    significant drop in frame rate

    • Written by from Austin

    Forget watching full-screen video at native 2560 x 1600; the framerate is 20FPS at best on my 2.53GHz BrickBook Pro.

    Also, the USB pass-through port does not seem to function.

    I give it two stars instead of one for actually existing, but overall, I'm ver dissappointed because apple didn't make this shortcoming apparent anywhere in their store, also, Apple needs to get on the ball and produce a 30" display that actually uses display port... seriously.

    Apple changes product description

    • Written by from Toronto

    This product description use to state this adapter would work for any monitor that required a dual-link dvi connection.

    After receiving multiple complaints, Apple has changed the description to include only their 30" cinema display instead of fixing the real issue.

    The adapter WILL work with my 30" Dell display, but I occasionally will experience issues (static, snow, etc) - only a reset (computer, display, settings, sleep) will bring it back. A serious nuisance.

    Bad Apple...

    • Written by from Lewes

    MBP + 30 inch ACD. As a Mac user for over 20 years this is the worst Apple product I've used. The picture quality generally is okay but on black I get horizontal flickering, which is simply unacceptable. As someone else remarked, I wouldn't mind paying the $99 if it worked but this is way below Apple's usual standards. Shameful.

    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!

    Firmware version 1.02 fixes the problem

    • Written by from Beaverton

    I bought this adapter 4 months ago for my MacBook aluminum (bought Jan 2009) and Dell 3007WFPHC 30" LCD. The adapter had firmware version 1.01 and had the same issues many users reported: intermittent flickering, color speckle noise, blurry text, and analog-like color "snow". I could fix issue temporarily by putting the display to sleep and waking it back up.

    Today I took the adapter back to an Apple retail store, where a manager gave me a new replacement that has firmware 1.02. The new unit has performed flawlessly over the past several hours. If you have problems and have firmware 1.01, see if a retail Apple Store will also give you a free replacement.

    Fyi, find your adapter's firmware version:
    Finder -> About This Mac... More Info... Hardware -> Graphics/Displays -> look for "Adapter Firmware Version: 1.xx"

    Rating: Start with 5 stars because firmware 1.02 works, minus one star because the adapter costs too much, then minus two more stars because Apple released the product without adequate testing, wasting hours of my time trying to get it to work and eventually driving around town to get a replacement. 5 - 1 - 2 equals 2 stars.

    New Macbook Pro and Display Connectors

    • Written by from Tempe

    I just bought a new Macbook Pro with the i7 chip. It's a screamer and works beautifully in almost every respect but the display connectors. My old Macbook Pro had a full size DVI connector that directly supported every display mode I needed out of the box. Now to support my 30" Apple Cinema display I need this clunky connector? Really? To top it all, I bought the mini display port to DVI only to discover it's DVI-D (single link) not DVI-I. Every VGA to DVI adapter in my school is DVI-I so I can't connect without another adapter! So in the end I'm going to have to buy 3 connectors: mini displayport to dual-link DVI, mini displayport to DVI and mini displayport to VGA. A total of $160. For a company that has a reputation of attention to detail, Apple failed on this one.

    Works, but flickers and dies unexpectedly

    • Written by from LaGrange

    I read all the bad reviews, but had to buy the adapter anyway -- when I upgraded from my old MacBook Pro to the new MBP with mini displayport, this adapter was the only way to get my 30" Dell monitor to work.

    I never had any problems plugging the DVI directly into my old MBP, the monitor was crystal clear and never had a single issue. Since using the adapter, there is a constant flicker of red, green and blue pixels that are hard to notice, but if you're looking at a very dark screen they're very apparent.

    The adapter will also just die at random times, displaying a distorted picture, vertical lines, or both. I'll have to completely disconnect and reconnect to get it running again.

    For $100, you'd think it would be made better. Very disappointing especially since it's the only way to get my MBP to work with my monitor.

    Adapter is unreliable ... lots of snow

    • Written by from Cary

    I have a Del U3011 display that I use at home and connect my 2009 Unibody via the display port to the display. The cheap DVI Display adapter would not let me get a resolution greater than 1680x1050 and so I sprung the $100 for the Dual-Link DVI adapter.

    It is a very poor quality device as I generally have to change resolutions to get the "snow" to disappear. When it is working its fine but its definitely not worth the $100. The display will also intermittently cut out (blank) for up to 20 seconds and then start working again. I know its not the monitor as I also use it for a Windows box and the Dell display works flawlessly with that system.

    I'm a big Apple fan but on this device they get a major thumbs down.

    MacBookPro and Dell U3011

    • Written by from Aptos

    This dual link adapter did not provide the 2560 x 1600 resolution capable on the Dell U3011. My MBP is a mid-2008 with Nvidia graphics card 9400M and 9600GT. Using the minidisplay port to HDMI I could achieve 1920 and using the minidisplay port to VGA I could achieve even higher resolution, but still short of about 400x550 -- ish.

    I am going to return this product. And try the minidisplay port to display port cord. Otherwise, I'll be sticking with the VGA adapter.

    Flickering problems!

    • Written by from Belmar

    I bought this adapter so I could plug my new unibody, 17-inch MacBook Pro to my 30-inch Cinema Display. The problem is that my monitor flickers unpredictably during use. I've had this Cinema Display for over a year, and it was hooked up to two other MacBook Pros. This problem only occurred after this adapter was used to hook up to my computer.

    It works, but...

    • Written by from Oakland

    I have it attached to my 30" Apple Cinema HD display. I don't get any flicker and the screen always comes up, but any areas of the screen that are completely black display a rapid faint flicker of horizontal lines (think film noise). It's subtle but definitely noticeable.

    I'm on the fence about returning it.

    Gives static/snow when waking from sleep mode

    • Written by from Whitby

    I decided to buy this adapter due to the fact that they updated its firmware to 1.03. Turns out it didn't fix anything. It still gives a static/snow distortion to the external display when waking up your computer from sleep mode.

    Snow on screen when waking up, sometimes

    • Written by from BERKELEY

    This product works fine 99.9% of the time with a new Mac Mini/Lion and a Dell U2711 monitor running at 2560x1440.

    The only problem is that when the Mac Mini I am using wakes up from sleep mode, sometimes I get a lot of colored video "snow" on the screen.

    I can remove this snow by power-cycling the monitor. (I am not certain the problem is due to the cable - it could also be the Mac Mini itself or the Dell U2711 monitor at 2560x1440 resolution.)

    I am using firmware version 1.03 of the cable.

    If someone has suggestions, or even a location for support for this, that would be helpful.

    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)

    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.

    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.

    Not the quality I'm used to from Apple.

    • Written by from Laval

    I'm a Mac fanboy and I promote Apple and it's quality products wherever I go and also write software for the Mac. Unfortunately I have to write a bad review for this one.

    My setup is Macbook 5,1 Unibody with a 30" Dell 3008WFP Monitor.
    mini-DVI to DualLink DVI cable with firmware 1.02.

    At first I thought it was my screen that was defective so I got an exchange from dell, since then I've exchanged this cable for the third time and still the quality is not what I am used to from Apple.

    The new cable works fine at maximum resolution for a couple of days but then I start seeing pixelation ( like snow on a old TV set without cable) in the bottom half of the screen soon followed by the whole screen becoming green and flashing back to normal colours at a rapid 60Hz. My guess is that this adaptor cable looses sync after a while.

    If I disconnect the screen itself from the adaptor and reconnect it, nothing changes the adaptor still flickers the screen image, but if I disconnect the adaptor from the mac book and reconnect it, the adaptor is good to go for a couple of hours before it starts behaving badly again.

    I've tested my screen on another computer and also tested the screen with a normal mini-DVI to DVI Cable, both situations worked flawlessly.

    Basically said, this adaptor is not stable at all.

    When it works, it's great. When not, it's annoying.

    • Written by from Chapel Hill

    I use this to connect my 11" Air to a 27" WQHD non-Apple monitor (I had tried HDMI and regular DVI adapters and couldn't get full resolution). Most of the time, the D-L DVI adapter works fine and the picture looks great.

    About 1/10 times if I wake up my monitor from sleep, it looks great for a second or two, but then overlays the entire displayed image with a weird static. You can still barely see the picture, but you wouldn't want to use it. To recover from this, I often have to unplug the adapter from my Air and try again, sometimes multiple times are required. Also, it uses up a USB port and the pass-through one it provides does not provide much power: a mouse works, but the USB->Ethernet adapter does NOT work, nor does the external superdrive.

    Failure when laptop goes to sleep

    I'm using this cable for connecting to matrox triplehead digital.Works fine, only when computer going to sleep resolution get sometimes corrupt. Disconnecting the cables and connect again solves the problem most of the time.
