from Torrance

    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?

    Superb on Brand New Mac Mini 6,2

    It works as advertised for me, I'm running a brand new Mac Mini (purchased from apple.com on 2/2014) with an HP LP3065. The only USB device I have plugged in, however, is the USB plug from this adapter.

    Flickering Me Too

    • Written by from Albuquerque

    I've had one of these a week shy of a year now. From the get-go it would flicker.

    Well a few days ago immediately after one of these flicker events my MacBook Pro Retina shut down. It would only boot after a reset of the SMC, then a safe boot then a normal boot. After this event as soon as I would connect this, or any adapter to my MBP it would either shut down or kernel panic. I tried with different adapters, different displays, different keyboards, different everything. I reinstalled the OS too.

    So off to Apple goes my MBP for hardware repair due to damage brought about by this adapter.

    Meanwhile since I can't be without a laptop I purchased another MBP and another of these adapters. Within a day this replacement pathetic adapter started to flicker too.

    My experience is like so many others - this thing is worse than junk.

    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.

    you need to plug the USB cable in.

    • Written by from Boxford

    like most of you, i assume, i just plugged it into my new mac mini and plugged my older DVI equipped 23" Cinema Display. it didn't work. i unplugged it, and played around with it for awhile. when i plugged the USB end into the mini, the display immediately came on. it had not occurred to me that this widget, to support the Dual Link DVI standard, needed to be powered. you can plug the USB tail from the monitor into the widget, but that does not seem to be necessary.

    it seems to work fine. i have not tested it with non-apple displays.

    i assume that the manual mentions plugging the USB in, but i notice a lot of reviews that seem to imply it doesn't work at all, and i decided to put this out there.

    Unbelievable that they continue to sell this. Loses connection with the display every 10-15 minutes. Flickers. Absolute garbage - be prepared to return it.

    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.

    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!)

    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.

    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.

    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.
