    Works Great - Some tuning Required

    I just upgraded my PC to a MSI 7970 Video card and discovered to my dismay that it required a Dual DVI to Mini DP Adapter to push 2560x1600 resolutions to my sweet sweet 30 inch monitor. After reading the problems on these forums, I still felt that the device should work as advertised, so I gave it a shot.

    To my dismay, while it worked perfectly I do experience the distorted screen as many people have reported.

    However, after giving it some thought, and watching it's behavior for some time, I realized that the distortion only occurred everytime I left the room for extended periods. The only thing that kicks in at that time (Over an hour) was my power saving mode for the screen. Since turning off Power saving mode, i'm no longer experiencing the screen distortions as reported on these forums.

    Great Product, though it is quite expensive for a simple adapter.

    Works BUT

    I find it works perfectly on my Samsung SA850 from my MacBook AIr 2012. Only problem is when I reboot it goes fuzzy and needs plugged in/out to fix it - if left to sleep not an issue.

    Full resolution is possible on the SA850 with it. It works great. Very nice on this screen. I think this display for half the price of a cinema display is a much better deal.

    £70 is actually cheap stop moaning at Apple! They are probably selling this at cost. The third party ones out there are over £130. But I suspect they work on non apple monitors much better. I may try to source one of them but if you are stuck remember they exists and to go looking for them!

    Works for 30" Samsung Syncmaster

    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.

    Not with a Macbook Pro Retina

    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.

    works fine but too expensive

    Despite the endless series of negative reviews, I bought this to connect a Samsung 305T to my MacBook Pro 15" Early 2011, and it seems to be working just fine at 2560x1600 (not mirroring) for now. It is too expensive so I really can't give 5-stars.

    Hope my words could help hesitant people make their decision to buy this adapter for non-Apple displays.

    Bad cable could be the issue. Not 100%

    Noticing some of you have had flicker or other display issues with this adapter and I would like to add something that may or may not help.

    I to have had flicker or snowing effect or even a thin vertical line on the screen when using the adapter, but found out after using other cables I had stored away, short and long ones, that finally one DVI cable actually worked well with no issues.

    Just might be the case with you guys as well. It just might be a bad cable.

    Works well with Apple iPad 10W USB Power Adapter

    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.

    Works well with high-power USB port

    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 MacBook Pro, but surprised me a bit.

    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 enough.

    Connected successfully to my third party monitor (Samsung SyncMaster 220WM). Although, when display wakes up from its "sleep" the resolution is all wrong and cannot be changed; computer must be restarted to use correct resolution. Apple support could not help me resolve this issue so I disabled my sleep settings.

    If I don't let my displays sleep there is no problem. I prefer this solution (because of performance and price) to my easily breaking, Matrox multi-screen device.

    works as advertised

    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

    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.

    Works great..price too high

    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

    Works with Cintiq 21UX and iMac 27"

    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.

    Works wonderfully - IF it's got firmware version 1.02

    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.

    Works flawlessly! All the criticism is underserved

    I use the adapter to connect my 13" Macbook Pro (2.66 Ghz Core 2 duo) up to a 30" dell display, and I've had no issues whatsoever. I plugged it in a month ago, and have completely forgotten about the adapter.

    I use my computer for very intensive design work, with graphics-demanding CAD modeling and lots of Adobe creative suite, and have never had issues with lag. I also plug a 4 port USB hub into the adapter and all the ports work great.

    Now I have the awesome beauty of the 30" display with the convenience of a mini displayport. Let me just say, I don't miss screwing and unscrewing that DVI cable one bit.

    Firmware 1.03, i7 MBP

    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

    Avoid buy a second screen for my laptop

    A friend give me a 30" display, and I was not able to use it on my mac book pro, I called apple care support, and I the only response was i will able to use my screen, but after lots of search in forum, a blessed forumuer told me to try this cable.

    And you know what ? It work perfect. I'm now in 2560 x 1600 on my second screen !

    I really enjoy working in 30" from my 13" laptop ! If you have a 2560 x 1600 second screen you need it, and not need apple care call (without any useful answer and knowledge of apple product)!

    World of difference for Me

    I just got a Mac Mini and used my 28" LG monitor. Before using the Dual Link Adapter i had a slight grainy display. I read about this adapter and went over to my Apple store to discuss. The Apple gal told me it will help and if i was not happy, bring it back within 15 days.. After trying this out,, it is not going back. The Dual Link Adapter was like night and day, It provided instant improvement. My display is very vivid, crisp and sharp. A hundred bucks is a bit step but what else can you do? this is it!!! For me it was worth it,, I did not have any issues some of the folks talk about and i intended to use the IPod power adapter some of you talked about but i could not find a male to male USB cable,, Where are you guys/gals finding this cable.. I went about every where i could in Sacramento and could not find one. So far i dont need it but now im on a mission to find one. HELP.... Back to the Dual Link DVI Adapter,, It's awesome,, go get one.. It works awesome.. and if you find the male to male USB,, tell me where.
