    Could be better

    • Written by from Coffs Harbour

    I have the latest version of this cable and it still has digital noise issues, as have the previous 2 versions. This happens when my external monitor sleeps and then wakes. Alternate monitors, makes and models all do exactly the same thing, as do alternate DVI Dual Link cables, so it's an ongoing problem in the cable firmware. The easy way around it is to prevent the external monitor from sleeping.

    Prominently displayed on the apple images for this device is a USB socket next to the DVI socket. I've not found any use for this, as connecting anything to this port fails to register on the Mac (Air, 2011). And again, this has been the case for two different cables. Apple could easily build in a usb hub or power connector from the DVI to make this product more useful.

    At this price the product is half the cost of a thunderbolt dock, which has significantly more options. I'l buy one of those next time.

    Not a matter of IF but WHEN it starts playing up

    • Written by from SCULLIN

    Horrendously expensive for what they are, and I've lost count of how many I've been through over the years. It seems inevitable that after a while you get intermittent flickering/noise appearing on the screen, to varying degrees. Lucky you if it happens while still under warranty, because Apple is great at replacing it no questions asked. But if outside of warranty, too bad, and not cheap to replace.

    Works as expected

    • Written by from Redlands

    I am using it with a 2012 Mac Mini and a 30" HP Monitor. Occasionally I will have to disconnect it but I think that maybe the HP monitor that is causing the issue.

    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.

    Terrible, buggy product.

    • Written by from Brooklyn

    I have an old 30" DELL monitor and have to use this by necessity. I've had it for about 5 years and it has never worked properly. There's constant light background noise on the screen, it sometimes glitches completely, and so on.

    If you can possibly avoid it, do not use this. Unfortunately, if you have a dual-link DVI monitor, you don't have much choice :(

    (and yes, I'm on firmware 1.03)

    Lots of green digital noise...

    • Written by from WILMINGTON

    Just upgraded to a new MacPro and Pegasus2 Raid drive, so after shelling out huge money for that setup I wanted to continue to use my 30" Apple Cinema Display and not have to buy another monitor. Bought this adapter thinking that would be easy enough but am very unsatisfied with the results. I get get constant green digital noise in any areas of black on my screen. It's pretty much constant and nothing seems to fix it. I'm sure it's not the monitor, since I can plug it back into my old Mac Pro tower and everything works fine. At $100 for the cable I'm very unhappy. Does anyone know of another way to still use my monitor? Is there an HDMI adapter that anyone can recommend?

    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.

    not as bad

    • Written by from Portland

    So I spent an hour trying to get this to work for a large display. and then noticed i was using the wrong DVI cable. My screen kept flickering when set to the highest resolution, but once I got the proper DVI cable, everything worked.

    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.

    Working well with a 30" NEC Display

    • Written by from Toronto

    My recent copy of this cable runs well connecting my 2013 iMac 27" and my 2008 NEC 30"" display.
    I have the USB plug connected directly to my iMac USB port.

    No negative issues.

    (Note, I have only been running it for 2 weeks, so I can't speak to longevity and have therefore not given 5 stars. Will report back later.)

    Some reviews speak of the USB ports of some Macs not providing this adapter enough power.

    In that case, an Apple level 2 tech confirmed that plugging the USB plug into an iPad charger connected to a wall outlet might help and would not hurt the adapter. Hope this helps those having this problem.

    Bad performance and ultimate failure.... TWICE!

    • Written by from Portland

    I love Apple products but this one is absolutely terrible. I have a 27" Crossover 27Q monitor and bought this cable when I bought my Late 2013 15" Retina MacBook Pro. I put up with random flickering and cut-outs (on average just a few a day...), but after 5 months it died. I then talked the manager of the local Apple Store to let me exchange it for a new one, which exhibited the same issues and died a mere 2 months later. I actually just ordered a new monitor that uses native display port to avoid this hassle. What went wrong with this product? Is the technology just fundamentally flawed or did Apple cheap out on this expensive adapter?

    Very uncharacteristic of Apple to let such low quality slide.

    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!

    Monitor doesn't wake up with the laptop

    • Written by from Etobicoke

    When I "wake up" the laptop the monitor doesn't come on. The adapter starts cycling as if it can't get enough power. If I unplug and replugin the USB for the adapter the monitor wakes up.

    Also, the device draws a *lot* of power, my late 2013 MBP can't power the adapter unless the MBP is plugged in.

    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.
