    Mini DisplayPort Falls Short

    I am a first time Mac user and was a little hesitant. After purchasing a MacBook Pro I was very impressed and excited. I was so excited that I wanted to display this on my LG TV. My previous laptop did this with out any effort. So I went out to my local Apple store and picked up this little number. After I plugged it in and did a screen detection I was not able to get any picture. I called Apple for some trouble shooting. They were as lost as I was. I pulled out my e-harmony remote and forced the input setting on the TV to the RGB/PC. Low and behold there was my screen. It displays but not well. Falls short with the resolution settings. TV is 720p and I have to set the resolution to lower than this in order to display the full picture. When I do that iMovie and other applications will display bigger than what is on the screen and wont adjust any lower. I tried everything. The screen also goes blank and readjust frequently. Pretty disappointed. Love the Mac but Apple could of done better than setting the display port for only their products. Classic Apple.

    Have a backup computer for you presentation

    Because, like many here, I too have been unable to connect to several LCD projectors with this connector and a 15" MBP and a 13" MB. We tried two different mini display port to VGA adapters. Same results with each.

    Therapy for me to READ

    After years of debate, last week I approved purchases for our office to move to a MAC platform. Everyone has been raving about the new Mac Books....until we tried to use them in either of the conference rooms where HDTVs are located. Yeah, did not see that comming.

    Just wanted to point out, although it does not solve the MAJOR MAC BOOK ISSUE, it is nice to hear that it's not just our office plagued with this issue. APPLE, fulfill your legacy and fix this....please.

    Can Apple Help??

    Can Apple weigh in on this? I have a Samsung LCD and the VGA cable I have worked fine with my PC. Then I bought this when I got a new 13" aluminum Macbook and it doesn't work. Lots of people say it has to do with grounding pins on the VGA cable, but why does that same cable work with my PC? Why doesn't the Macbook work? Help!

    This adapter screwed a major presentation for me today

    Prior to january this year, I had never (10 years) had any problems with getting my Mac to recognize an external display. However, four weeks ago at a MAJOR presentation (research grant funding) my colleague's Macbook air failed to recognize the projector. Thank god we had brought my machine as a backup, and the presentation went fine. Today, the same thing happened to me at an important event. While we didn't lose money, it was _quite_ embarrassing to appear as a 10-year old who doesn't know how to connect a projector, and I had to give my presentation without slides (nobody else had Keynote '09 on a Mac). Apparently there are a number of people claiming this adapter either does not have all ground pins correctly connected, or that it has physical issues that prevents some VGA cables from sliding all the way in.

    This is a major issue right now, since there are no other miniDP->VGA adapters out there. For now, I would not recommend anybody to trust a new Macbook for a critical presentation - the next critical time I will play it safe with Powerpoint, just in case...

    Pathetic - re-syncs

    I upgraded from a $700 2 year old Toshiba laptop to a $2000 macbook pro 15". After buying this $29.95 part, I found that my monitor keeps going dark re-syncing.

    I also found my brand new bluetooth mighty mouse doesn't scroll up. Do I have to get an appointment at a store with a genius to simply do a return of the mouse?

    Freeze Frame

    With Macbook Pro (late 08), external VGA displays are basically unusable unless you close the lid. Otherwise, Video Res will be the same as laptops, and it freezes up if it goes to sleep or if you pull adapter out. Must also plug adapter in and boot, otherwise it freezes up. If you plug it in after booting, forget it.

    Very disappointing, wish Apple would fix this, otherwise the Macbook Pro is very nice...

    Don't buy

    It just doesn't work. Screen is waving, changing colors. Often I cannot even choose the resolution I want for my external screen. I've tried with two diffrent screens, and none of them worked good. This cable behaves like the worst Microsoft product and Apple pretends not to see it.

    Simply didn't work

    I bought this to hook up my new macbook to projectors. Tried to hook it up to a Dell projector and although the macbook seemed to recognize the display, the projector just kept displaying "searching for signal." Would love to find a solution.

    Very dissapointed

    I just bought a brand new mac book with this adapter hoping that I would be able to hook it up to the 23 inch samsung syncmaster 2333HD display I got for Christmas. The computer seems to acknowledge the monitor, having the correct name on the window when I hit "detect display" but the display will only read "check signal cable" the display works with other computers and even the vga adapter on my 2005 ibook. The macbook adapter works with my old crt external but not with this new display. This seems to be something of a trend based on the other reviews and I am very dissapointed. I'm going to try and see if the dvi adapter works but still, very disappointing. This is unacceptable.

    Just acquired a new Macbook pro (really nice bit of kit). Connected it to my Samsung 22" monitor via this converter. Now get the old blank sync screen every five mins. Makes me want to put my head through the screen. Is there anything I can do to fix this?... After reading the other reviews appears not. Please fix this Apple!

    Connects to my HP 24" LCD monitor. However, even at the highest resolution setting (which is native to my monitor) the picture is not completely sharp. I also experience the intermittent blackouts every 3-5 minutes. This is a major problem that needs to be fixed ASAP. Apple needs to get busy. This setup is unusable!

    Doesn't work with the Samsung LN46A550

    Rats, I wish I read these reviews before purchasing this adapter. I cannot get this to output to the Samsung.

    Absolute Joke

    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.

    Blinking monitor with my Mini DisplayPort to VGA Adapter

    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?

    unibody/aluminum macbook 2.4GHz

    AFTER purchasing the MB572Z/A miniport/VGA dongle with my new FB467LL/A macbook - the one with the "advanced" nVidia GeForce 9400M set, I read in the user's guide (p.66) that "Note: Your MacBook supports external display resolutions up to 1920 x 1200 on Apple DVI displays and up to 1600 x 1200 on VGA displays." Bullocks!
    The nVidia set supports "Maximum VGA Resolution 2048x1536".
    I can't fault this piece of hardware for Apple's lousy implementation of this "brand-new, industry-standard port". Or can I? Will I have to pay $50 for a "better" version of this later? I'll be counting the days I have left to RMA my macbook -

    monitor re-syncing

    I have tried this on 4 different monitors 3/4 would re-sync after around 5-10mins of use and then repeat. this gets extremely annoying when doing some work and your screen goes blank then turns back on in around 2 seconds.

    Beware - Certain Monitors Have Problems With This Adapter

    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.
