    USB3 Please

    • Written by from Berryton

    I'd love to use this as a mini dock for my Macbook Air. I can put my Air in the stand, plug in power, usb3, display and have all of my USB devices and monitors attached via this adapter and a usb3 hub.

    (this would suffice until the thunderbolt docks are released...)

    Works wonderfully - IF it's got firmware version 1.02

    • Written by from Ferndale

    I bought this product yesterday and was disappointed that it caused a lot of red/green video noise with a 30" Apple display. It was the same with 2 different MacBook Pros (both unibody - one Core i7, one Core 2 Duo) and System Profiler showed that this brand new adapter came with obsolete firmware version 1.01 installed.

    After trying several suggestions in the Apple discussion forums, including rerouting video cables away from sources of electrical noise, using a separate USB "wall wart" power supply, and even wrapping the video adapter with aluminum foil to shield it from noise, I gave up and returned it to the other local Apple store (it's closer to my house) where it was cheerfully exchanged.

    From the packaging, it's impossible to tell which firmware version is on the hardware inside the box. Though the store manager was a bit reluctant to let me open the adapter to check the firmware version in-store, he said I could exchange it again if there was any problem.

    Fortunately, with the new adapter the video quality was immediately better. There were no green and red dots dancing all over my screen and firmware version 1.02 showed in System Profiler.

    Steve Jobs, if you read these reviews, it would be helpful if you had one of your Quality Managers work to get all of the old stock out of your stores. As an Apple shareholder I am concerned at the number of problems people are having with this device. One of the highest ranking reviews online calls this "The Worst Apple Product Ever?" and the store manager who helped me with my return could only say "wow!" when he searched for a way to update the firmware.

    This is a good product that would be great if it didn't come with "known buggy" firmware installed. At theminimum there should be a way to update the firmware, but neither Software Update nor a search of the Apple Support Forums / Knowledge Base yielded any results.

    Not with a Macbook Pro Retina

    • Written by from Saint Petersburg

    I bought this to use with my Macbook Pro Retina laptop and found that it only provides DVI-D Single Link - not Dual Link - output. My 30" Dell 3007WFP display requires DVI-D Dual Link in order to display its native 2560x1600 resolution. With this adapter, I can only use the display at a resolution of 1280x800. Others have reported getting Dual Link output from systems like the Macbook Air, so it seems like the problem is with the MBP Retina, not necessarily with this product.

    New firmware fixes the problem!

    • Written by from New York

    i had first gen of this adaptor and was also plagued by pixel noise and streaking. (I have a 2009 mac mini.) There is a new version of the adaptor with a firmware update (1.02) that fixes the problem! Apple techs in the stores do NOT know about this, you have to insist, but you will get a free replacement. AFAIK, there is no way to check firmware version from the box, you have to plug it in and look in System Profiler.

    Adapter works as long as updated model

    • Written by from Wichita

    This adapter works fine, I have a 30" Cinema Display running. I think most of the negative comments result from the earlier model which has an outdated bios version. If you do purchase from other source, make sure it is the latest model production. Wish adapter supported firewire is my only criticism.

    Works well with MacBook Pro, but surprised me a bit.

    • Written by from Folsom

    Because I work with both Mac and PC, needed to hook-up a Dell RazorSharp U2711 Monitor to my MacBook Pro. Found out *after* I bought the monitor that I needed this adaptor if I wanted to access the monitor's full 2560x1440 resolution (that was after the AppleCare rep told me I needed to upgrade my RAM from 4GB to 8GB, which I questioned and he found out to be wrong). I bought and hooked up the adaptor, but was surprised to find out that I was *required* to also hook up the USB plug, as this apparently provides the extra power to handle the dual-link hi-res display. Without the USB plugged in, no go. Also, needed to change out a Single-Link DVI-D cable to a Dual-Link DVI-D (didn't work without it). It now works fine, but I sure would prefer an Apple LCD Display. The Cinema Display's lack of ports and exclusive use of the MiniDisplay Port cable prevents me from hooking it up to a PC via a reasonably-priced KVM switch.

    Works for 30" Samsung Syncmaster

    • Written by from Waukesha

    I have been using the $99 dual-link adapter for about 8 hours, and all is well. The price is rather painful, but as long as it works, I won't whine too much.

    I wish I didn't have to contact my local Apple store to figure out that I needed this product. It would have been nice for this info to be more apparent for us large-display users.

    After making the connection, I rebooted my system. Strangely, it took a few minutes to boot my new Mini Mac. For the three previous days I had been using the new Mini (tolerating the fuzzy/jaggy screen image), booting had been swift. So the long boot-time had me fearing the new connection wasn't going to work. Big sigh of relief when it did!

    To reiterate what others have posted here: This review is for the special DUAL (meaning two connections) link adapter. In my case, it takes the DVI and USB connections off my Syncmaster display and converts them into thunderbolt and USB connections for the Mac Mini.

    Works well with high-power USB port

    • Written by from Palo Alto

    I've had this for a while and had the same trouble many people mention. It doesn't work at all without the USB connector. Moreover, it really wants a high power USB port such as found on macbooks. I think this is why so many people have varying success. If you plug it into a hub, you'll get anywhere from nothing to sparkles. The macbook USBs have higher power (as needed by iOS devices). If you use the AC USB adapter that comes with an iOS device, I think you'll have far better results.

    Works well with Apple iPad 10W USB Power Adapter

    • Written by

    TL;DR: If you want to use this, you really need to use the Apple iPad 10W USB Power Adapter to power it.

    This is an update to an earlier review.

    This thing (evidently) requires a lot of power. Fairly recent Macbooks shuld be able to power it, though generally only if you aren't using the other USB connectors and, in particular, if you don't plug in an iPhone, iPod Touch, or iPad (particularly an iPad). I've tried using an external powered hub, the AC adapter that comes with an iPhone, and the adapter that comes with the iPad. The 10W iPad charger is the only thing that results in no connection problems or sparkles. With the 10W connector, it's absolutlely solid. Clearly, they should have inlcluded it and told people not to try it without it. The way the USB connectors on a Macbook work, you'll get various results not only depending on what else you plug in, but the order in which you plug them in.

    Apple would have saved themselves a world of hurt if they'd just included the 10W connector.

    A little bulky, but works fine

    • Written by

    Plug-and-play functionality on a Matrox Triplehead2go 3840x1024 at 60hz. The USB port on the Dual-Link adapter didn't have enough power for the Matrox though, so I had to plug directly into the laptop.

    Firmware 1.03, i7 MBP

    • Written by from Hawthorne

    Just got the Core i7 15" MBP and the adapter from a store. It has firmware v. 1.03 on it. Completely plug and play... No glitches, no unplugging, don't have to plug in to external power... operating on my 30" Cinema Display without issue. At work, I have a 1.01 adapter and a Matrox TripleHead2Go DVI (Digital) edition. That's a bit of a different story, but it's not supported by Matrox, so I can't really complain. The good thing is, that I have that one working as well to drive 2 1600x1200 monitors.

    4 stars because it's really freaking expensive and Mini Display Port, I feel, is completely unnecessary

    Works after swap

    • Written by from Pittsburgh

    Returned my old Adapter with 1.02 firmware for a new one with 1.03 at local Apple Store (no charge) and my digital noise problem is a thing of the past. If you have one with firmware below 1.03 take it back and get a new one.

    works as advertised

    • Written by from Tucson

    I've had this adapter for about 2 weeks now. Contrary to what its name implies, it does NOT allow you to use it to drive two displays, though that's what I am doing with it by means of a second piece of hardware: Matrox TripleHead2Go Digital. Every time you attach two active adapters together, problems are bound to follow, and I do have problems waking my displays from sleep (I need to power-cycle the Matrox box to do that). Still, for an unsupported configuration, it works quite well.

    My adapter has firmware 1.3. People around here complain it does not solve the problems with firmwares 1.1 and 1.2, but that has not been my experience: I do not see noise in black areas. I do not see distorted graphics. I do not see odd lines on my displays. Neither of these is also a problem when I run QuickTime or iTunes. Pixel-wise I am driving slightly more pixels than what your average 30" display has, so I am pushing this adapter close to its limits.

    My complains are the following: (1) compatibility with my video extender (I wish). (2) price: this is effectively a $80 fine for running decent graphics! (3) design requiring this adapter be powered through a USB port on your laptop: show of hands, how many people enjoy being able to cook eggs on their keyboard? (4) USB port on the face of the adapter is drained of virtually all power, so nothing works off it.

    Works for nVidia 3D Vision

    • Written by from Woodland Hills

    Using this Dual-Link DVI adapter with my 2010 Macbook Pro (Core i7 + nVidia GT 330M) allowed me to use nVidia 3D Vision under boot camp with Windows 7. The regular DVI adapter is only capable of 60hz output, but under boot camp this adapter will allow a 120hz output from the GT 330M thus letting 3D Vision work. I primarily need 3D Vision in order to view stereoscopic visual effects footage for work and was thrilled to discover I could do this with my existing Macbook Pro. I'm using the Asus VG236H monitor and it works perfectly. I also fired up Portal just to see if it would work in 3D vision and to my amazement it ran well in 3D even under fairly high settings despite the fact that nVidia's system requirements state you can't do this.

    Unfortunately, I have to deduct a star as I'm unable to output 120hz to my Asus display under Mac OS X with this adapter. It shows options up to 75hz but they are all greyed out and the only mode I can use is 60hz under OS X. Windows 7 will allow you to use the full 120hz.

    Pricey but does the job fine

    • Written by from Chicago

    It is pricey, and honestly it is one of the things that help me off from buying a new macbook pro. Unlike some of the people here that have had issues though, I am using this with a new 15" macbook pro i7 and a Dell 3007WFP-HC 30" monitor for the last week and have not had any issues. No flickering, needing to restart, etc. I am also not a fan of this taking up another usb port, but if you use a good powered usb hub, it isn't really an issue. i don't see many alternatives for this and it works fine for me.

    Works well with a good cable (2012 15" Retina MBP)

    • Written by from Ballston Lake

    I bought this too hook my MBP up to a Yamakasi Catleap monitor. Works great with very few issues. Once in awhile after waking from sleep, the monitor will have static in the picture, but if I just turn it off and on, it goes away. Extended use does not yield any sort of issues.

    It is a little expensive, but most dual link dvi->mini display cables are. The relocated USB port is actually convenient for plugging my VPN token in, as it ends up right in front of me on my desk.

    Works with Cintiq 21UX and iMac 27"

    • Written by from Los Angeles

    Don't make the mistake of buying the Single Link DVI-D to Mini display port version for $30 like I did you need this $100 Dual-Link version to connect a Cintiq a to a mini display port it's even recommended in the wacom hardware manual the cheaper cable will give lots of random pixels flickering while painting.

    Four stars nothing wrong with it, apart from being over priced.

    Pleasantly surprised

    • Written by from Chicago

    For once, I am going to be in the minority here voicing concerns for what seems to be a flakey product. (Trust me, I've had the worst luck with hardware in the past) Let me say, I haven't had one single issue with it yet. I waited a few weeks before writing this review to make sure it was working properly.

    I had just bought a used 30" ACD off an auction site for a steal of a price to use with my Late 2008 model Macbook Pro. I expected to just buy the minidisplay port adapter from Apple and all would be well...that is until I read the horrendous reviews on this site. I'm a web designer, so display, colors etc. would be at the utmost importance for me. I was really hesitant to even go further, but since my monitor purchase wasn't made in store, I had no choice but to forge ahead, I went ahead and bought this adapter in-store the week of the July 4th holiday.

    It took me a while to figure out to get this to work in clamshell mode with the proper resolution (I defaulted to mirroring but that made no sense to me), but after that everything has worked flawlessly. If my laptop goes to sleep and I wake it up with a mouse, my display restores itself perfectly unlike what I've read in some of the previous reviews. Also, if your laptop is already turned off, all you need to do is plug in the adapter first, open the laptop lid and press the power button. Quickly close the lid and it should show up on your 30" display.

    Perhaps I got lucky? FYI, I got the 1.02 firmware adapter so like someone recently mentioned, perhaps those work a little better. Not a 5 star review since the price is a tad on the high side. Good luck everyone.

    Works great..price too high

    • Written by from Manchester

    I was nervous about buying this adapter after reading all the bad reviews before hand. I went for it anyway, and it works great. Using a Dell 30" 3007WFPHC monitor, with no picture problems at all. It's as sharp as anything.

    Please ensure you have a DUAL LINK DVI cable...not a normal DVI cable as the adapter then causes problems. I didn't realise the first time round when I plugged in my normal DVI cable.... just make sure it is a DUAL LINK version.

    Too pricey... for what it is. Hence the 4 stars

    ah.....

    • Written by from Bradford

    I was just about to curse my apple store having read these reviews and bought one to use with my HP LP3065 screen...and of course it came up as a jibberish screen.

    Fortunately I also have my PC hooked into the same monitor and decided to check the cable I was using for it to hook up and get its 2560x1600 res, it was different ....oops I had totally forgotten that I needed a duallink cable as well as the adapter.....a quick swap over and it works fine now. I don't think everyone here will have made the same mistake but its possible some will so I hope this helps.

    Anyway..as far as a review goes, it does its job well enough now that I have the correct cable, but I'm not mad keen on the hanging out the back concept here, would surely have been easier to have a duallink dvi on the unit itself?
