    It works - for those who can't get it to work read below

    I read all the negative reviews on here before buying and still made the purchase anyway to try it for myself. Don't forget everyone - most people who write reviews on the Internet are complaining about something. The majority of purchases that work never get written about because it is as expected. So always take "reviews" with a grain of salt.

    So anyway, I hooked this "Mini DisplayPort to Dual-Link DVI Adapter" up to my MacBook Pro (2.53GHz model) and to my 30" Apple screen. YOU HAVE TO MAKE SURE YOU ARE RUNNING YOUR GRAPHICS IN PERFORMANCE MODE to not get any color or tearing issues. You might also need a fresh reboot to make it reset as well.

    1) Click on your battery or charging icon in the upper right hand part of your screen
    2) Click on "Energy Saver Preferences"
    3) Ensure that the "Higher performance" button is selected when connected to the adapter (you can switch it back when portability is needed)
    4) Then exit


    1) Go Apple>System Preferences> and click on "Displays" in the Hardware section
    2) You can play around with the settings in here to get the resolutions, colors and displays set-ups however you want.

    **Important note - make sure your laptop is using the battery charger when connected to the adapter for all of the above to work consistently.

    Hope this helps - worked for me.

    DisplayPort Adapter (or Nvidia driver) Freezes/hangs macbook or causes snow

    I, like many here, am having problems where one of these behaviors occur when I connect the DisplayPort adapter:
    - There's snow on my external display (Samsung SyncMaster242MP)
    - The external display blinks on then off.
    - After returning from display sleep, the monitor continues to display nothing (black).
    - The MacBook hangs when removing the adapter and then plugging it back in. But not every time I do this. And I'm usually doing this to get the MacBook to re-detect the display due to one of the aforementioned issues.

    There was mention of an Apple update to the MacBook Pro Nvidia drivers that occurred in late January. That update has since been removed by Apple from their support site.

    I'm giving the adapter a two star rating because it does work, for as long as I keep the MBP from not sleeping the display, once I convince the MBP that there is a display attached and it syncs up without snow.

    Soooo...I'm anxiously awaiting news from Apple in some form (support KB, new driver, new adapter, anything!).

    Awesome =] works GREAT!

    I got this for my 42 in PHILIPS LCD 1080p. I was very disappointed at first as it did not work, but after reading some of the reviews on here I realized I had to plug in in the USB to supply power to the dual-link (I know Duh!). Now, it not only works but the picture is crystal clear!

    hence my review title, Awesome =]

    Apple changes product description

    This product description use to state this adapter would work for any monitor that required a dual-link dvi connection.

    After receiving multiple complaints, Apple has changed the description to include only their 30" cinema display instead of fixing the real issue.

    The adapter WILL work with my 30" Dell display, but I occasionally will experience issues (static, snow, etc) - only a reset (computer, display, settings, sleep) will bring it back. A serious nuisance.

    Works great with MacBook Air

    The adapter works great with MacBook Air (late 2008 of course). Is seems that the USB plug is just to provide power to the big adapter, without connecting the USB cable it does not work.
    It works perfect connected to Logitech 4-ports USB hub (the hub is powered). The screen is 30-inch Apple display. Image is perfect. The only problem is that keyboard and mouse works better connected to the hub not the monitor - the movement of the mouse is smooth. Expensive but definitelly works.

    I thought I would be one of the lucky ones after waiting 3 months for my adapter.... I guess not. I have slight flickering and my wired mouse tends to be very jumpy. Honestly, if I would have known this beforehand, I would not have bought the new MBP.

    Slow MacBook Pro

    After paying $99 plus tax, I thought I will be very happy driving 30 inch Apple Cinema Display from my new MacBookPro. Wrong! It is SLOW !!! Especially when I run VMWare Fusion full screen mode, my Mac runs so slowly that I fall asleep. I am not sure why they made MDP to run only half the capacity. Apple must have known this, so then they should have left dual DVI or provided a different solution.

    Problem's with 30" Display

    As others have stated there are many problems with this adapter and using it with a 30" display. I never had a single problem with my two prior 15" MacBook Pro's and my Dell 30" display. With this adapter I experience flicker every 10-15 minutes and have seen it drop one link of the dual-link connection as well. I would avoid this adapter and had I known this would not have purchased a new 15" MacBook Pro.

    Apple 30 inch Cinema Display Flickers

    I did not need this adapter with my late 2007 Model MBP using the internal DVI connection. However, living on the bleeding edge, I had to get the new MBP back on Dec 31, 2008. I since learned the hard way that I needed this new Mini-Port to Dual-Link DVI Adapter to match the resolution of my previous MBP. Then I got an unexpected


    This thing flickers under all circumstances. It doesn't matter if I just turned the MBP on, or after hours of use. I have been trying workarounds that others have tried and have been sifting through rumors of hardware issues, software issues, or environmental causes to the problem.

    I am not one the usually writes reviews on products, but I simply could not let this one slide. I too read the reviews prior to purchasing this product, and I did not see one mention at the time to this particular issue at the time. Now I see that others are experiencing the same problem. I encourage everyone that has purchased this product, and experiencing these issues to voice there feedback. I would tell others to hold off on purchasing this product.

    More importantly if you use an external display and are considering a new MBP I would hold off until there is official word from Apple that the issues have been identified and resolved with either this product or more seriously a new generation of MBP.

    Does not work with 30" Dell and MBP

    We use 30" Dells and Macbook Pros at work, and between two machines and monitors, we're determined this product is terrible. I've tried working with the lid closed, re-plugging from the monitor end, the laptop end, tried the "official fix" from Apple including deleting plist files and resetting PRAM, and still see the sudden loss of clarity/fuzziness/noise issues I've seen that other have photographed. My hope is that Apple will replace this cable with one that works, my fear is that no cable will work and no 3rd party cables will be available.

    doesn't work properly with Macbook Pro (late 2008) and Dell 30" monitors

    beware, doesn't work with a Macbook Pro (late 2008) and any Dell 30" (3007wfp /3007wfp-hc), every so often the infamous 'fuzz of death' appears and your screen will be unreadable, leaving only a re-boot or unpluging/repluging the adpater to bring the screen back, but only for awhile.

    check out the forums for details, especially the thread intitled - 'periodic Dual-link display problem with new adapter'.

    very poor show from Apple to release a faulty product.

    Disappointed by this poor product

    As everyone else has mentioned, this product (as currently integrated with OS X) is defective.

    Apple delayed the release of this product, charged an outrageous price, and then did not provide the necessary software updates to make the product work.

    I have new MacBook Pro 2.53 with a 30 inch Apple Cinema Display.

    My mouse jumps several inches sporadically. I've seen in forums online that there is an easy way to replicate this problem. Drag the mouse in a circle over and over. Every few times, the mouse will jump several inches.

    In addition, the screen flickers, changes colors, etc.

    I'm confident that this is just a software problem. (I hope so). Apple MUST update this product, software, or refund the customers. At the moment, we bought a dud.

    Design Engineering Staff Shouid be Publicaly FLOGGED!!

    Please forgive my possibly ignorant rant knowing I am open to any schooling from an informed source, unless otherwise corrected I believe the Design Engineering Staff at Apple should be publicly Flogged or at the very least be made to give up a portion of their paychecks to accommodate the prolific permutations of video connectors Apple has SPAWNED! Really now, Intel / PC based computers, that offer equivalent graphic performance have managed to utilize the same 15 Pin cable for 20 years!!! Could someone please tell me WHY APPLES FEELS IT IS COMPULSORY EVERY TIME A MODEL OR MID MODEL CHANGE HAPPENS THEY MUST INVENT ANOTHER *&!@#!# VIDEO CONNECTOR?!!!! One must carry a printed product compatibility map the size of a bed sheet to PURCHASE the correct $30 to $125 adapter so that one can connect AN APPLE MONITOR TO AN APPLE COMPUTER!!! Shame on Apple once again for showing absolutely NO ALLEGIANCE to Long Standing Consumers! I had hoped Intel would have put a stop to the 8Pin, D-Sub, BNC, 15 Pin, Powerbook 100 Series adapter, Powerbook Duo Adapter, DVI, VGA, Mini DisplayPort to VGA, Mini DVI to VGA, Mini DisplayPort to DVI, Mini DVI to DVI, Mini DVI to Video, Mini DisplayPort to VGA, Micro DVi to Video, MADNESS!!! Just to name a few.....

    Monitor flickers every 20-40 minutes.

    Our office has 9 of the new MBP laptops that require these adapters to drive our 30" monitors. I personally have a 30" apple display, all others are 30" Samsungs. Every monitor regardless of brand or age flickers (blanks out and then comes back on) every 20-40 minutes. None of the monitors exhibit this behavior when using a direct DVI connection to an older MBP. Problem is either this adapter or the graphics chips in the new MBP's.

    Working fine after 3 days...

    I have no doubt there are significant issues with some or most of these adapters, but unfortunately it is the only way to hook a new MacBook / MacBook Pro up to a 30" monitor; anyone who has such a display is unlikely to give it up.

    I bought one of these from the local Apple store, and tested it in the store with a Macbook Air + a 30" cinema display they had there - worked fine. After 3 days of 8+ hr/day use with a MacBookPro purchased in Early Jan connected to a Dell 3008WFP it is just fine - display rock steady, no issues whatsoever. The MacBook is plugged in (powered), one of the MacBook's 2 USB ports powers the adapter, the other goes to the USB hub located in the monitor. Energy saver is set to "better battery life" (ie 9400M); haven't bothered to enable the 9600.

    Yes, this is far too expensive, large, and generally a ridiculous solution - particularly compared with the direct-connect dual-link DVI on the previous generation. And yes, why is there not a mini-DisplayPort to DisplayPort cable available, 4+ months after the product introduction? However, the particular unit I appear to have works just fine. If you really need one of these things, perhaps you can get lucky and wind up with an operational unit as well.

    Otherwise, sticking with a previous-generation MacBook with a more immediately useful display connector, or perhaps a different brand of laptop all together would serve as a better solution.

    Joining the crew on the ship of fools

    Nothing extraordinary to report. I'm making a mark in the vain hope that the sheer number of lemmings that are taking one for the Apple Team will somehow see redemption with Apple coming clean on this, and resolving the Mini DisplayPort issues. I hope it's the adapter, and not the Laptop hardware. I've got a 15" Unibody, full CPU & RAM, and a TripleHead2Go setup. It runs absolutely fine off my older MBP, and can't wake from sleep on the new one without serious scanlines, artifacting, and confusion. I've wasted 8 hours jacking around with this - who can I bill for that?

    Poor performance

    After waiting 2+ months for this product to come out, then paying the $99 for what amounts to a cable adapter, I find the performance to be poor. At "millions" of colors (set in Apple Display Prefs), I get a constant flicker. At "thounsands" the flicker is manageable at 1/hour or so.

    Apple SHOULD do something to recall/fix this adapter.

    Buy this adapter or they'll kill your dog

    I initially purchased the single channel adapter not being aware of the 1280x800 signal limitation. I returned to the store (without packaging, but with receipt) and explained that it was unlikely anyone on the planet would benefit from the single channel adapter, and the staff agreed. I was given full credit for the single channel and purchased the dual.

    It worked as expected, and I am running 2560x1600 w/millions of colours. No flicker, no warbles. Samsung 30 inch SyncMaster 305T.

    So why a 3 star rating? Because it is a solution after the fact. My old MBP had a DVI port on the side and ran this monitor just fine. Exactly how is this Mini DisplayPort suppose to benefit me? There is a high PIA factor plugging two cables where prior I had one and now I have 3 feet of cable and a box the size of a deck of cards on my desk.

    So in summary.. If you are reading this, chances are that you already purchased a new laptop and are trying to solve your display problems. Go ahead and buy it.

    Wait for them to fix the bugs before buying

    If you want to use a new MBP with a 30 inch cinema display, you have to buy one of these. But there are a lot of bugs still to be fixed, such as:

    - scrambled video after wake from sleep
    - stuttering playback in Front Row
    - jumpy cursor movement
    - momentary video blackouts

    My advice: don't but this (or a new MBP) until the problems are fixed. Check the forums for the latest reports...

    The device is also cumbersome and ugly, doesn't have a firewire-thru port and is rather expensive. That might be OK .... if it worked properly.

    It's not the $100 adapter, it's your $2700 computer

    I have both a MacBook Pro and a MacBook. The adapter works great on the MacBook and lousy on the MacBook Pro.
    On the MBP it flickers and loses sync on a regular basis.

    Also consider that it uses a USB port for power. Granted, there is a pass through port on it, but that can't even run a keyboard/mouse.

    I don't know what Apple's said (can't find anything), but I've read that the problem could be the USB power regulation. Meaning mainboard. Meaning good luck getting that fixed.

    Still, it's better than a PC any day!
