    Why Hasn't Apple Fixed This Yet?

    • Written by from Alameda

    total failure, this adapter will cut off, have to be reset hundreds of times, and cause more stress than it could ever be worth. TOTAL RIP OFF.

    Works well with high-power USB port

    • Written by from Palo Alto

    I've had this for a while and had the same trouble many people mention. It doesn't work at all without the USB connector. Moreover, it really wants a high power USB port such as found on macbooks. I think this is why so many people have varying success. If you plug it into a hub, you'll get anywhere from nothing to sparkles. The macbook USBs have higher power (as needed by iOS devices). If you use the AC USB adapter that comes with an iOS device, I think you'll have far better results.

    I'm on my second one and it has the exact same problem as the first...horrible video-noise/bands visible on any area that is black on my 30" Cinema Display. I'm a huge Apple fan, but this thing is just bad.

    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!

    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.

    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.

    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!

    Apple has upgraded the firmware and improved the adapter.

    • Written by from Clinton

    I purchased one of these adapters a few months ago and had nothing but problems with it. Recent reviews on this forum had improved, so I called Apple and asked it the adapter had been upgraded. After some discussion it became clear that the firmware had, in fact, been upgraded. The current version of the firmware is 1.02 and it works great!

    Since the firmware couldn't be upgraded electronically by e-mail, Apple replaced my adapter at no cost. The new adapter has solved all of the previous problems.

    I am seeing the same problems as everyone else. It drives my Samsung 305T plus for a while, but then it flickers and vertical stripes appear, requiring a reset.

    Waiting for a fix, firmware or otherwise.

    It simply does not work

    • Written by from Wien

    Connected the adapter to my 30 '' cinema display - every few minutes flickering, sometimes the whole screen goes snowy and distorted and I have to reconnect.

    Thanks Apple for making such a great Pro-product!!

    Colored streaks over dark areas with 30" cinema display

    • Written by from Los Angeles

    I have two problems with my Macbook Pro, this adapter, and a 30-inch Cinema Display:

    1. Very visible colored streaks over dark areas of the screen, especially black areas. This problems varies in intensity, but it's always present. I connected a coworker's MBP to my display and saw exactly the same symptoms.

    2. Jumpy mouse cursor, at others have reported.

    I suspect both problems are MBP issues rather than a problem with the adapter, but in any case, as this adapter is the only way to hook a late-2008 MBP to a 30" ACD, buyers beware. I am using this system for technical work, so for me it's a merely big annoyance, but if I were doing creative work, it would be totally unacceptable.

    Apple needs to acknowledge the problem!

    • Written by from Birmingham

    Cmon Apple...you have got to provide support for 3rd party 30" displays, not just your own. Product is great idea if it worked. No success with my Gateway XHD3000 and MBP(2.8ghz)

    Fuzz at sporadic times

    • Written by from San Rafael

    I read the complaints in the other posts, and hoped that it wouldn't happen to me. I finally received my adapter today, and was glad to be able to hook up my 30" Cinema display to my MacBook Pro. Worked great for a few hours, then the entire screen turned to snowy fuzz. Then flickered back to normal... good for a few, then back to snowy fuzz.

    Now I'm just waiting to see if this is a long-term issue.

    Fuzz of Death and flickering

    • Written by from Eagan

    As is this product is broken. For me when used with a Dell 30 I get random flickering from time to time and at least once a day the famous "Fuzz of Death". The only solution at that point is to disconnect the mini-dvi and reconnect. I was not happy to wait 2 months for this box, and I am not happy that it does not work. Stay away until Apple fixes it.

    Flickers and shuts off

    • Written by from Anchorage

    I've got one of the brand new unibody MacBook Pros and also just purchased a 30" Cinema display, seemed like a great idea to me. Then I realized that I needed the $99 adapter, ok, well drat, whatever as long as it works. Got my adapter in the mail two days ago. So far I don't have all the artifacts that people are talking about, but if I shut the lid on my MBP I can't get it to wake up for more than about 3 sec at a time then it flickers and goes back into sleep mode. The only way so far I've found is to restart my machine (in those 3 sec its awake, gotta be fast) then it'll work ok for a while. I haven't used it long enough to see the artifacts or lines yet.

    I am very disappointed. $99 and two months of waiting later, I got a product that doesn't work to spec. My Samsung 30" display (which conforms to ALL the specifications Apple laid out on its product literature for the MacBook) goes out of sync every few minutes. Unplugging it and plugging it back in gives me a few more minutes. This is not a useful product for me. Considering that I purchased the MacBook for the sole reason that it featured Dual Link DVI output, I am feeling swindled.

    Poor performance

    • Written by from Ferndale

    The adapter works, but not anywhere near satisfactorily. "glitches" in the display are seen all the time, especially in black patches of the screen.

    Sometimes after going to sleep, the monitor will ghost the display three different times.

    You have to unplug and plug the monitor back in several times a day.

    My 30" cinema display is sad and my workflow is interrupted constantly.

    Shame on you Apple. Do you care about us? Or just those people buying your new LED displays?
