    It just works. Not

    • Written by from camberley

    I am a professional trainer I have been visiting customer's sites for over 15 years. Do you remember the overhead projectors and slides? I started with those...
    Since then I have used an array of PCs (Toshiba, Compac, IBM, Lenovo, Dell). I had never had a single instance where I was not able to connect to a projector and do a powerpoint presentation. Windows (95, XP, 7), Linux, it simply never has been a issue. As of late I decided that I should give mercy to my back by lightening the load I was carrying. I have met countless people raving about Apple products and I though to myself, if I was going to get myself a light laptop, I should use the reference in the matter hence the MacBook Air 2013. Without a doubt it is a beautiful machine until you try to connect it to a projector.

    I purchased the Apple MB572Z/A to connect to customer's projectors, in the space of 4 months I have been left without any ways of displaying my presentation 3 times. Needless to say when you are on the other side of the planet for a week and you cannot do your work because of shoddy design, you tend to get over sensitive about a piece of hardware that has costed you near to 2000 GBP (yes I god the support option bundled in).

    Being an electronic engineer by trade, I have done some extensive testing and here are my findings detailed for the poor souls who found themselves in the same situation than me.

    I am using the MacBook Air 2013 and I believe this is an essential point. I have purchased 3 different adapters the Apple one and two other brands. I also have done the test with a Dell PC using a display port too and finally I used separate cables of sort lengths and long length. It turns out it isn't directly related to the adapter but to the current that the MacBook Air has to drive on the Mini DisplayPort. Depending on the VGA cable impedance, the port had to drive more or less current. Regardless of the adapter used, my Dell can drive a projector using a long cable. When I use the MacBook air with the same cables as the one used by the Dell, The Macbook crashed and goes back to the login screen (requiring a PRAM reset). However if I shorten the cables, regardless of the adapter used or projector used, The MacBook had enough current to drive the signal.

    So the conclusion is rather a bitter one. It's a design fault on the internal driver logic of the MacBook Air. It is not able to cope with high impedance VGA cables unlike any other PC laptop I have ever used. So what is the solution I hear you ask?

    You can use the HDMI provided the projector is a new one, you can also take your own short VGA cable. However if you are like me and have to turn up on customer sites where the conference room have preset projectors (wall mounted) then you have to hope that Apple decide to acknowledge their engineering error and provide you with a replacement or maybe a buffered Mini Displayport adapter (I haven't seen any yet).

    I hope my misfortune/experiments will help some of you.

    Dissapointing...... No support for 1920x1440

    • Written by from Huizen

    Bought a new mac mini to use it with my home theater setup. Old mac mini with the intel graphics chipset can do up to 1920x1440 on analog VGA output. (via dvi to vga adapter). New setup with this cable can do max 1920x1200.... And even that doesnt work properly. Signals seem to be distorted....

    Waste of money.

    They Don't Last And They're Expensive

    • Written by from CONCORD

    I'm at a public school full of Macs. The preview adaptors lasted forever and were only 20 bucks. Now this one is 30 bucks and I've lost 3 so far this year. They just die. Not what you want in an public educations setting where funds are tight. Just a complication and they fall out...I could go on and on.

    It is not working for me

    • Written by from Buenos Aires

    This item is giving me a lot of headaches since I cannot get it to work with my new macbook... I have tried with 4 different monitors and at least 6 VGA cables and the best result that I got was a single day of trouble-free video, the first day.. after that it's been a nightmare and the monitors keep turning off and on, or not turning on at all.

    I've tried everything that I could think off: the firmware update (that is not working for me), software updates, restarting, shutting down, searching the forums for hours looking for a solution and even posting my own (still unanswered) question in the support forums.

    I wouldn't recommend anyone buying this product until the company comes up with a solution, there seem to be many people with the same issue.

    Useless under Boot Camp

    • Written by from Seattle

    I've tried to connect my MirrorBook Pro (2.53 GHz) to an external display under Boot Camp in XP, and then Vista. XP refuses to drive the monitor at any higher than 800x600. Under Vista it's even worse - max of 640x480. This was *AFTER* applying the Firmware update.

    Working on an external monitor was to be my primary method of using this machine, as the shiny screen is good for migraines and not much else.

    I have, no joke, 6 Apple video dongles that I've accumulated over the years. This is far and away the worst of the bunch, and the most trouble I've had trying to get a Mac to talk to a monitor, ever.

    Absolute Joke

    • Written by from orland park

    I just bought a new 13" 2.4GHz MacBook unibody along with this adapter. I was trying to connect my Samsung 32" LCD to my computer, and needless to say, the TV does not even recognize the MacBook. This is my first Mac, so it definitely leaves a sour taste in my mouth and doesn't give me too much confidence in the reliability of other Apple peripherals. This is an absolute joke-- frustrating and disappointing. I just wish I could rate this zero stars.

    Beware - Certain Monitors Have Problems With This Adapter

    • Written by from HAYWARDS HEATH

    I bought a new Alu MacBook back in November 2008. After a few weeks I decided to buy one of these adapters.
    Every 5 mins or so my screen goes black for 2-3 seconds before coming back on. This has been mentioned by other reviewers here but just wanted to add this is a common problem.
    I have called AppleCare and been into Apple Stores too many times. Apple do not appear to even acknowledge there is a problem! Look on Apple's own Forums and you will see the numbers having issues. I would stay clear until Apple fix the issue.

    Broke after less than a year

    • Written by from Evanston

    First it flickered a lot, and then finally it stopped working entirely. Have tested with multiple monitors, cables, and computers and it is definitely the adapter that is broken.

    One reviewer suggested that if we don't twist it, or leave it plugged in for more than an hour or two at a time, it will last. If that is the design specifications for these adapters, then the design specifications are wrong. Many modern professionals use their laptop as their primary computer. They plug it into their external monitor at the beginning of the workday, use it all day, and then unplug it and bring it home. When my workplace gave me a PC, I didn't even have to fiddle with cords; there was a dock I could trivially snap it into, and pop it out of. I didn't need a special dongle to connect it to a monitor, and I could use a monitor all day without difficulty. It is not unreasonable to expect to have that same kind of functionality in an Apple product, which is marketed as reliable and easy to use. I have to plug and unplug at least four things to dock my Mac. That's not easy to use, and it isn't reliable when one of those plugs keeps on breaking. Apple should be ashamed.

    Stopped working!

    • Written by from Richmond Hill

    Used this cable for a few months. Worked flawlessly. Big presentation day comes and I can't get it to work in client's boardroom. Red faced and frustrated I had to stand in front of the client and apologize on behalf of Apple. I was a PC guy and switched to Mac b/c of design and ease of use. Have to rethink that......

    Might not work between MacBookPro 8,1 and display LG W2353V

    • Written by from LEANDER

    LG W2353V (a 1920x1080 native) did not correctly identify through the "Mini DisplayPort to VGA" adapter, but *did* through the "MiniDisplayPort to DVI" adapter, when used with a new MacBook Pro 8,1 (early 2011).

    Using the VGA adapter, the W2353V only identifies as "VGA" and I am unable to use the higher resolutions. (I think "VGA" might be a fallback when it can't identify the device).
    I found a solution: Using "Mini DisplayPort to DVI" adapter instead (with a DVI cable) *worked* - I was able to test it because when I purchased my MBP8,1 I also purchased both adapters). The W2353V has three ports on it: VGA, DVI, and HDMI.
    I did also test using the "Mini DisplayPort to DVI"
    inline with a long Belkin DVI to HDMI cable I already owned, and that also worked
    with the MBP8,1:
    W2353:
    Resolution: 1920 x 1080 @ 60 Hz
    Pixel Depth: 32-Bit Color (ARGB8888)
    Mirror: Off
    Online: Yes
    Rotation: Supported
    Television: Yes
    .

    I do not know why the Mini DisplayPort to VGA Adapter is unable to identify this particular display.
    I do know that this same display works fine (gets recognized) by my older MBP 2,1
    using a DVI to VGA adapter of that same era. (That's an old full-sized DVI to VGA
    adapter by Apple, though, not this new Mini DisplayPort, and also talking to an older MacBook Pro 2,1)

    This testing was done with both MBPros (the old 2,1 and the new 8,1) running
    Snow Leopard 10.6.8 plus all latest updates (including firmware) through today (07/22/11).
    Hope this helps someone - who like me, is buying the latest MBP, and needs to
    use it with the same external display as the older MBP.

    Doesn't work properly!

    • Written by from Coimbatore

    I got this for my 15' High End Macbook Pro for connecting to my Samsung 23" monitor. Disappointingly it supports all the resolutions but does not support the native 1920 x 1080 resolution. The display is visible but the screen is moved to the sides leaving a big black bar in left of the screen.

    Blinking monitor with my Mini DisplayPort to VGA Adapter

    • Written by from Denens

    Dear Apple,
    I am fan of your products, but this is getting strangely disappointing.

    I have a 26" Benq monitor, and with my previous MB Pro it was already pretty complicated to synchronize it in full external screen definition. You needed a trick: put the Mac in standby, then open and close fast, etc...

    Now, with my new MB Pro and the Mini Displayport to vga adapter, not only you didn't fix this problem, but I am experiencing constant blinks (every 3-5 minutes).

    I have noticed that there are many other unanswered complaints regarding this matter.

    I am tired of searching for forums throughout the net; is there any way I can get a feedback about this?

    THANKS

    Burnt Out Within 9 Months

    • Written by from Denver

    I used this thing a lot and it eventually burnt out like a bad fuse. As best I can tell, all brands are equally worthless. I expected it to last as long as my macbook will, but it looks like this is just the beginning, and I'll be replacing these adapters until someone gets it right.
