    Works as of February 2010

    • Written by from Mountain View

    I've been using this adapter for a week with my HP LP3065 30" monitor and it has been trouble-free. No flickering or other display issues.

    My gripe is that the adapter should come with a USB patch cable at this price. The adapter consumes power through its USB connector and doesn't leave much current to power other devices from its output. So, I would have to patch the adapter's output to my monitor, or some other powered USB hub, in order to plug in only one USB cable when I set up my MacBook at my desk. For now I'm just using the other USB port on my MacBook in addition to the one used by the adapter.

    Not a big deal but $99 is already plainly expensive.

    Works perfectly with power

    • Written by from Seattle

    This is a fantastic product. Ignore everybody who gives it 1 star and insists it doesn't work: They're using it wrong!

    Dual Link requires more power to transfer its data than the mini display port can provide. That's why this has a USB dongle: Plug it into a self powered USB hub, which will give the USB connection all the power that the monitor needs, and it works great! It makes more sense than requiring that the adapter also have a plug that goes into the wall.

    Woe is me

    • Written by from Palo Alto

    Just like everyone else ... it's bad enough to pay $100 for a cable, but then it's really bad when it gives you white static lines across areas of the screen that are black. To make it worse, I bought two of them.

    iScrewed again

    • Written by from KAILUA

    I bought these cables because I had to if I wanted my new Unibody MacPros to drive my great old 30" HD Cinema displays. Doesn't work work at all. (Hmm, maybe they want to force me to dump my perfectly good display and buy a new $3000 display. How green is that!) I buy tons of high end Mac equipment, at least they could provide some support on what is obviously a high end problem. When you guys screww up you do it well. Apple - Take your (eye)Fingers out of your (eye)Aces and give your core customers some decent support on this issue. And DO IT NOW! (Expletives and the letter (I) removed to appease the filters)

    Terrible

    • Written by from Vancouver

    I am getting all of the same issues as the other commenters. My Dell 3007WFP which works fine with my old Macbook Pro is as good as unusable with my new MacBook Pro thanks to this adapter. Every 30 minutes or so the display gets these lines and the white static is nearly continual and especially noticeable when watching a video or editing text on a black background. None of the tricks suggested (such as using a USB hub) make a bit of difference and the Apple Store staff refuse to acknowledge the problem to the extent that I am considering hauling my 30 inch monitor into the store and showing them.

    Terrible

    • Written by from East Windsor

    I purchased this cable to run my 30" screen from my new 27" iMac.

    As an 18 year user of Apple/Mac products this is by far the worst one I've ever purchased. The static lines in black areas of the screen on the 30" are annoying and distracting to say the least. If you have the time to disconnect and reconnect the cable and power on/off the monitor... yes, you will eventually get it to where it does go away. The question is... who has time for that?

    This has also been an issue for such a long time I'm floored that it has not been addressed! Can it really be that difficult? Why would you leave DVI connectors for this abomination? Looks like they really jumped the gun on the whole mini-disply port connection.

    Works Great!!! Just try it!!!

    • Written by from Atlanta

    Many of the online reviews for this adapter are negative. I hope to dispel some of these rumors with this review. The Apple Mini Display Port to Dual-Link DVI adapter works flawlessly for me.

    I have a new Samsung T240HD 24" Widescreen LCD Monitor that I bought specifically to use with my 13" Macbook running Leopard. I researched both the monitor and this adapter before making either purchase. I'm not happy that the adapter was $99, but I am very very happy with results.

    Without any configuration, I plugged the adapter into my laptop and attached the DVI cable that came with my monitor. After pressing the power button on my laptop, I immediately close the cover and presto!! I have a 24" monitor. The monitor goes to sleep at the specified time and always wakes up when I move my Bluetooth Logitech MX revolution mouse (with the USB receiver plugged into the ADC adapter's aux USB port) or press a key on my wireless Bluetooth Apple keyboard.

    I couldn't have asked for better.

    Works well, limited data communication to NEC MultiSync LCD3090WQXi SV

    • Written by from reston

    I use this adapter to hook an NEC Multisync LCD3090WQi SV to my 13" Macbook Pro (June 2009 edition). This monitor includes SpectraView software and an xRite Calibrtion sensor to perform color correction by changing the contents of the LUT in the monitor. For this setup to work, the software has to be able to communicate with the monitor using the DDC, a data channel that's a standard part of the DVI specification. This communication is not possible using Apple's dual-link connector box.

    So in order to calibrate this monitor, you have to buy a single link DVI adapter, hook up your monitor, perform the calibration, then switch back to the dual link adapter to get the full 2560 x 1600 resolution. It seems silly that Apple overlooked the need to make DDC work correctly; this monitor is quite popular with Graphics professionals, it seems hard to imagine it was not tested with this adapter.

    Other than the frustration of having to keep another $30 adapter around and having to switch back and forth every 2 weeks to re-calibrate, this adapter works as advertised.

    Works Perfectly! Awesome Display on my 30" HP LP3065

    • Written by from Brooklyn

    This Dual-Link DVI adapter works perfectly -- provided you supply it with adequate power (1A) via the usb plug on this adapter's cable. To ensure adequate power, you are seriously encouraged to buy the Apple USB Power Adapter ($29) with this (it should really be included in the box with this adapter :-( ). Yes, it is an additional $29, but you won't be disappointed with the results!

    The other reviewers had bad experiences because their Macs did not supply enough power to this adapter via their native/built-in USB ports. Bypass those issues and buy the correct power adapter and enjoy Dual-Link DVI excellence at 2560x1600!

    Flaky at best

    • Written by from Peekskill

    I was so excited to get my new 17" MacBook Pro until I realized that this "Pro" product didn't work with my 30" Cinema Display anymore without me dropping another $100. I then get the adaptor to find that it is really flaky, my screen flickers few times an hour and it just seems like the whole thing was an afterthought at best. Really, really disappointed that Apple did this to their core audience who spends the most money on their products.

    Flicker = Power Issue

    • Written by from SEATTLE

    Great intentions for this apparently quick fix solution. Yeah, for what is rare to happen, Apple botched a bit on this extension. I can't complain in the end though because at least it works as desired.

    USB on almost every class of machine have the tendency to have power related issues. Devices that have a separate power adapter don't have to rely on this voltage. Bus powered devices are all trying to pull the voltage they need. In this case v1.02. If for any reason you get power fluctuations, your monitor will flicker, have issues, or not work at all.

    The Fix, plug the USB cable that is on the Y with the Mini DisplayPort and plug it into an external powered USB Hub that has its own power adapter.

    Don't have a powered USB Hub? No problem. Try using the 2nd Monitor's built in USB Hub. Plug the USB from the Y and plug it into your iMac and then take the USB out from the Mini DisplayPort to Dual-Link DVI Adapter and using a iPod/iPhone power cable and plug it into a Wall outlet for AC.

    Not sure any other way of doing it is worth it. Still glad I got it because there isn't really a better solution out there at this time.

    Worked fine, but expensive

    • Written by from Madison

    I had none of the distortion/flickering issues on my Dell 30" that others have reported; the adapter worked as advertised (even with the 1.01 firmware). $100 is too expensive for a simple graphics adapter, though. Also, they really should indicate better that you need to plug in the USB cable to get the thing to work.

    It worked perfect for me. Just Like it was designed.

    • Written by from Houston

    I used the cable to connect my 13" MacBook Pro to my 50" LG TV. The cable connected to my MacBook Pro correctly then I used a DVI to HDMI cable to connect the Apple cable so I was able to use the HDMI port on my LG TV. From there I just the Mac's systems preferences to clone the display. The picture was wonderful and I did not experience any of the issues like some of the other reviewers.

    Found solution for Mac Pro 4,1

    • Written by from Las Vegas

    I just bought this adapter to run two 30" Apple displays on a 2009 Mac Pro with GT120 video. At first I could get nothing from the mini display port using this adapter. But from reading the other comments regarding usb power, I tried connecting both the usb connector from the adapter and the usb connector from the display directly to the back of the Mac Pro (rather than connecting the display usb cable to the adapter case). That brought both displays to life in full resolution. Only been running a few minutes but seems good. Agree this is a very disappointing product, and as a very big purchaser going all the way back to Lisa (1983) I expect better of Apple.

    It's just a cable that does what it's supposed to

    • Written by from Towson

    Not sure why so many reviewers are blaming a wire for the fact that their computer can't connect with an external monitor. The cable is perfect and lets me add a 30in monitor to my new iMac. Don't blame the wire. The wire does just what it's supposed to do. if you use it for what it's not supposed to do, well, it's not the cable's fault.

    Dark areas of the screen full of noise.

    • Written by from Moreno Valley

    New unibody Macbook Pro. Older 30" cinema display.

    The only way to connect the two and run at native resolution 2560x1600 is to use this adaptor. But in any areas on the screen that are close to black there is random red / green / blue static noise. It is maddening. Especially when using any of the Apple Pro apps (Final Cut Studio etc.) which all have dark, dark interfaces.

    Apple are sending a replacement cable but with all the reviews on here I do not hold out much hope.

    $10,000 dollars of Apple hardware and software ruined by an overpriced cable that does not work to spec.

    Bad Flicker

    Snow and Flickers

    I depend on my mac and 30" monitor for making a living. I have a brand new macbook pro and 30" monitor. This adapter causes fickering and snow several times a day, sometimes requiring me to put the mac to sleep and wake up to fix it. Unacceptable!!! Apple needs to fix this!!!

    Purchased Mini DisplayuPort to Dual-Link DVI Adapter

    • Written by from Mississauga

    Read these reviews but I have a Dell 30", Dell 24" and Samsung 22" (all of which work fine on

    1) Screen flickers once in a while (tolerable) but diappointing.
    2) Now when coming back from sleep, screen messed up.
    Have to reboot to fix which is particularly irritating as I have many apps open.

    Apple PowerBook 13.3" 10.6 bought dec 2009.
    1.02 Firmware on adapter.

    Overall ... very very disappointing.
