    DVI drops Analog signal, DVI-D only

    • Written by from Gray

    We know the Mini DisplayPort can output an analog signal because there's a Mini DisplayPort to VGA adapter. So why does this adapter drop the analog signal and go strictly to DVI-D (Digital only) instead of DVI-I (analog & digital)? The old MacBook Pro's had DVI-I. So this adapter is not a replacement to what used to come standard on MacBook Pros! I'm left very frustrated.

    Make sure you get the right one!

    • Written by from Cardiff

    Usually Apple products just work, thats why they are so great. Things aren't as easy as you'd think with the mini DisplayPort Adapters though.

    The DVI version seems to be only for DVI-D (digital DVI) and not DVI-A (analog DVI), which is more common on older hardware. They are only compatible one way, as the DVI-A connector has some extra pins. Cleverly you can't even use Apples own DVI-to-VGA Adapter due to the extra pins. If you plan on using both and don't absolutely need the digital signal, get the Mini DisplayPort to VGA Adapter and a seperate VGA-DVI Adapter.

    So make sure you spend your hard earned wisely on this and check what inputs your monitor has. Unless its fairly new, chances are it will be DVI-A.

    I haven't had any picture related issues, but chances are the earlier reviewer has problems with the new NVIDIA chip and its not the adapters fault.

    2 Stars as should cost half the price for what you get.

    Problems with waking display from sleep

    • Written by from LONDON

    While it looks nice and neat, it gives me a problem with my Dell 2001FP.

    Every time the display goes to sleep it doesn't come back on without me having to unplug and plug it back in.

    Of course it could be the software but the same monitor worked fine for me on my old MBP.

    Two other points:

    It would be nice if the cable was a few inches longer so I could hide it behind the screen when I work.

    £20 for a bit of plastic? Only apple can get away with that.

    DVI-D, not the more-common DVI-I

    • Written by from Los Altos

    This adapter provides a DVI-D connection. Most DVI cables and adapters I've come across use a DVI-I connection, which has four additional pins on one side (above and below the flat, horizontal pin). This adapter physically blocks those four pins, preventing a connection. I ended up having to buy a special DVI cable (as well as Apple's VGA adapter) to make sure I could always connect to a projector or display on the road.

    Works but Too Expensive

    • Written by from London

    This seems to work well so far, which is relief after hearing about others problems. I have tested it with both my Cinema Display, Samsung TFT and cheapy video projector. It is a shame though that after spending so much and a very nice laptop we are forced to pay £40 to be able to plug it in to these very standard devices.

    Doesn't work with DVI to VGA adapter

    • Written by from Columbia

    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.

    Apple Lack of Product Knowledge

    • Written by from Georgetown

    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.

    Misleading Product description

    • Written by from Montreal

    I didn't realize this was DVI-D (digital ONLY) until I received it and tried to plug it into a DVI to VGA adapter. Way to put one over on your customers, apple!

    Be advised: If you want to use your MBP mini-displayport with a VGA monitor, you'll need a SEPARATE mini-displayport to VGA adapter. This one won't work with any other adapter.

    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.

    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.

    Sort of worked for a while

    • Written by from AUSTIN

    I purchased this DVI adapter for my Macbook's mini display port. It worked with an Asus 24 inch monitor for about three months and then failed. It would work intermittently when it did work. Sometimes it would output a signal and sometimes it would not. I recommend using VGA instead.

    Check it before leaving the store.

    • Written by from Boca Raton

    Unless you live really close to the apple store, I would ask them to check this on a machine in the store before leaving. Bought one today, bought my second monitor, hooked it up and nothing. Swapped cables, nothing. Called Apple Tech support, they had me do a few things, ended up back at the store. Tested my purchased one on their computer, nothing. Took another from the package, nothing. The manager allowed me to have one more, but could not test it there. 18 miles later, it works.

    Seems like a shame to have to get an adapter for a dual port video card, but $29 is not bad after spending money on the Mac Pro.

    Plug is poorly designed - needs improvement

    • Written by from Portland

    It functions fine for connecting a monitor to my MacBook, but the build quality is not what I expected from Apple.

    The second time I used it, while trying to remove the the mini DisplayPort plug from the computer, the plug's outer sheath slipped off the "innards" of the plug, which remained in the port. I managed to work the sheath (almost) back into position, which is only press-fitted into place. It is difficult to thread the cord's strain relief back through the plug sheath.

    It would be nice if the cord were longer, so I could stash the big clunky junction with the dvi cable behind my desk.

    The smooth shiny finish of the tiny plug also makes it hard to grasp but that seems to be an Apple design paradigm. (I have the same beef with the mag safe connector.) Cmon Apple, you could do better.

    Incompatible with my 21" Wacom Cintiq

    • Written by from Morgan Hill

    My $2000 Wacom tablet uses DVI-I, and this cable is DVI-D. My brand new Macbook Pro (unibody) can't connect because of the pins. BE CAREFUL and check the pins on your hardware before buying this.

    Deceptive Packaging, Downgrade

    • Written by from New York

    The package only says DVI. Now granted the baggie is clear and you can see the connector itself, but when buying a new Macbook Pro, I just asked for the DVI adapter, thinking it was as good as the previous DVI output on my last Macbook Pro. Why would Apple remove functionality from a product, right? I mean having to use an additional adapter (and not have it included with the computer) was bad enough, but why would the new adapter not support DVI-I, when all the previous ones did? Especially given that there appear not to be adapters for MDP that replace the ones available for the previous generation. I see none for S-video or RCA-out. I still need to be able to connect to all these things, not everywhere I go has modern video technology.

    I understand the decision to remove the full-size DVI port from the unibody models, but not to fail to adequately replace it with the adapter. And then put a generic label on the adapter not indicating it's less compatible than what it's supposed to replace.

    Oh, and I should mention, mine actually doesn't work at all. I think it might just be a defective unit, but I don't have another DVI monitor to test with right now.

    does not work with apple DVI to RGB converter

    • Written by from Gateshead

    I bought this along with my new macbook, thinking that I could connect my VGA monitors via the old apple DVI to RGB converter that came with my mac mini. It does not work, as the old converter is DVI-I and the new converter is DVI-D. How frustrating! As others have pointed out, why on earth doesn't apple provide a DVI-I connection on this adaptor?

    Not Compatible With Many Displays

    • Written by from Somerville

    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.

    wondering why your displayport isn't working right? think its broken?

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!

    DVI-D ONLY

    • Written by from Nashville

    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.

    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.
