    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.

    Expensive , but it works

    I was somewhat apprehensive about spending serious coin on an adapter after reading some rather negative reviews. All I can say is with my 2011 MBP and a 2004 30" Cinema HD Display it functions perfectly . Apple screen , Apple laptop , & Apple adaptor , perhaps that is why it works for me and not others ?

    As Advertised (except in mirror mode)

    Here's my configuration:

    Late 2011 15" MacBook Pro 2.2 GHz Intel Core i7 with 8 GB memory connected to a Dell 3007WFP.

    I now have 2560x1600 on my Dell 3007WFP! Mirror mode, however, only manages 1680x1050, so if you intend to use it this way, which I don't, you may be disappointed (or maybe I'm missing another setting somewhere).

    Otherwise, works exactly as expected. Would give it 5 stars if not for the mirror mode shortcoming.

    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.

    No problem with a Dell 3007 WFPHC

    Contrary to some of the reviews I've read about this adapter, I've had no problem using it between a MacBook Pro 2009 and a Dell 3007 WFPHC. I don't notice any flickering and I've haven't lost video.

    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 as advertised. No problems here.

    As I said in the title, it works exactly as I'd expect it to. I have a 27" iMac that I wanted to drive a secondary 30" Apple Cinema Display. I'm getting full resolution from both screens. 57" of work space and loving it. Absolutely no issues.

    A little less expensive for an adapter would have been nice. I also bought the regular MiniDisplay to DVI adapter first and Apple should call out the fact that those won't drive a 30" display a little more blatantly on the site.

    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 fine with MacBook 5,3

    I have the previous Gen Apple 24 Cinema HD display. This cable works for this setup. The laptop needs to be plugged in (not on battery). Occasional (once a month) flicker, but I just unplug the USB and plug it back in after about a second. Other than the occasional glitches, this cord delivers a very crisp picture and does not seem to affect refresh, pan or zoom.
