    alas, this mac hardware does not work well

    it's the only way for me to attach my macair to 30inch LCD monitor (Samsung 305T), but it does not work solid at all. Every couple of hours or so image gets bad and I have take it out and plug it in again. Hopefully it will be fixed or 3 part cable will become available on the market.

    Unfortunately I have to chime in and complain.

    I'm using this with a Samsung SyncMaster 305T. Some days I have to unplug and plugin this adapter to reset things once or twice a day. Other days though it's Every 10 minutes to the point I'm about to throw it in the garbage. The screen goes "blurry"... it's kind of hard to explain how it looks, but it's definitely unusable in that state.

    I'm hanging on till the day that Apple may be able to solve this issue with a software and/or firmware upgrade. PLEASE!!!

    Don't buy this counting on reliability.

    Flicker

    New 17" Macbook Pro and 4 year old 30" Cinema Display. I have my display set to "Higher performance" in the Energy Saver preference pane.

    When displaying large areas of black on the Cinema Display there is clearly flickering horizontal lines. I once tried unplugging and replugging in the connector and the flickering was a bit less. But I do plug the adapter in virtually every day since I commute with the laptop. Generally speaking it will flicker when displaying black areas.

    I will probably try to return it for another one to see if it varies.

    I can live with it if there is no fix as the flicker is only there in black areas.

    Does not work. Please fix it, Apple.

    Tried this with a Dell 3007 monitor. No luck. It worked for 4 hours, then the picture changed to look like an old TV - lots of snow. Waiting for Apple to get this product working correctly. Hope it is soon!

    Doesn't work as it should

    Connected to a Dell 30" screen ; the picture goes fuzzy every few minutes. You must unplug/replug the mini-DP adapter to fix the problem.

    A real pain... And no update from Apple after month of having this issue. And I'm not alone.. Hundreds of similar post with the problem

    Fragile and unreliable

    The Mini DisplayPort IMHO is a disaster!
    Received two new MacBook Pro's a couple of weeks ago. First time one was used we had problems with Dual-link DVI display
    Second unit developed a fault with its Mini DisplayPort to VGA connector (no blue displayed - very embarrassing during a client presentation!)
    Apple need to deal with this

    Worst Apple Product Ever

    I've had two of these so far...I tried them both with a 30" Apple display and a 30" Dell display driven from three different computers - a 24" iMac, a 13" Unibody MacBook, and a 15" Unibody MacBook. In every case the end result produced either a flickering display or a display image that had no depth (i.e. it looked shallow and out of phase).

    To begin with, it's disappointing that Apple forces you to buy this for their new line of MacBooks and iMacs. But to produce a product this lacking in quality, it's ridiculous.

    I'm so disappointed with this product, that I've just downgraded to a 2.5 GHz MacBook Pro so that I can run my 30" display without problems.

    Apple needs to fix this or design a new product! I'm not buying a Unibody MacBook Pro again until you do.

    Works beautifly with Dell 3007WFP-HC

    Hooked up new 30 inch dell monitor to new imac - no problems - recovers from sleep perfectly.

    Terrible - defective junk

    Bought it for my uMB, tested it and it left all sort of distortion lines everywhere. Slightly better if you plug the USB into an external USB power adapter but that lasts 10 mins. There needs to be a recall on this. I returned it the same day.

    Awful product

    Have this connected to a mini and my Dell 30" ... after wake from sleep, the screen will invariably muck up (as described in other posts) requiring me to reconnect the adapter.

    I expected better Apple. I expected it to work.

    Perfect

    Works exactly as described... no issue here! Remember, most people satisfied with this adapter WILL NOT post a positive review!

    fail, bigtime

    When the computer wakes the monitor up out of sleep, it has about a 1 in 4 chance of having lost sync with the monitor. So I get two images superimposed, about an inch or two apart; impossible to use. This same monitor has worked flawlessly with my previous-generation MBP (which had direct DVI out) for almost two years, so it is either the new MBP or the adapter. I suspect the latter; I tried a lower-resolution "normal" mini displayPort to DVI adapter and had no problems at all ... other than the lack of resolution. Apple support seems surprised at the problem; odd, given the feedback on this page. I think I'm going to return the MBP and go back to the old one. Sigh.

    Minor problem: occasional flicker, but limited mostly to waking up.

    Don't buy it until fixed

    I just bought the adapter at the Apple store today. I though they possibly could have fixed the flicker and distortion problems seen by other users.

    Hooked it up to my Dell 3007 only to discover both the flicker and distortion are present intermittently. Approximately two times an hour. Forcing me to put the display to sleep and wake it up to resolve the problem

    I would stay clear of this until a working fix is released.

    Serious noise / interference problems - as widely reported

    I purchased one of these (expensive) adaptors for use with a new MacBook. Unfortunately there is serious interference on black parts of the screen. Many other users have encountered this, so I don't believe my experience is uncommon.

    Works fine for me.

    Not sure if they revised the product or what; but I'm finding this product is working extremely well hooked up to a Samsung 305T. I used to have the straight DVI dongle hooked up to an HP 24" LCD panel, and frequently had trouble with the video output occasionally being unsuitable for the panel and requiring a display sleep and then rewake to rectify. I haven't had to do that since switching to the 30; and the display is gorgeous.

    FAIL

    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.

    Terrible Product

    We bought 6 of these for work to connect the new Mac Minis with our 30" Samsung displays. Many of them have problems, and need to be disconnected and reconnected several times an our. Apple should be ashamed to have it's name on this product. It is garbage!

    Terrible

    Received with new Nehalem Mac Pro... fuzzes out about every 30 minutes when connected to Dell 30" monitor. Have to disconnect and reconnect the monitor to get it to come back.

    Apple: This MUST get fixed.

    Fundamentally Flawed Product

    I'd actually give it zero stars since the product fails at the one thing it's supposed to do -- the short is that all current macs, except for the mac pro, do not really support DVI based 30" displays, and the mac pro only supports one, contrary to product documentation. As Apple has yet to update their 30" display to native display port, this does include their 30" cinema display as of this writing.

    The long of it is that it appears that adapter is intolerant of its power source. The above makes the decision to use USB power instead of having a proper adapter a very BAD decision (not sure why they didn't just make a power adapter -- it's not like you are going to tote a 30" display around like a laptop). The result is that you get snow artifacts on the screen, which range from annoying, to distracting, and into the downright not usable range depending on how good or bad your power source is. Either the team who QA'd this product, or the pointy haired dude who ignored them and let it out the door should be fired. Apple needs to recall these and replace them with, I don't know, maybe functioning adapters? A tip -- a real DC power source that provides the consistant power needed by the adapter instead of reliance on an USB bus would work better.

    PS: That said the best power source I've found thus far is an Apple iPhone charger -- I happened to have an extra and tried it as well as a few other USB powered devices. So far it's the most usable of the lot, tho I still get significant snow and flicker even with it.

    Bought 4/6/09 fails exactly as described by others.

    Bought new Mac Mini, + dual-link DVI adapter together. Its driving a 30" Samsung 305T at 2560x1600.

    Video looks perfect for about 3-10 minutes then becomes scrambled with an interlacing artifact. Unplug/replug the DVI cable fixes the issue momentarily. Video flashes on/off at random every few minutes.

    There is nothing wrong with the monitor, I've been driving it at 2560x1600 from my previous generation 17" Macbook pro with 0 problems.
