    Not Compatible With Many Displays

    I'm not sure if the signal from this doesn't meet DVI spec or what but if I try to run above 24 Hertz on my projector (which I use with other computers at 60 Hz, progressive in both cases) I get intermittent static and blinking. I have a similar problem with a Dell LCD when I try to run it through an ioGear KVM. PCs going through the same KVM drive the monitor at the same resolution and frequency with no problem (even if I swap ports on the KVM to make sure it's not a bad port). I figured the Apple brand adapter would be the gold standard, especially based on price, but I'll have to try another brand of adapter now. Weak.

    Great for dual-screen setups.

    I use this to dual-screen with my 15 inch MacBook Pro (mid 2010), on a monitor I share with my Mac Pro (2006). It works perfectly. Setup couldn't be easier, just plug it in and you're ready to go. Image is perfectly fine (screensaver looks amazing on two screens, as does my desktop slideshow). No issues or complaints to report after using it for three months.

    Figured it out

    wondering why your displayport isn't working right? think its broken?
    external screen is not recognizing your video signal? try restarting! i finally figured it out. I have a macbook pro unibody 15". displayport to dvi-d cord to hdmi. I returned my first display port because i thought it was broken.guess not, i have to freaking restart every time for the displayport to be recognized!

    Not all interfaces created equally

    Just a warning:

    I purchased this to use with a Dynex DVI to VGA adapter. I could not use it. Dynex has extra pins around the wider and flat "pin"on its DVI interface that the Mac DVI interface does not support.

    Connection is not solid; picture snows or blacks out.

    I am using this with a late 2008 MacBook (aluminum).

    Bought two adapters. First one was awful. I connected the cord to the adapter with varying degrees of snugness. No matter what I tried, it would not maintain a connection. The screen (Samsung SyncMaster) was either black, snow, or worse and equally often, it would would just constantly flicker/sorta oscillate between my desktop and snow (many times per second). There was no consistent pattern to get it to maintain a picture (I mean, I tried to wiggle the adapter), which meant that it wasn't the actual mini-display port for which I was having the problem, and that it was the DVI side of the dongle that was having issues. Sometimes I would get lucky, and it would hold a picture for 10 minutes (this happened twice). I wasted four hours on this defective product. I tried switching the DVI monitor cables, but the situation was consistent (and for the past year, the cables have worked and are working just just fine connecting the monitors to the desktop PCs).

    Next, I bought another adapter. This worked much better for the most, but it is still not perfect. I've only used the new one for a day, but I am very concerned that it will last, and that it will soon regress to the defective performance of the first adapter that I bought. Once during the day when the new adapter shifted, I did lose the picture on my monitor. That's how I know things are not perfect.

    Might try buying a third adapter.

    Be sure your battery charger is attached to use this adaptor

    At first I thought this cable didn't work. Well... unless your macbook pro is attached to its charger - it won't work. It will work for a few seconds - then lose the external monitor signals.

    Once I hook it up to the charger - it works fine.

    DVI-D ONLY

    Very important to make sure you have a dvi-d cord not dvi-i. The main difference is that dvi-i has 4 additional prongs (2 above and below) the horizontal prong. I even tried to use my old macbook dvi to vga adapter and it would not fit as even the old mac adapter is dvi-i. Who knows why they changed.. Pretty disappointed as this was not mentioned on the sales page. Gave an extra star due to the quality of apple products being top notch. Also disappointed that apple does not carry mini-dp to HDMI, which is the only digital format my tv supports.

    Mini Displayport to DVI Adapter

    The Female DVI-D Adapter end has limited compatibility with many other Male DVI components. ie. The apple DVI adapter end does not have the necessary holes for the additional 4 pins found in many Male DVI adapter ends. (I learned the hard way). *FYI: You may save yourself time, money, & hassle if you buy a more compatible 3rd party adapter w/ the 4 holes in the beginning.

    FYI, no 1920x1200

    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.

    Works fine, but where's the RCA/S-Video out adapter?

    This cord works well on my TV, but I used my previous Macbook constantly to show friends and family pictures on their TVs via S-Video and RCA analog video. Now my new Macbook can't be connected to most older TVs that only have an RCA video plug or S-Video. Bad enough to upgrade my Macbook and have to buy new expensive adapter cords, now they're not even making the same cords. Frustrating.

    A very very bad product

    I've been using the small cable to link to my main eizo display and some times using it to connect to my projector. Just before my second cable failed to opearate. A really bad quality product, although an expensive one.

    Does what is says it does

    If had this for about 4 month now and I haven't had any issues with signal or whatever. One thing i dislike is the laughably ridiculous price tag. Apple, how can a mini display port to dvi-d cost $30 ???

    Worked just fine

    I had read all of the negative reviews and was extremely concerned about buying the product, but I had a presentation to do so i really had no choice. The mini display port worked perfectly, I had no issues. I did follow the instructions mentioned in other reviews.... attach it with the computer and LCD off, turn on computer then turn on LCD. No issue..... Remember to set your display to mirror!

    works just fine

    If you own a 23" cinema display and have been using an older macbook and have recently upgraded your macbook, this is the device you need to plug your monitor in to your new machine. It takes 5 minutes at the most and works perfectly with the cinema display.

    snow leopard not supporting apple talk is another issue...argh!

    Pretty Sweet

    Only reason it doesn't get 5 stars is cause it's overpriced, works perfect with my old school Apple ADC 23" display that's hooked up to another ridiculously expensive ADC -> DVI Adapter

    Mix up causes problems

    For some reason Apple uses 2 different ports to be able to use an external monitor, what your computer has in it is the type of adapter you buy. This mini displayport to DVI looks different than the mini dvi port plug. If you buy the correct adapter it will work. The best way that I found to be able to tell which one to get is to search the Apple store for the Mini and look at the I/O ports on the back. The MIni has both. Just see which one matches your output and buy that adapter. Hope that helps.

    It DOES fit! DVI-D only though!

    For the benefit of people saying this doesn't fit... It's a DVI-D cable only!
    DVI-D is the digital only version meaning the pins around the flat style one aren't there. If your cable has these on it then it is a DVI-I cable used for sending RGB analogue signals... in which case just buy the mini display port to VGA!

    Works mostly

    Pro: I can plug my monitor into the card through the Mini Display Port so I can still have both monitors.

    Cons: There are a lot of times where either it doesn't work at all, the monitor rapidly cycles pixels on and off or the monitor looks like it has areas of dead pixels. Cycling the power on the monitor resolves the issue most of the time, so it's more of an annoyance. I tested both of my displays, it's the adapter.

    Perfect

    I connect this between my MacBook Pro and a dvi to dvi lead which connects to my 20'' widescreen Samsung HDTV. No problems at all!

    It seems that if you use this to connect to the iMax cinema screen it won't work, but then it doesn't connect to my dishwasher either...

    Works Great... For Awhile

    I had mine help connect my macbook to my Samsung, but after a couple of months, the adapter stopped working, and I had to go buy another one...... Wish it were cheaper...
