    Works fine except when waking up

    • Written by from Newton

    Works just fine with my MacBook Pro much of the time, but has periods when it flakes out: sometimes after waking up from sleep I get a bunch of static on my display (NEC PA271W). Power cycling the monitor clears things up, but it is annoying. Fortunately my monitor also has a DisplayPort input so I've switched to using a mini to regular DisplayPort adapter (also much smaller, cheaper, and doesn't need a USB port). If you've got no other option besides dual-link DVI then this adapter works OK, but I'd go with other options first if you can.

    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.

    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.

    Mini Displayport to Dual-Link DVI gives static

    • Written by from Caguas

    I have a 2010 model 17" MBP with a Dell 30" monitor and the adapter causes static on the screen when the MBP is woken up from sleep. The problem is fixed by unplugging the adapter from the MBP then re-plugging, sometimes 2-3 times. MBP works fine with other monitors; monitor works fine with other computers (without adapter). Clearly a problem with this product.

    Replace Dual Link DVI Adapter

    • Written by from San Diego

    This has been driving me crazy for months.... I had streaks going across my 30'. I tried everything except replacing....

    It took a trip to the APple store and demanding a replacement.... they tried to say that this was not an issue with the cable but i just demanded an exchange after reading this thread.

    Replaced cable drives my 15' macbook pro with 30 monitor perfectly.

    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!

    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

    Kinda sort of works

    • Written by from Durham

    My work monitor is a 30" Apple monitor and so when I got my new 15" MBP, I went out and bought this cable. After about 2 mins, I noticed that there were random spots light (just like that old Window's Stars screen saver). After about 5 mins, the screen started flickering on and off. I did some research and found out that apparently, there are multiple versions of this product, and if you don't have Firmware 1.02, the problems are terrible. (You can find out your firmware in the System Profile.) So, I did a "Firmware upgrade", which for this product means returning it to the store and asking for a new. The problems are *mostly* gone (the random spots of light are gone, but the screen will still flicker after the computer has woken up). Still, what I would consider to be unacceptable for a $2,000 laptop, $2,000 monitor, and $100 cable.

    This product is defective?

    • Written by from Vancouver

    I'm seem to have all the problems that others reported here with the Adapter creating "snow" signals and "interference" after using it for random intervals. The only way to resolve it is to unplug and plug in the DVI cable connected to my 30" Dell screen, so I often find myself unplugging and plugging in the DVI cables about a dozen times a day, which is seriously annoying me. This seems like a defective product, and I'm surprised that Apple is allowed to keep selling it.

    Prepare to be frustrated

    • Written by from SANDY

    You could almost excuse the ridiculous size and cost of this adapter if it worked properly.

    Using the Dual-Link DVI adapter with my 15" MacBook Pro and 30" Cinema Display is very inconsistent; while in-use the display will suddenly become distorted requiring that the USB and Mini DisplayPort cables be disconnected and re-connected. This problem is increasing in frequency over time.

    The computer will wake from sleep about 50% of the time without having to perform the same disconnect/connect sequence.

    In my opinion, the adapter is currently a terrible product - I'm (probably foolishly) optimistic that a firmware update will be released to resolve, or at least improve these problems.

    Was quite skeptical

    • Written by from Foster City

    Was very nervous because of all the bad reviews for an overpriced adaptor, but I needed one to power my 3008WFP, but it works absolutely perfectly with my 2.4GHZ aluminum macbook. Have not seen a single glitch and I am very particular about my displays. Gaming even is OK too (World of Goo and whatnot)

    It's not the $100 adapter, it's your $2700 computer

    • Written by from Redondo Beach

    I have both a MacBook Pro and a MacBook. The adapter works great on the MacBook and lousy on the MacBook Pro.
    On the MBP it flickers and loses sync on a regular basis.

    Also consider that it uses a USB port for power. Granted, there is a pass through port on it, but that can't even run a keyboard/mouse.

    I don't know what Apple's said (can't find anything), but I've read that the problem could be the USB power regulation. Meaning mainboard. Meaning good luck getting that fixed.

    Still, it's better than a PC any day!

    Failure when laptop goes to sleep

    • Written by from Heemskerk

    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.
    When it works it's great, but it looks like the os got some bugs with this adapter.

    $99 broken cable

    • Written by from SAN FRANCISCO

    This will be the last time I'm a first generation adopter of Apple's products. After waiting for over 2 months for this adapter, I discover that 8 out of 10 times, it doesn't work. The other times, my monitor flickers a few times before my Macbook gives me one resolution option of 640x480 on a 30" monitor.

    Static mess

    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.

    Connected to my Dell 30" U3011

    • Written by from SAINT LOUIS

    I reluctantly purchased the Dual-Link DVI to MDP adapter after reading the horrible reviews on this site and elsewhere. Yes, $100 to get full resolution seems excessive.

    I was able to get my 30" Dell hooked up and working properly. It works about 90% of the time, as I have multiple computers connected to the monitor, and sometime 1/10, when I switch the source input to my MBP, I see snow on top of my Mac OS screen. This is usually fixed by changing the input source to a different PC, then switching back to the MBP, or unplugging/replugging the MDP.

    For $100 it should work 100% of the time. 3.5 stars in my book.

    If you don't need USB pass through, you can pick up a cheap MDP to DP adapter from Monoprice
