    not reliable, and bulky

    • Written by from New Ipswich

    First of all, this thing is huge for a display cable adapter, and the fact that it needs external power from the USB shows a fundamental failure in the Mini DisplayPort design. It's obviously needing to do far too much processing just to drive a display, and the $100 cost proves that.

    If the problems stopped there, it might even be acceptable, though far from ideal.
    However, this thing doesn't even keep working properly. Sometimes it goes for most of a day without flaking out, and other times it happens multiple times per hour. From time to time it flickers and threatens to stop functioning, and then when it finally happens the screen ends up all scrambled. (if you search the web you'll find pictures of this from others). When this happens, you have to unplug it and plug it back in again, or suspend and resume your machine, or do some other trick to re-initialize the display.

    I would get my original unit replaced with a newer one, except that from what I've heard even the new ones have problems, and sometimes worse than the original ones. So until I hear that the problems are fixed, I'm stuck with what I've got.

    Mostly not usable

    • Written by from Atlanta

    I've had this adapter since I bought my new MacBook in May. It was always flaky but it's getting worse. It loosing sync with the Mac and bounces back and forth between just the Mac's screen and the Cinema Display screen. And sometimes it just doesn't work at all.

    I need something that WORKS.

    Embarrassment to the company

    • Written by from Belmont

    My 30" Dell monitor worked great with my original MBP, but I've been suffering with apparently many others since upgrading to a 2009 MBP. Upgraded to SL and exchanged my adapter to v1.02 and now I have to deal with a frequent "blinking" of the screen (though now I only infrequently have the distortion issue I had with v1.01). Seems to become less frequent as the work session goes on (is it a 'warming up' issue?), and unplugging/replugging and ctrl-shft-cmd don't always do the trick like they used to.

    The worst part is the apparent lack of acknowledgement by Apple that there is any problem. I understand this may work just fine for some or even many, but it certainly seems like there are enough folks with problems to justify some response.

    New MBP and adapter, still poor quality over dark screen areas

    • Written by from Salt Lake City

    We have three older 30" Cinema Displays in our office, three new unibody MBPs (Sept 2009, latest 10.6 updates), and two new Mini DisplayPort to Dual-Link DVI adapters (firmware 1.02).

    With bright or strongly textured backgrounds, no problems at all, everything looks good, monitor stays perfectly in sync. When large black areas are on the screen and the adapters are warmed up, you start to see random red streaks appearing across the dark areas, reminiscent of the kinds of problems seen with bad analog VGA cables and older LCD displays. The easiest way to see it is to set your background to the "Lightning" image in the stock "Black & White" backgrounds. Let everything warm up for an hour or two and look closely at the dark areas at the bottom of the screen.

    With different combinations of hardware, we see the exact same problem, so it really seems to be a design issue. None of our older G4 and Intel macs with DVI ports have any problems with these monitors. Under guidance from the phone support folks, we've reset the PROM on the MBPs, cleared plist files, switched between performance and power-save graphics modes, etc, with no improvement except for brief periods between reboots when the adapters cool down.

    It gets quite annoying after a while if you are using applications with dark backgrounds. The apple staff try to be helpful, but more people need to call them and complain so that more engineering reports are filed; this is the only way to get this remedied. If you're one of the people that think that the adapters work great, please do the above background test and call in if you see noise.

    Apple has a great opportunity to show their high-end users some love here.

    Purchased a brand new macbook pro - 30" cinema display this adapter and it just plain stinks!

    I had the cinema display for the past 2 years running but using this adapter and the latest macbook pro 2.8ghz laptop I notice tons of feedback in the display.

    So bad that after 2 days I went back to my older 2.2ghz macbook pro.

    Apple please fix!

    Do Not Buy

    • Written by from Duncanville

    I own the Macbook Pro 17" unibody and a Cinema 30 display. I am running the latest firmware and Snow Leopard. I still get some distortion (e.g. sparklies) using this product. My only advice is to not buy this product. Honestly, this is the worst Apple product I have ever bought. I am happy with the rest.

    Complete garbage

    • Written by from Osgoode

    Too bad there is no option for zero stars.
    I read the reviews but this cable is the only option for large displays and the current generation of DisplayPort equipped Apple products.
    I have now tried two of these cables. One with the 1.01 firmware and with the 1.02 firmware. Both flicker, scramble the screen periodically, and cause rectangles to randomly flicker on and off (usually on the lower half of the screen). These problems exist on all the 30" displays that worked fine with my last 17" MBP, I want my built-in DualLink DVI back. Apple has made some of the finest desktop and laptop hardware I've ever used. They should be absolutely ashamed that this cable ever made it into production.

    Truly offensively bad

    • Written by from New York

    I never, ever take the time to write reviews because I just don't have the time. I'll make my very first exception in the case of this adapter for two reasons:

    1/ This is the absolute worst product I ever bought from Apple (I currently own 7 macs, no less). It DOES NOT WORK. Or it works when it feels like it and only when it feels like it.

    2/ I have to restart my MacPro at least four times a day for it to see the second screen attached to this $99 non functioning device, so now I actually have time to come here via my laptop to help prevent other people from making the same mistake I did by buying it.

    It was bad enough to be forced into buying extra hardware because Apple felt like pushing their new standard onto us (What was wrong with two DVI ports?), but at least, at the very very least, if Apple is going to pull this kinds of forced sales tactics, please try and force-sell something that works.

    Stay away.
    It will complicate your life.



    PS: for the technically orientated people:
    -the screen attached to the adapter comes up garbled and unreadable about 60% of the time at start-up, no matter what I do.
    -100% of the time garbled if the screen is turned on after the computer is started.
    -60% of the time garbled if the computer puts the screen to sleep after a long period of inaction.

    So for example, if the screen goes to sleep, I most likely have to restart the machine for it to work, but then there is a strong chance that the screen will still come up garbled anyway, unless I get lucky that the adapter sees the screen fine that time.

    $99? Really? Wow.

    confirming flicker problem

    • Written by from Nicholls

    Most people who buy this overpriced thing complain of similar problems - it flickers every now and again (completely randomly) for half a second to a second. I contacted mac support and they got me to delete two specific files (forget what they were now) but that did nothing anyway. I want to exchange it but from what I've read over the net I'm almost certain the replacement unit will ave the exact same problem! its completely ridiculous that this malfunctioning product is the only way to attach a high-res screen to the macs.

    Poor product

    • Written by from Nieder-Olm

    Screen flickers for a second every now and then, especially shortly after wakeup. What really annoyed me was that Apple support claims not to know what I was talking about. That cost me another trip to the dealer to exchange the "faulty" device, bot knowing that it's a general issue with these things. This is the worst Apple product I've owned so far!

    Failed to work on my 30' Apple Cinema Display HD

    • Written by from Cupertino

    Flickering and stripes across the screen (most visible on black) using this adaptor. The thing is this is consistent with my early 2009 Mac mini as well as my new MacBook Pro (both energy saving and power graphics) but the monitor with my old PowerMac G5 with Nvidia 7800 GT does not have this problem at all.

    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.

    Flakey Performance with MacBook Air

    • Written by from Christchurch

    Using this product with MacBook Air (Latest Model 2009) and an Apple 30' cinema display. Im experience problems with displaying images where you get bright colors on highlights and sometimes you even get colour fading from an image - noticeable if you scroll an image - ie the image starts out colour then scroll it down the 30' display it starts to go black and white.

    Not impressed - will log fault with Apple.

    fried my Dell 3008

    • Written by from Los Angeles

    My brand new Dell 3008 30inch screen started to display the reported distortion after I plugged a mouse in the monitor's USB port (first USB device I connected to the monitor). I had also just put my Macbook Pro 17"inch into clamshell mode (lid closed, working from Dell screen). Soon after the Dell monitor went from bad to worse, into the state it is now: waiting to be shipped back to Dell. It won't even display its own built-in menu any more. Something got fried in the monitor, and the coincidence would be too improbable if this wasn't related to Apple's adapter woes.

    Version 1.02 still has issues

    • Written by from PORTLAND

    I've tried the latest version (1.02) with a new model MacBook Pro and it still has issues displaying dark backgrounds with the 30" Cinema display. It appears to be the same type of artifacts that result from a too-long DVI cable, but the use of a signal booster did not solve the issue.

    It's likely that the circuitry in the adapter is not providing sufficient amplification to drive the higher-voltage DVI. Apple may need to resort to an external power supply instead of driving via USB port.

    It's very disappointing to not have a solution to this, and that Apple was not able to properly QA and ship a product that works with their own laptops and monitors.

    Firmware version update?

    • Written by from Wien

    I also have sometimes pixel noise, it can be seen best on black background and it mostly happens when the display wakes up from sleep.

    I just read the review which says that there is a new firmware version (1.02) that might fix these problems (mine has 1.01). Is there any chance to update the firmware version myself?

    It's such a shame that the 30" display is from Apple, the 15" BMP is from Apple, and the display port to dual-link DVI adapter is from apple, yet they don't seem to work at all.
