    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

    • Written by from SAN FRANCISCO

    Using this device to connect my Cinema HD 30 to my brand Macbook Pro I get terrible static flicker. This occurs with or without the GPU turned on. I don't recommend this combination, or this adapter. This is poor execution on Apple's part

    Snow and Flickers

    • Written by from Huntington Beach

    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.

    How to run with Dell 30"

    • Written by from Dothan

    The is a comment from a gentleman in this thread that mentions the USB connection. That is the key. I have a 3 year old Dell 30" monitor that would not work with the adapter. I have noticed that none of these laptops have enough juice to power the USB devices on a chain of hard drives, etc. So I had purchased an AC adapter powered Tripplite USB hub. When I plug the USB cable from the Apple dual link adapter to the powered hub the adapter works fine so far.

    Summary: If you want it to work you need an AC adapter powered USB hub or similar device.

    Works most of the time.

    • Written by from Lincoln

    The other reviewers are correct -- you buy this cable not because it works well, but because it's your only choice to drive a 30" monitor. When my MacAir goes to sleep, there's significant chance it will wake up with random vibration rainbows all over the screen. The best workaround I've found is to select a different screen resolution (for example, 2048 x 1536, and then re-select 2560 x 1600. You have to re-size your windows, but at least nothing else is affected. Not, in short, Apple's finest hour.

    A great disappointment

    • Written by from Soquel

    I bought a 30" cinema display, and loved it. Then I bought a new MacBook Pro with the dreaded mini DisplayPort. No problem Apple has a converter box, right? WRONG.

    This is a terrible piece of junk. Any area of the display with a single dark color is plagued with noise. It wrecked my investment. Thanks for letting me down Apple.

    Screen blackouts

    After about a few minutes my screen goes beserk.
    the dual link to dvi adaptor is not only a waste of money, but also my 3000 dollars 30 inch cinema display is a complete waste.
    Worst is that apple has known this bug for a year and does not fix it.
    And im running it to a brand new 27 inch core i7 Imac.

    Vertical stripes and pixelated screen upon waking from MacMini 2.53

    • Written by from Bellevue

    I should have read the reviews here first, as I too am experiencing vertical banding upon waking up my 30" cinema display from sleep (usually overnight sleep only). I just purchased a new MacMini 2.53 (server model). I have not yet attempted to plug the USB adaptor into a powered USB Hub, as other have suggested. But this cable cost $100, and it should work plugged into the MacMini, unassisted.

    I was tempted to purchase the new 27" iMac, but I did not want to part with my 30" matte screen. It has to be the cable, as my 30" cinema display never exhibited this issue plugged into my MacPro (2 year old model). The cable is the only variable here.

    Just works

    • Written by from Albany Creek

    I have used this with my 17" MacBook Pro and with my new 27" iMac. Just plugged it in and worked. I am using it with a Dell 30" LCD. In both cases it just plugs in and works as I would expect. The Dell now displays in native resolution. The screen is not as good as the iMac screen but I do now have lots of screen real estate thanks to this device.
