    Working well with a 3rd party monitor (Hazro HZ27WC)

    • Written by from Sheffield

    I initially had issues with the well known interference (intermittent colour distortion and artefacts etc) which was pretty unusable.
    I was using a cheap DVI dual link cable that I had bought 6 years ago. So I bought a startech branded DVI dual link cable (£8) and now I have no issues at all, working perfectly. My monitor is a Hazro HZ27WC, with a late 2013 Macbook Pro 15".

    By the way, the same old cable I had works fine when connected to my PC with the same monitor, but doesn't work with the Apple adapter. My guess is that Apple's adapter has different and stricter time constraints on the digital signals perhaps and therefore requires a decent quality cable.

    So my advice is, don't listen to the people complaining about the adapter. Just try is with a decent quality DVI cable for yourself. When I say decent quality DVI cable, I don't mean spending £50 on one, you should be able to get one for under £15 online.

    A solution to the Flickers!

    • Written by from Chateauguay

    I looked everywhere for a solution… and found my problem on a Forum…

    There are two types of DVI cables!

    A) DVI-D single Link
    B) DVI-D Dual Link

    They don't have the same number of pins!

    I have a MacBook Air 13" 2011, with a 30" Dell Ultrasharp. With the single Link DVI Cable, I had crazy flickers.
    With the Dual Link cable - supplied by Dell with the Monitor, the image is EXCELLENT!

    It works: Mac mini (Late 2012) to 30 inch Cinema Display

    • Written by from Nashua

    I bought my Mini DisplayPort to Dual-Link DVI Adapter yesterday from an Apple Store and the unit works as advertised. It has revision 1.03 firmware, which is apparently the latest as of 2014-07-04 and thus saving me a return to the store for an upgrade/swap. The unit worked on the first try connecting an Apple Mac mini "Core i7" 2.3 (Late 2012) [MD388LL/A] to an Apple Cinema Display 30-Inch (Aluminum) [M9179LL/A]. There are no problems with dropouts or flicker. Sleep/wake also works, as does the USB connection.

    The adapter has no facility for connecting the monitor's 400 Mbps FireWire port, so if you have the same type of monitor, then you may need a FireWire extension cable -- if you want to use the FireWire port on the monitor.

    Interestingly, at the Apple Store, the adapter was not on the wall with the multitude of white box adapters on sale; the manager said that the store did not carry the item. However, another store employee fortuitously did know about the adapter (packaged in a black box) hidden in the back room and procured the prize. Who knows what other goodies may lurk in that nearly impenetrable darkness? Could there be a 20th Anniversary Macintosh concealed in the gloom? Maybe there's a unsold, Apple IIgs there waiting for some lucky collector. If such could be found, there might even be hope for locating an Apple Lisa which escaped that landfill in Utah.

    The adapter you need for high-resolution monitors

    • Written by from Boulder

    This is the adapter you need to connect a high resolution monitor (WQHD) to your Mac. (The regular Mini DisplayPort adapter will leave your monitor maxed out at 1080p, not the 2560x1440 you are after.)

    A couple of notes:

    * While this is a hot plug, sometimes the signal can get a glitch when you connect the monitor or wake your computer from sleep. I found that 95% of the time, simply turning the monitor off and on again addresses this. On rare occasions, it took a reboot of my computer.

    * You need to connect the USB plug on the adapter into your Mac as well, or you defeat the purpose of this adapter. The USB is necessary for the resolution. In fact, the old Apple 30" CinemaScreen monitors won't even display anything without the USB connection.

    Works flawlessly

    • Written by from Seattle

    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

    • Written by from Woodhaven

    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

    • Written by from Liskeard

    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!

    Worked Great

    • Written by from Avon Lake

    I used this to connect an older 30' Apple Cinema Display to a new MacBook Air. I was a bit surprised that the monitor would not turn on unless the USB cable was connected, but other than that it worked exactly as advertised. The display is running at its full resolution of 2560 x 1600 with no flicker. I did not need to restart or reconnect the monitor it worked fine the first time. I have only had this a week, but I use it all day every day at work and it has never had a problem. I see quite a few people posting with issues. Perhaps it does not work well with all monitors. With the Apple 30' Cinema Display it seems to work like a charm.

    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?

    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.

    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.

    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 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.
