    You cannot run dual monitors with this product or the Mini DisplayPort to Dual-Link DVI Adapter.

    The Mini DisplayPort to DVI Adapter is meant for 1 external display up to 1920 x 1080.

    The Mini DisplayPort to Dual-Link DVI Adapter is meant for running 1 external display up to and beyond 1920 x 1080 resolution, such as the Apple 30" monitor which runs at 2560 by 1600 pixels.

    Please do your research before recommending a product. Dual-link does not mean Dual monitors. The Digital formats are available in DVI-D Single-Link and Dual-Link as well as DVI-I Single-Link and Dual-Link format connectors. These DVI cables send information using a digital information format called TMDS (transition minimized differential signaling). Single link cables use one TMDS 165Mhz transmitter, while dual links use two. The dual link DVI pins effectively double the power of transmission and provide an increase of speed and signal quality; i.e. a DVI single link 60-Hz LCD can display a resolution of 1920 x 1200, while a DVI dual link can display a resolution of 2560 x 1600.

    Please purchase the correct adapter for your application.

    Confucius says: Researching a product BEFORE buying leads to satisfaction!

    • Written by from Fairport

    This is an excellent product that performs quite well if you understand its intended purpose. I use it in conjunction with a 22" HP w2207h LCD monitor via DVI to HDMI cable. I have no complaints. Any limitations are a result of the way Mini DisplayPort has to "emulate" a legacy DVI signal or the monitor itself, not the actual adapter.

    It appears that some people are being mislead into leaving bad reviews, but in the end, User Error is to blame. To clarify, this is a SINGLE Link DVI adapter, intended to be used in conjunction with a SINGLE external monitor. Apple also sells a "Mini DisplayPort to DUAL-LINK DVI" adapter if you need to run, you guessed it, dual monitors!

    That said, if you purchase a SINGLE-link adapter intending to run DUAL monitors, you'll be disappointment and logically assume it's because your MacBook Pro is vastly inferior to your neighbor's Vista laptop, not because you purchased the wrong item!

    HDMI source limited to 1 monitor???

    • Written by from Lansdale

    Ok, using a new MB with a Mini DisplayPort to DVI, then converting it to HDMI, I am unable to hook up 2 32" LCD monitors. Only 1 external monitor can be used. I am told by Apple support that the MB isn't "powerful enough" to send a signal to 2 external monitors. Funny, I can do just this with a Vista PC Laptop with NO PROBLEM.

    Samsung Syncmaster 23 inch - WILL NOT WORK WITH THIS!

    • Written by from Atlanta

    I just spent 30+ minutes on the phone w/ tech support to find out the my brand new macbook pro (with mini display port) will not work with my 23 inch Samsung Syncmaster. PERIOD. It doesn't work. Its fuzzy -- no matter what resolution you put it on. My option : spend 3x what I spent on this monitor to buy one that definitely works. Great Apple -- people already are Apple fans without being forced into buying your other products. This actually does the reverse -- makes me wish I'd never bought a macbook. At least with a Dell I know I use pretty much what I can find.

    Slow Response Time

    • Written by from Singapore

    I connect my MacBook with my Samsung 931c with his cable. I found that there is a delay in the display output, anyone is seeing the same problem. You can observe that the display is not as smooth as the display on the notebook itself. I wonder it's due to the signal conversion.

    FYI, no 1920x1200

    • Written by from SOUTH SAINT PAUL

    It was my understanding of the single-link DVI spec that it could handle the 1920x1200 resolution of my 26" monitor. Seems like 1920x1080 is the max, so I just wasted $30. Whoops.

    Mixed feelings

    • Written by from Portland

    The adapter is DVI-D, meaning it has a digital only signal. It connects well to my Toshiba HD-TV using this adapter and a DVI-D to HDMI converter cable. Resolution is excellent, recognition of the second display is easy.
    However, many projectors and adapters (not necessarily very old, and certainly widespread in use) support only VGA or connections for DVI-I (digital + analog).
    This adapter is often incompatible, and I've been forced to buy the extra $29 VGA adapter to use my MacBook Pro for presentations.
    For this reason, a mediocre review.

    Overall great product if you know the shortcomings

    • Written by from BIRMINGHAM

    I am using it with a Samsung 245BW 24" LCD bought from Costco. It works perfectly until the computer dims the screen. Once the Macbook dims the screen the Samsung will start to flicker, jump around and never be stable. Restarting corrects it.

    If I never let the monitor dim or go to sleep it works flawlessly. Just be aware that if you are having flicker issues it is probably because your computer went to partial sleep.

    Audio interference

    • Written by from Glasgow

    MacBook Air. Cable is fine for picture only (connecting to a retail Sony LCD 42").

    However, a high pitched noise is noticeable from the speakers when the audio out is used to link to external speakers on the monitor / TV or headphones. When DVI cable is removed, sound interference disappears. Suspect that internal cables are not shielded?

    Pathetic. The noise is so severe that is impossible to watch TV programmes on the larger screen, which was why we bought the cable in the first place.

    Apple dropped the bomb really badly on this one.

    • Written by from Houma

    The new Apple Macbook pro does not have a way of connecting with a third party monitor unless you purchase this connection. For a $2000 dollar machine, they should add this. I'm really tempted to return this one, and go ahead with using the old one just because of that.

    I ordered this connector online, but I failed to realize that the mini-Dvi to DVI connector isn't the same. That is my fault. I'll order it again. Now I have to wait another week for this connector to arrive. This is just one huge headache.

    I'm very frustrated and disappointed. :(

    • Written by from Novosibirsk

    Has grave issues with my external HP LP2475w monitor - screen flickers every several seconds and makes any work or entertainment impossible. Also when the computer wakes up, for 2 or 3 seconds the screen is covered with "noise" pattern. I have tested 2 adapters with 2 identical HP monitors (and with monitors from Acer and Samsung) - no luck, one flickers more, the other less, the problem is clearly not on the side of monitors (they work flawlessly with ANY other signal source).

    I'm very disappointed with Apple regarding this new Mini DisplayPort mess. At least you could sell MiniDisplay Port to DisplayPort adapter so I can connect my monitor with it (Monitor has DisplayPort socket on it).

    Works just like it should

    • Written by from Wichita Falls

    I have this hooked up to my new macbook and a Samsung T240HD - works great!! I was utterly confused about this product looking at it and my DVI cord. This adapter shows a slash and then 24 squares with no gap inbetween. IT WILL WORK IF THERE IS A GAP on your cable. And if you don't know the difference between DVI cables - look it up, it's not hard. If you have one slash on your port it will work, if you have two it will not work.

    Not compatible with Apple DVI-VGA adapter.

    • Written by from Vancouver

    I was happy to see the results when I hooked up my MacBook to my TV, but then when I tried to use this adapter with an older Apple DVI-VGA adapter cable, no go. I needed to connect the two in order to use a data projector with only VGA inputs. Now I have to scramble to find another way to use the projector.
    Apple Store employees should tell you up front that this adapter isn't compatible with older (analog) cables, but they don't. That's why there are MANY people with experiences like mine.

    Bad product listing

    • Written by from Inyokern

    I am so disappointed. All I want to do is hookup my Macbook Pro to my TV so that I can play home movies, etc., which were edited and compressed on my computer. However, the listing of this Mini DisplayPort to DVI did not make clear that the cable was DVI-D rather than DVI-I. I'm not a pro at these things, but I'm not dumb. If a listing says "DVI-I" and one says "DVI-D", I can figure out that they are different and order the right ones. Thumbs down apple.com. >:(

    Works as expected IF you know your "Late 2008 MacBook Pro" settings

    • Written by from Portland

    I had just got a new "Late 2008" MacBook Pro 15", and I was frustrated with getting 1920x1200 resolution to work with this adapter and any non-Apple LCD monitor. The display would switch to 1920x1200, but the image suffered intermittent video noise (e.g. red lines streaking across the screen, jumpy video, etc). I thought something was wrong with the video card or the adapter. Long story shorter, it turns out this model of MBP has two NVidia chipsets (I knew that, but didn't know how to switch them or which was dedicated to which port, etc), and that you can force the "better" chipset to be used by going to the Energy Saver pane in the System Preferences and choosing "Higher Performance". That fixed my problem instantly.

    Not your usual DVI

    • Written by from College Place

    Works great for digital only DVI. Will not work with a DVI to VGA adapter or some DVI cables.

    I bought this expecting it to work just like the DVI port on my old MacBook Pro, found out it didn't when I was trying to hook a projector up for a colloquium presentation I was doing.

    Don't forget to buy the VGA adapter as well if you are ever going to need to use VGA.

    Works, but bad design

    • Written by

    It does what it's supposed to, but I can't stand the design. My beautiful new macbook sits on my desk, and I'd like the 4 cords connected to it to drop down inconspicuously through a cable grommet -- but they can't because of the big blocky connector which sits only a few inches from the computer. Why couldn't Apple either make the cord longer, or better yet, just offer a 4' cord with mini-displayport on one end and DVI on the other??
