    Bad cable could be the issue. Not 100%

    • Written by from Dunedin

    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 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 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.

    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.

    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.

    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 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 enough.

    • Written by from Herriman

    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

    • Written by from Gilbert

    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

    • 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.

    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

    Works as advertised. No problems here.

    • Written by from Ottawa

    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"

    • 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.

    Works fine with MacBook 5,3

    • Written by from Washington

    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.

    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.

    Works flawlessly! All the criticism is underserved

    • Written by from Stanford

    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.

    Works perfectly w/MacBook Pro i7

    • Written by from Smithtown

    Just bought a new i7 Macbook Pro 17", and hooked up my 30 Cinema Display. Been using it for 2 days now, no problems of any kind, no flicker, no noise, it just plain works. Other than the extra wires, which I hate, and the 100 bucks that has to be spent because Apple is ramming this new Mini-video which no one else is using down our throats, I'm happy with it.

    Still think the new Macbook Pros should have DVI and more ports, like the pre-Unibody Macbook Pros. Anyways, if you're thinking about buying this to use with a new Macbook, don't hesitate.
