    DVI-I vs DVI-D

    The output is a DVI-D instead of DVI-I. So instead of carrying around one adapter I need two. This along with other issues makes me question the intentions of Apple's product line and feels like what happened in the 90's is happening again with Apple milking money out of users from the extra (or overpriced) hardware to buy. Interoperability is important.

    Frustrating. Works, but not as well as expected.

    I bought this device "just in case" I might need it. I never really used it, because I always had access to my desktop computer and never needed to use a separate display for my laptop. I got a new job where I'm on the road and working from a satellite office. Now, I figured, would be a good time to start using this device.

    The device hasn't completely stopped working, but it isn't very reliable. The screen image on the monitor frizzes up often. Think of an old school television antenna. The only solution is to jiggle and contort the adapter until a stable connection is made. Once again, think of an old school television antenna.

    So, I've owned the device for over a year, but the last month has been my first time using it regularly. I don't recommend that anyone buy this product. I've since ordered a similar device from a competitor. Hopefully the user experience is better.

    cuts out increasingly often

    I used it to connect my MacBook Pro to an extra display. At first it was fine, but then it started cutting out but could be temporarily fixed by unplugging and replugging it in to the port. Eventually, it got so bad that it would not come back on. I thought my Thunderbolt port was on the fritz, but I tried using a VGA adapter and everything was fine. (although I can't watch HD TV episodes on the external display.)

    Yes, it's DVI-D

    If anyone looks at the enlarged photos of this item they will see it has a horizontal pin C5 and a full set of pins 1-24. This means it is DVI-D, not DVI-I which has pins C1-C4 as well or DVI-A with C1-C4 and many other pins missing.
    If you do not check the connection before buying then that is not really Apple's fault. This is a very nicely made adapter and does the job well. The connection should be tight as there are some very dodgy DVI-D cables out there with poor screws on them.
    If you don't know what you have, then stick to VGA maybe.

    Works Well 98% of the Time. Occasionally Needs Unplug/Replug

    I got this with a new MBP in May of 2012. I plugged it in to my MBP and my plain old Samsung 22" digital monitor. It works reliably. Once in a while the display gets confused and puts the main screen on the Samsung when I wake up the computer. I unplug and replug (just once) and it works fine. I take my computer with me daily, so I plug and unplug this unit every day. Works fine.

    With some duct tape, this adapter may work reliably, or it may not.

    I got this adapter to extend the desktop of a new iMac. The two have now been attached for less than 3 years, linking the iMac via DVI to a Dell Ultrasharp monitor. After two years, if the cat walked by my desk, the Dell would black out. I checked the cables, changed cables, and figured out that the problem is in the connection at the Mini displayport. I finally started getting a reliable signal to the Dell by plugging in the adapter, pulling the adapter's cable up, against the iMac's back shell and duct-taping it in place about 3" above the port. In other words, this display port and its poorly-matching plug constitute a POS, in mechanic's jargon. I don't get it-the plug and its matching socket were developed by Apple (?), or at least both are built by Apple, but it's a lousy fit. That's unusual for Apple. There Will Be Duct Tape.

    Works with HP DVI monitors

    I bought two of these to hook-up to a pair of HP LP2065 monitors to my Retina MacBook Pro.
    External monitors each run at 1600x1200, works flawlessly. Can rotate the external monitors no problem via the settings in OSX.

    The material is solid and rigid and looks like it could take a beating.

    DOES NOT work with VGA (D-Sub) monitors. I tried a DVI to VGA cable, no output displayed to the external monitor. As expected though since there is only a digital signal coming out.

    Works as intended

    Recently migrated from a PC to an iMac and reused my 23" ASUS (VGA,DVI,HDMI) display as a secondary display.
    Connectivity and configuration was very easy and I have not encountered any problems to date.
    I am very happy with the purchase and ability to reuse a newer display device I otherwise would have had to get rid of.

    Doesn't work with DVI to VGA adapter

    I bought a MacBook Air. I bought this adapter thinking I'd be set, since I already had a DVI to VGA adapter (from the macbook pro I was replacing). However, the two aren't compatible. The DVI to VGA adapter has four pins which this doesn't accept.

    Doesn't work the way it should

    According to "Apples" FaQ Page on this adapter it is "Active" not "Passive" it isn't close to being Active because it does not work with a tripple monitor setup one has to be disabled for it to work. Great work Apple not... One unimpressed customer

    Does its job.

    I'm using it to connect my 13" MBP to a Viewsonic VX2450vm-LED monitor's DVI-D slot. Works well as its supposed to at 1920x1080 resolution.

    Ignore other reviews that gave this product 1 or 2 stars b/c they bought the wrong product.

    Does exactly what it's meant to

    I've used a couple of these for some time and they do exactly what they aim to do. It's true they don't do DVI-I analog, but I haven't seen a monitor in years that expects that.

    As some people have pointed out, the DVI signal out from a Mac is Digital.

    Apple seem to have missed out that vital detail in their description.

    color static issues on monitor

    I was not able to make this work between my 13" first-gen unibody MacBook Pro (I think early 2009) and 23" Cinema Display (2008 model). The cinema display showed red color static/noise all the time (and I tried several common methods for trying to fix that). I suppose this is just the price of older hardware, but would have been nice if they would play nice together.

    Apple Lack of Product Knowledge

    Buyer beware.. If you are looking to use this adapter as recommended by Apple for use with your Wacom Cintiq 21U it will not work. Even if you use the included dongle that came with your Cintiq to step the signal down to Analog DVI-I. You will need to purchase the Mini DisplayPort to VGA adapter, then a VGA to DVI-I adapter to get your state of the art Wacom display to function.

    I wish Apple would realize the difference between "State of Art" and "Cutting Edge". "State of Art" has the kinks worked out, "Cutting Edge" is nothing more than problematic.

    W.t.f. ?!?

    It's DVI-D, which means it does not support ANY commonly used DVI-cables of the analog type.
    Wow, so much money spent for a useless connector.

    Great apple fan up to now (iMac 27, Macbook Air, iPhone) but that really *s*u*c*k*s*! Congrats, bad work Apple! :-(

    Packaging totally misleading

    It's good to know that this supports only single-link DVI with a resolution of 1920 x 1200 or lower, which is _not_ written on the packaging, and not even on the description on the Apple Store. That's only once you've connected it between your Mac (e.g. a Mini 2011) and your monitor (e.g. a Samsung SA850) that you'll notice the max. resolution in the Displays Preferences, look for information on apple.com, and eventually find out the informative note hidden somewhere in the faqs.

    23" HD Cinema to 2011 MacBook Pro (15")

    If you want to connect a 15" MacBook Pro (2011 vintage) to an aluminum, 23" HD Cinema Display (about 2005/6 vintage or thereabouts), this is exactly the adapter you need. Also, yes, your 23" HD Cinema Display will continue to display in it's native 1920x1200 resolution. You can add a second display to your MacBook Pro or use it as a mirrored display. This is what I was looking for (2nd display for my MacBook Pro) and this adapter makes it possible. The only downside is that the adapter cable is so very short.

    Doesn't do 1920 x 1200

    Beware 30" cinema display users... this cable will not do 1920x1200. It will max out at half the native resolution: 1280 x 800. Check out dual link dvi cables.
