    Mine works great

    Purchased this after reading of all the problems. Happy to say mine is working perfectly. Running a Mac Mini and Dell UltraSharp 3008WFP.

    I have 4 gigs ram in the mini, the USB cable on the monitor adapter is plugged into a hard drive enclosure/powered USB hub, and I do NOT have the monitor connected via the passthrough USB on the adapter (its also plugged directly into my hub). I purchased a 3' dual link DVI cable from a local vendor for $20, (not the $90 ripoff from Best Buy) as the Dell monitor shipped with a SINGLE link DVI cable. No flicker, mouse issues, distortion, or any wake from sleep issues.

    I waited 5 days to post this review, to make sure no problems cropped up. Barcode label on the cable box says "january" so I would assume this particular cable was NOT recently manufactured.

    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.

    It is broken

    I have the same issue often reported here of flicker and noise coming through the adapter. For those who think it works, I suggest you test with a black background (or play a movie) as the high contrast makes the noise impossible to miss.

    It maybe, as one reviewer suggests, that people complaining merely have a defective adapter and it should be returned. Well, I did that and it still doesn't fly. Given the number of complaints here, I think it is pretty clear that the adapter is faulty. I tried two Apple Cinema displays with a new mac book pro, and I get the noise. My old macbook pro works fine. I am a huge supporter of Apple, but this product needs to be replaced.

    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.

    If it is broke, RETURN IT!

    For those with the 1 star review, did any of you brainiacs think of returning it for a replacement? I had the colored lines interference, and this may be a surprise to some, but I packed it up and went to the store to exchange it for another one. The "Genius" tested out the broken unit to verify that it was the cause, and then brought out a new one and verified that it worked properly in store. Yet another great example of good customer service from Apple.

    works for me

    I just got this adapter delivered a few hours ago and its working fine so far. I'm using it with a 30" apple cinema display and a month-old macbook.

    I was worried about whether it would work ok after the negative reviews here and elsewhere, but it seems to be just fine for me - I can not tell the difference between connecting up to my previous-model macbook pro (which has a dual DVI port built in) and my new macbook.

    Of course the price is still rather outrageous, hence no 5 stars.

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

    Great connector

    I like this so I can connect my mac book pro to the 30 in screen. It is nice because it keeps most of the cords out of the way. I recommend this to anyone who wants to hook their 30-inch to their macbook or macbook pro.

    So Far So Good

    Despite months of negative reviews I bought this yesterday for my 2.53Ghz Unibody Macbook Pro. When I first got it home I was seeing all kinds of problems running it at 2560 x 1600 on my Dell 3008wfp. The image was shifted making text blocky and unreadable. Just when I was about to go return the adapter, I tried the cable that came with my monitor. Since then I've had no issues running at full res for about 24 hours in and out of sleep both with integrated video and dedicated. I'm using a USB port on my MBP with no special configuration. If you're having issues, try swapping out your DVI cable with a high quality, short length dual-link DVI cable.

    I'm suprised and happy that it's working great, but still mad at myself for investing in a laptop that requires a $100 adapter to use with my monitor.

    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.

    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!

    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.

    So far, OK

    I got the adapter in February, but didn't receive my 17"MBP ordered at the same time until April, so didn't have a chance to try the adapter until this last weekend and week. When first connecting to my NEC 3090, the screen became fuzzy and unreadable. I unplugged the MiniDP port connector and reconnected, and it was fine. No problems since. The screen was earlier connected to my 2008 MBP with dual link DVI output.

    I'm using the MBP's USB port for power; it's clear the adapter needs it, since it gets quite warm during use. I have no downstream USB port(s) connected to the adapter. The other MBP USB ports have been connected at the same time, so the MBP seems to provide adequate power for three components. To be on the safe side, I've made sure that the adapter hangs free to maximize air flow for cooling.

    The adapter does not allow calibration software on the computer to connect to the screen; this is a known problem. To calibrate the screen, I have to use the old MBP. If I have problems later, I'll post. I've given the adapter a 3 rating because I think it's ridiculous to abandon the usual DVI connector and require customers to pay as much as Apple demands - not to mention the cost of a USB hub, where some have required it.

    flashes and ghosts

    Don't buy this. About five times a day I have to pull the cable out to get it to stop ghosting the 30" Dell and then reposition open apps back onto the 30".

    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.
