I have a mini DVI to VGA adaptor.  I use it to run PP displays off of a projector.   Shouldn't I be able to use the same adaptor to watch a movie from the MacBook Air through my TV which has a VGA input?  What I am getting is a second screen for the MacBook Air, and not a dedicated screen to watch the movie.  Am I forgetting to switch something from system preferences?  I went to display there and there didn't seem to be any option to do this.

    Hi Tylden,

     

    It sounds like what you need to do is turn "mirroring" off and use the extended display.

    See the article below for more information:

     

    How to use multiple displays with your Mac

     

    Hope this helps ...

    It's the reverse. You want the TV to be the same as the Mac's screen, so that when you put iTunes to full screen that's what you get on the TV. This is the default condition, at least on Snow Leopard (I've done it a number of times and have never touched the settings); if you have set up Extended Desktop you should turn it off.

    Hi Roger,

     

    Since Apple became the center of the known universe, I'm never 100% certain if I'm in the triple-bullseye of the precise, politically correct forum/thread/discussion. It seems as if I need to pursue a Doctorate Degree in https://discussions.apple.com protocols in order to determine the proper (oft-micromanaged) microcosm within "The Community" to pose a civil question. You present as a true gentleman, however, so I'm going to go out on a limb and hopefully, it won't get chain-sawed out from under me.

     

    If I may ask, seeing that you are running under Snow Leopard -  as I am; did you upgrade to iTunes 11.0.3? Any advice regarding the subject besides the obvious, do a back-up first would be greatly appreciated.

     

    Thanks in Advance,

    Michael

    I'm using iTunes 11.0.3 (which runs fine on Snow Leopard) but this isn't actually relevant because what you need to do is to mirror the Mac's display on the TV, so that whatever program you are running - iTunes, a game, or just a web browser - appears on the screen exactly as it does on the Mac.

     

    The additional display facility was originally intended for a second monitor, where what you want is additional Desktop space, but at least on Snow Leopard the default is mirroring. I don't know whether this has been changed in later versions.

     

    I use the mini display port to HDMI adaptor (though I can't see that the results would be any difference with the VGA adaptor). It 'just worked' the first time I plugged it in - the set picked up the screen, and when I played a movie it appeared on the TV just as if it was a broadcast.

    Actually, you can use either display mode - mirroring or extended desktop.  The benefit of using extended desktop is that you can take advantage of the higher resolution of the TV.

     

    The current MB Air can only display up to 1440x900 on its built-in display panel and if you use mirror mode the TV will be limited to the same resolution as the Air's display.

     

    If you use extended desktop mode, however, you can go up to 2560x1600 on the TV.  This is probably more than your TV can display, but it at least gives you the ability to do full 1920x1080i/p HD on your TV.  The trick is if you use extended desktop mode, you have to move (drag) the iTunes or browser window over to the extended display in order to view it on the TV.

    That makes logical sense: I've only ever done this with SD material so the default works well enough. Evidently the OP has done the first step but not the second.

    Yep, that's what it sounds like!

     

    iTunes and Netflix movies look great in 1080 HD on my Sony Bravia HDTV, connected to my MBPro as an extended desktop.
