    unreliable, way overpriced

    • Written by from Boulder

    Non-stop problems, as others have experienced, with snowy screen and flickering, especially when coming out of sleep mode using this adapter and a Dell U2711. Found a mini displayport to displayport cable that works flawlessly for a fraction of the price.

    OMG...!

    • Written by from Fort Myers

    Okay...Here it comes:
    This is the worst disappointment of all time.
    The Dual-Link DVI Adapter is an absolute failure by Apple in my opinion.
    Being quite the Apple nerd, I was certain that I could get it to work....NO...!
    It didn't work....I faced a barrage of problems: Screen flicker, video drop-outs, noise.. Finally just nothing at all. ZERO. Why Apple would take away a perfectly good DVI port on their MBP, and put this pathetic low-power mini-display port in, is beyond my understanding. The DVI port worked perfectly...PERFECTLY...I could EASILY drive the 30-inch monitor from my "old" MBP. Then..I buy a brand new MBP (with a mini display port) and it's a step BACKWARDS. Shame on you, Apple. You must have KNOWN that this wasn't going to work...why in the world would you EVER sell a band-aid for a hundred dollars...? You can drive a 23" inch monitor fine...by using the mini-diplay to DVI pig-tail plug. No prob. But I hope no one else goes through what I did. Tearing out an entire system out of office furniture...wires and plugs, etc..to put this thing in...all excited about a big, rich 30" screen. Now I have to tear it all out, and go back to 23"... Sorry Apple...this ranks worse than the reception problems on your iPhone 4....which I also own...when did it become okay to do this to your customers...? You are suppose to be different from all the others. Now it seems you're cutting corners....sad.

    Flicker, flicker, flicker.

    • Written by from Chêne-Bougeries

    I have read all these reviews and decided to give it a try (I have Samsung Syncmaster 305T+ 30" display). People at Apple Store told me if I got any problems with the adapter, I can get my money back. At first, it worked more or less OK (the image was scrambled occasionally, but turning display off and back on via Hot Corners solved the issue). Then, Snow Leopard graphics update happened few days ago (or was it the EFI update?), and it started to FLICKER. Several times per day, for 20-30 minutes. That drives me completely mad; I having headaches, and if I had epilepsy, I would immediately got a seizure. This is insane, and if Geneva Apple Store doesn't solve the problem, I will do something awful, I swear. I need my 30" display, I can't work without it.

    Flickers with 30" Cinema Display

    • Written by from San Francisco

    I just went to the Apple store to swap out this cable due to flickering (the service there was great). Unfortunately, the swap didn't help. Unfortunately for me, this means I need to buy a new monitor if I want the flickering to stop. (From a troubleshooting standpoint, the monitor works fine with a direct DVI connection, and I've plugged 3 different laptops in with the same results, so I'm confident the issue is with the cable.)

    1.3 is garbage too!

    • Written by from Parker

    I just went to the Apple Store, had them open the package and connect it to a computer to confirm the latest firmware 1.3 before I left the store. The Apple Store employee told me that they would sent any old units back to Apple, and they only sell the most up to date version.

    I take it home, and try connecting to both my 2009 Mini Mac AND my new 2010 i7 MacBook Pro. Same thing as everyone else. In the black parts of the screen there are white flashing lines. It looks like garbage, and I will be taking it back.

    I have a love/hate relationship with Apple! My 30 Cinema display looks great on my 2006 MacBook pro with Dual link DVI built in! Looks like garbage on all my newer macs. Thanks Apple!

    Horrible

    • Written by from San Jose

    Many issues with this adaptor. My 30 inch display works fine with my MacBook Pro and a WIndows 7 PC but with my Mac Mini (mid 2010) no go - constant flickers, blackouts and the display flashes a "video not supported" error. Lot's of turning off/on, disconnecting, etc.

    This product is junk -- is this a joke?

    • Written by from Austin

    I had to get this adapter when I went from my previous generation MacBook Pro 17" to a unibody 17" so that my Apple 30" display could display at native resolution (2560x1600).

    Sadly, whenever 1/3 or more of the display is dark to black, all kinds of horizontal interference lines randomly flash in those dark areas. If the screen is half or more black, this effect is unprofessional, highly distracting, and a constant reminder how much Apple really screwed this one up. It blows my mind how this product got out of QA and has been selling for well over a year now. Not only is this product unacceptably flawed, but so is the Apple department that oversees this product for letting it get though QA.

    I'm a hardware and software engineer (and an Apple developer to boot) so I think see what happened here. Apple built-in the display hardware (dual link DVI) in the previous MacBook Pro 17" (it did cost $3000, remember?), but they removed this support in the latest generation (likely to cut costs). The product is so flawed that I suspect there's something bigger going on behind the scenes for it to have made it past QA.

    Lines in dark areas of screen on Apple 30" Cinema!

    • Written by from Kaneohe

    I too have the adapter (V1.02) hooked between to my NEW Mac Mini and my 3 year old 30" Apple Cinema display and I am experiencing the same problems with the horizontal video static lines. Unacceptable when watching a video! I have reset everything per all the tech suggestions to no avail. I have searched for the new firmware V1.03 but have not found it anywhere on Apples site. Please post the firmware revision 1.03 Apple Tech Guys! If someone knows where to download the firmware update please post!

    Horrible, clunky LARGE piece of expensive hardware

    • Written by from Howrah

    This is perhaps the worst computer product I have ever purchased. It is extremely large, takes two USB ports to run and although it provides an additional USB port it is too underpowered to even recognize, let alone mount an external drive. I now have a situation where I have to solve the USB port deficit because of this USB hungry device.
    The performance issues cited in other reviews are true with my experience also. I am running a 20" external Samsung display and have had repeated trouble getting it to mount the display, wake from sleep, etc.
    This product is a DOG. Do yourself a favor and look for a cheaper, more elegant solution. This product is a rip-off.

    Terrible Product

    • Written by from TROY

    this adapter is plagued with problems. screen flickering, resolution issues, firmware problems, etc. i've gone through 3 of them so far. problem is that i need them for my two 30" cinema displays. i figured apple would make a better product than this, but i was wrong. all in all, you have no choice but to buy one if this is the adapter you need. when you do, you might get lucky and have minimal issues, or like me, you'll wonder why apple even sells it.

    Tried two units - still the same issues...

    • Written by from Zurich

    Just got back from an Apple store with a replaced adapter, but the issues are the same.

    3 year ago I got 30" HP LP3065 and I was using it with a 2007 15" MBP - this worked just perfect. A year ago my girlfriend bough a 13" unibody macbook and I got a couple weeks ago a new 2010 13" MBP, which raised a need for a dual dvi adapter to use the 30" screen.

    Unfortunately quality of a picture, that one is getting on a screen now is really bad - just as an example: there is a significant flickering in areas, where active window drops shadows - both on vertical and horizontal edges. On pictures, where there should be a perfectly smooth gradients there is a flickering + color noise.

    I went to Apple shop and was successful with getting this adapter replaced. Unfortunately with a new one the problems are exactly the same. I also tried attaching to other new macbooks and the problem stays.

    It is a great pity, that a pro-users have a problems with a setup, that 3 years ago (with no adapter) worked just perfect. I hope Apple will be able to solve problems with the dual dvi adapter quickly, since current issues make work on 30" screen close to impossible.

    Really disappointing...

    Complete fail

    • Written by from Oakland

    New macbook pro (core i7 2.66) + Mini Displayport to Dual Link DVI adapter, firmware v 1.02 + Apple Cinema 30" HD.

    It works intermittently, and seems to work longer when I plug in the displayport's usb directly to a iphone usb wall wart instead of the avail usb port on the macbook.

    Still, after a few hours it will turn off the cinema disp and will only come back at single link dvi resolutions. Unplugging, replugging, etc... as found in the tons of reviews on this product sometimes work, sometimes not.

    Pretty much worthless as it is more disruptive then useful.
    I am still pretty shocked that apple has not addressed this more publicly.

    worthless piece of junk

    • Written by from San Diego

    I swear this thing bugs out at least 2-3 times per week and sometimes 4-5 times per day. I have it connected to a 30" HP LP3065c monitor.

    It consistently "goes weird" and the monitor starts showing a bunch of squiggles and is completely unreadable. I have to unplug it, wait a few seconds for my laptop to adjust to having one display and then plug it in again.

    It isn't my computer - I've had three different machines and it acts the same way with all of them.

    I'm ordering another connector today to see if that makes any difference - but I doubt it will.

    Of course there isn't an alternative - very frustrating that Apple would sell junk like this.

    This is not a full DVI connector. This is a DVI-D connector.

    • Written by from luling

    I bought the other mini to dvi connector and took it back. It wasn't a full dvi connector. The apple store guy told me to try this one instead. NO Luck. This also isn't a full dvi connector. This is a DVI-D connector. Look at the area in the close up where the horizontal flat pin is. In a full DVI connector there are 4 little pins surrounding the flat blade. This connector doesn't have them. It means you can't connect to most DVI hardware. I have three very large external monitors, one is a Wacom Cintique. I can't use my new macbook pro laptop with any of my large external monitors because there is no true full dvi cable that will allow me to connect them together. I'm looking for a third party solution for an adaptor. But if you plan on buying this connector to work with your legacy monitor. Make sure you don't need those extra pin holes. If you do, this will not work for you.

    Flickering and noise with 30" Apple Cinema Display

    • Written by from Ridgecrest

    Like many other users, I too am experiencing consistent flickering and bands of video noise on any portion of the monitor that is being rendered as black when I use this cable. Now that I purchased a 2010 i7 MBP, I HAVE to use this cable and it's driving me crazy! My old 2007 MBP with a straight DVI connector worked great with this monitor. This is totally unacceptable for an apple product connecting two other apple products together!

    burned my laptop out

    • Written by from Athens

    I just got a new macbook pro 13". After plugging the monitor in, it would flicker and become grainy periodically. Eventually it became grainy to the point where it stopped fixing itself. The next day when I turned the laptop on the graphics were all sorts of messed up and I had to return the laptop.

    Figuring it was a hardware specific problem, I hooked my new one back up and it is doing similar things with less frequency. I hope it doesnt bust it AGAIN.

    Overpriced, early version extremely buggy, takes up a USB Port

    • Written by from SAN JOSE

    IMPORTANT: Adapters with 1.01 Firmware are extremely unreliable and buggy (Random static/pixel distortion until adapter is reset). Negative reviews here are from adapters with 1.01. So make sure you buy an adapter with 1.03 firmware+.

    I'm amazed Apple hasn't issued an official recall for these. If you contact support (or go to an Apple Store) and have 1.01 Firmware, they will replace your adapter...so obviously they are aware of the problem.


    Pros:
    *Use 30" monitors with dual-link dvi


    Cons:
    *$100 for an Adapter. As an Apple customer I'm used to paying a premium..but $100? For an adapter? That's just blatant price gouging.. it's disgusting.
    *Early versions with 1.01 firmware are extremely buggy, ALL are affected.
    *It needs to take up a USB Port, it has a usb port built in to make up for it but some devices need to be plugged in directly to a laptop.
    *The Adapter is kind of big


    Apple..give up on this stupid MiniDisplay port. I mean why? Replace the Firewire port and MiniDisplay port with HDMI. Enough with the proprietary stuff that requires us to buy $100 adapters.
