    TERRIBLE PRODUCT

    • Written by from Hobart

    I bought one of these to connect my external monitor to my new Macbook Air. Got a blank screen on the external monitor, and the macbook did not recognize it at all. Confirmed that it was not working on my friends macbook. The one he bought elsewhere for $5 is still going strong after 6 months. This item is of very low build quality and the screws will not bolt into most standard DVI leads either.

    Doesn't quite make it with dell 30

    • Written by from Kailua Kona

    Resolution options peak at 1200x800 with mirrored option and 1680x1050 without mirrored option. Pulldowns do not show anything greater than that at each setting. The adapter is 30$ locally with 15% restocking fee. The more pricey adapter with the VGA and DV connectors has a restocking fee of $16. Although I could eat that if it doesn't work, I am not that hungry to have it.

    Be Warned - May Render Your Computer Unusable

    • Written by from Waco

    I ordered this adapter excited at the prospect of using two monitors for my work, putting my graphics software on one screen and my email etc on the other.

    Upon connecting the second monitor, my mouse no longer tracked smoothly. Every second or so it would jump, sometimes only an inch, sometimes clear across the screen. My computer is basically unusable when the second monitor is connected. This is a widespread problem I've found, with no solution except to use the VGA adapter instead. (It's on the apple support forums too.)

    I urge you, if you are interested in using two monitors, stick to the VGA!

    Works Fine

    • Written by from ATLANTA

    Prior to purchasing my i7 15' MBP I realized that was going to need this adaptor. It took 30 seconds to connect to my Apple Display and it has worked fine. It's somewhat of a pain to have to purchase two adaptors (firewire and dvi) but I'm over it.

    Incompatible With Cintiq

    • Written by from Cedar Rapids

    This adapter is not compatible with the Cintiq. I didn't bother reading the other reviews before purchasing it.

    It gets 2 starts because it looks really neat.

    Second Display with not turn on

    • Written by from Decatur

    Sometimes when the display that is connected to the Mini DisplayPort to DVI is connected nothing will be displayed. Most of the time this happens when the machine comes out of sleep mode. Unplugging and replugging does not work either. I have rebooted the machine and nothing seems to work. The screen will flicker when the second monitor is connected so it see it but no signal is sent to the monitor.

    Horrible Pass Through Quality

    • Written by from Los Angeles

    I've been using a viewsonic DVI monitor with my older mac book pro for a year and it was great. Very crisp and nice with DVI out to DVI in of the monitor. Now that Apple has switched over to the display port, requiring an adapter, it looks horrible. It is unusable for applications such as photoshop. And yes, I use the extended desktop display mode. Basically, whatever is going on behind the scenes with the adapter is just not working like it should, and they need to advertise such. Don't expect much from this - expect that you will be buying the LCD display that Apple has put out with the display port, much like I now have to. Thanks for forcing my hand, Apple.

    Solid Apple product

    • Written by from Fremont

    This might cost a bit, but it's top notch quality. The first one I got was defective, so I took off one star. But the level of professional customer support I got (I got yelled at when i went to Fry's) from Apple made me add one star. They tested the defective one, took out a 20" ACD and tried it. Then they gave me a new one, and opened it + tested it before I bought it. Fry's, Best Buys would have shoved me out the door. I know the later has done that before.

    Unreliable

    • Written by from London

    I've bought one of these and I'm pretty disappointed. I use it to connect a 2010 15" MacBookPro (8.2) to an ASUS PB278Q. Very often when I turn on the computer, the image in the monitor is completely grained (full of noise) and I can see the desktop below the noise. I need to unplug the USB part of the adapter (the power I suppose) and then re-plug it. Sometimes I need to do this twice. It may also work turn off and on the monitor. One thing is for sure: When I turn on the computer, or awake it from sleep, it's completely impossible to know whether the noise/grain will appear. Sometimes it does, sometimes it doesn't. I regret a LOT having bought this, specially because later I learned that I could simlpy have bought a cheap Mini Displayport to Displayport cable........

    If you can, use a DisplayPort cable instead...

    • Written by from Elmhurst

    I used this adaptor for quite a while.... Picture quality going from my MBP to my 22" Dell monitor was poor. Shadowing under text, blurry colors, etc. Completely unusable for the Photoshop work I needed to do. The Dell monitor when connected to my Windows PC via DVI was crystal clear.

    As a test, I bought a $10 DisplayPort-to-MiniDisplayPort cable and brought my MBP into the office and connected it to several 22" Dell and HP monitors we had with DisplayPorts on them... Wow! What a difference!!!! As perfect as you would want an external display to be!

    BTW - All of the monitors I tested against were priced under $200 - as was my monitor at home. They are noting but "average" monitors you would mass deploy in a typical office setting - they were not $1000 displays. So I do consider this an (forgive the pun) apples-to-apples comparison. The only differences between the units was the presence of a DisplayPort port or not.

    The only resolution I tested at was 1680x1050 - as this is the native resolution of all the monitors I have access to.

    No doubt to me - if you have the option of connecting via DisplayPort, then do so. While this adapter does "work", it does not work nearly as well as native DisplayPort.

    Make sure its screwed in tight

    • Written by from Slough

    I bought this to connect my Mac Mini to an eternal LG 27inch IPS monitor.

    It caused no end of flickering and screen blackouts and fuzzy grey screens.

    My solution was to make sure the DVI plug was screwed SUPER TIGHT into the adaptor and I mean super tight...tighter than I've ever screwed a DVI plug into any socket ever before....

    This solved all my problems.

    DVI only and tight fit

    • Written by from London

    It's a shame no RGB pinouts are available so if you ever want VGA, you need a separate displayport adapter (external DVI to VGA adapter is not possible).
    Also it is a tight fit especially with a DVI to HDMI adapter of mine.
    Other than that, it works without a hitch for me.

    Doesn't work with existing DVI adapters

    • Written by from Cedar City

    I got this hoping it would work with my existing DVI adapter for my old Macbook Pro so that I could hook it up to my TV, but no it's like 2 pins short of working. Maybe I should try to return it but it's more trouble than it was worth to buy it.

    Mini-Display to DVI on the package. Not DVI-D.

    • Written by from SAN FRANCISCO

    Ordered this, got it and it doesn't work with standard DVI. Have to spend more money buying the DVI-D cable. More shenanigans for Apple to make you spend more money on cables etc. Everything was great on MacBook Pro until this Unibody junk..

    Love It

    • Written by from DAVIS

    My MacBook Pro is connected through this adapter to a ViewSonic DVI port and my PC is connected to the ViewSonic VGA port, making it easy to switch the ViewSonic to show either machine. Worked out of the box, no problems.

    This adaptor does exactly what is says it does, 100% of the time. I use it for my Apple Cinema Screen at work and at home and it works every time I plug my MacBook Pro in.

    By far the worst thing about my macbook

    • Written by from Costa Mesa

    I absolutely hate the mini displayport. Have gone through at least 10 mini displayport to dvi adapters since purchasing my macbook pro. It doesn't matter if it is an apple cable or not. Horrible product that makes running multiple monitors an incredibly frustrating experience. I teach and cannot rely on this to use in my class so instead of being able to take my laptop with me (the whole reason I bought it in the first place) I have to leave it at home and email my presentations to a campus computer. Really cannot express how much disdain I have for this "product"
