Hi,


First time getting a macbook. Great machine, but i still need windows. I setup bootcamp, and its worked great. Installed the macbook drivers and everything.

I picked up a minidisplay -> vga adapter and it works great in osx.

However, in windows i can not get the secondary display to work. I updated the drivers, still nothing. In the settings, i can see the secondary monitor, the brand of it and even the resolution of it. But nothing is on the screen.

I called apple, they referred me to microsoft, who referred me back to apple.


Any ideas?


Thanks,

2011 macbook pro, Mac OS X (10.6.6)

    I'm using a dynex (all that best buy had) but i dont think that would matter. Like i said, it works fine in osx.

    Which MacBook Pro do you have? Also which dynex model is it? OSX & Win7 video drivers are two separate pieces of software and function independently of each other.

    Glad to see this on the forums; I've been having the same problem for several weeks now. I usually wind up doing a restart. The only program that seems to be effected is Safari. I've tried updating the software but it's still happening. Any insight would be helpful.

    Got it solved!

    Called applecare again, and the guy told me that for some reason with that port, Win7 doesnt like analog. So i returned the vga and got a dvi adapter. Runs great now

    I still hope they will fix this problem .... otherwise how will I use a projector with the MBP whilst in Windows

    I'm also experiencing the same issue on the new MacBook Pro 13'' (Early 2011):

    Minidisplay->VGA connector works propertly from Mac OS X 10.6.7, but does not detect or does not output any signal to secondary display from Windows 7 SP1 (Ultimate x64). Bootcamp version 3.2 is up to date. I've tried updating to the latest Intel gfx driver (8.15.10.2321), but nothing changed.

    This looks like software compatibility issue of the Bookcamp. Switching from VGA connector to DVI connector is not a solution for me, since I need to use external projector from Windows, connected through VGA cable...

    Hope Apple will look into this issue and provide some fix/workaround, in place of just droping to Microsoft.

    My Macbook pro also has a same issue.
    I can not make a presentation for my business with Macbook Pro Early 2011! I do not want believe that Apple did not test just a projector...

    I have the same Problem.

    If I install the ATI driver for Radeon 6750m on Bootcam my external display stop working. Is clear a Driver roblem. I called both Apple and AMD. Apple said that is a AMD problem. AMD said that is an Apple problem.
    Basically - IF YOU NEED TO RUN BOOTCAMP WITH EXTERNAL DISPLAY DONT BUY THE NEW MAC BOOK PRO WITH ATI RADEON 6750M

    So conclusion is ....

     

    the problem is not limited to just the 13 inches Macbook Pro (which we initially thought it was caused by the Intel GMA video card)

     

    Looks like the 15 inch and 17 inch models are also having problems with the Mini Display to VGA cable while in Bootcamp.

     

    This is terrible .... I can't believe nobody is taking any responsibility to fix the problem ...

    I'm using the official cable from Apple .. it doesn't work either

    You can use extra display as a secondary display; choose “Extend” on “Connect to a Projector”.

    Hi nobuhiko,

     

    Just tried your method ... but it doesn't work. For some strange reason ... the VGA port is not detected by Windows 7 ... it just refuse to output (tried Duplicate, Extend, etc.)

    I tried 4 projectors with VGA adaptor from Apple and my Macbook Pro 13 inch early 2011 w Windows 7 works well with 2 of them.

    Is anyone in same situation?

    Or is any Apple who can resolve the problem?
