    Doesn't work

    • Written by from Rockford

    Plugged it in properly installed latest updates and this device doesn't work. My computer is also brand new. I bought two 30 inch displays with the screaming HD ATI graphics card, I was pretty excited to utilize two 30 inchers. But when I plugged in the 2nd monitor, the monitor never wakes from sleep mode. I even swapped monitors to see if I had a bad 2nd monitor. That wasn't the issue. I called Apple Support and they couldn't figure anything out. In fact, there was no technical notes for them on this device so they were in the dark. Also, there are no instructions when you receive this device. Just a warranty. For a while I just didn't know how to hook it up! I I'm actually going to return this device and the 2nd monitor and not bother with a dual set up... I don't have time for all this trouble shooting. I just want to buy it and have it work. Apple stuff is already commanding a high price and especially one that is not based on intrinsic worth it's beyond a prospective buyer's means most of the time ... so if it's pricey then it should work right? Come on get with it Apple! Don't be like GM!

    Firmware 1.03, i7 MBP

    • Written by from Hawthorne

    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

    • Written by from Le Cannet

    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)!

    Works Perfectly - Forget about the poor reviews

    • Written by from Scottsdale

    I have no clue why this device has gotten such poor reviews. Maybe the first-generation units had a defect or users were unclear as to exactly how/why this is supposed to be connected. (You need to make sure the USB connector is plugged into either a powered USB hub or your Mac.)

    I just purchased one on 4-5-10 connecting my 2.8Ghz MacBook Pro to my 30" inch ACD with ZERO issues whatsoever. No flickering, no lines, no color shift - it's *perfect*.

    It also works perfectly in BootCamp running Vista 64 and I use my 30" inch ACD as the primary monitor - even running Flight Simulator Acceleration and it's flawless!

    Get one and be happy.

    Beware!!!

    • Written by from New York

    I bought this to run my Dell 30" monitor from a brand new mac mini. I run the monitor at the full 2560x1600 resolution and need to plug the USB into an external power source through my iPhone charger. In short, the cable works perfectly about half of the time, and the other half of the time it is either:
    1) completely unusable, blurry across the entire screen or
    2) usable, but with flickering lines in the very dark areas of the screen.

    To fix the problem, I can either put the mini to sleep and immediately wake it, pull the USB cable from the charger, or restart snow leopard. It stops working sporadically in the middle of things and is VERY annoying.

    Apple please fix this!!! My previous macbook pro with a normal dual-link dvi connection worked perfectly and it is completely unacceptable to spend $100 on a adapter that doesn't work 100% of the time!

    I just don't get it!

    • Written by from Newport News

    I purchased this adapter to connect my MBP 13" 2.26 5,5 and a 30" Apple Cinema HD Display and it works perfectly! I never had an issue with a flickering screen, poor color rendering, vertical/horizontal lines or artifacts...it just works as advertised. Based on my experience it's gets 4 stars (reserving one because i think it should cost half of what it does).

    It's a driver issue

    • Written by from HILLSBORO

    I got this for my Samsung 305T. Although it displayed properly, the screen would continue to flash. It was never showing the screen for more than a few secondss before it would flash dark again. Totally unusable. I tried connecting the USB to a more powerful source but that didn't help.

    I measured the current drawn from the device from the USB port and it never drew more than 200 mA, which should be fine for most computers with USB ports. I don't see how that could be the issue.

    I partioned my mini mac for Windows XP and lo and behold. There are absolutely no issues when running the cable and monitor using XP on the same mini mac. This rules out the problem being the monitor, cable or mini mac. The problem is the Apple driver, either for the adapter or for the integrated video. Since it works on XP, I'll keep the cable. But I can see why there are so many complaints!

    World of difference for Me

    • Written by from LINCOLN

    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.

    What a Difference !

    • Written by from gaithersburg

    I am using my old 30" Dell 3007WFP monitor to my new 15" MacBook Pro. I started with the Single-Link DVI adapter and was terribly distressed with what the monitor was doing. I began to research single verses dual link and decided to go ahead and try this adapter. It has turned this old 30" diaplay into a new monitor. I am running it at 2560x1600 with unbelievable crispness. I have had no problems with either the adapter or the monitor since plugging it up. I strongly recommend this for anyone with a large display!

    Sometimes works

    • Written by from Sandy

    Expensive piece of hardware, but is amazingly flaky. I mean it works most of the time, but is subject to random problems is the form of messed up displays (get used to unplugging and plugging back in). It's a digital to digital converter but it produces artifacts that you would expect from a analog to digital converter.

    Seriously, can this not be done better?

    (yes I have the latest firmware)

    Horizontal lines on black areas

    • Written by from JOUTSA

    I have a mid-2009 MacBook Pro, 30" Cinema HD Display and adapter v.10.2, and suffer from the same errors on black areas as everybody else. The display is 4 years old and has worked perfectly until using this adapter.

    My worst Apple product ever

    • Written by from ITHACA

    The 30" Cinema Display shows static, is less sharp that the direct DVI used to
    be, and from time to time doesn't detect the proper resolution
    (messing up all window sizes and positions from sleep) -- for
    which the only solution is to go back to sleep, unplug it, re-plug
    and wake the MBP again. Even giving it its independent power through
    an USB hub doesn't help.

    I find it really disappointing that Apple won't find a solution for this,
    even after so many months.

    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.

    Using my Mac Mini with a Dell 3007WFP, running fast and fine at 2560x1600!

    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.
