Q: Macbook Pro and Vga projector problem

Ok this is probably an easy question for someone clued in on apple tech.

 

I have a macbook pro 15 (2010)  I connect to my classroom projector via a vga cable to the mini-port on the side. When the projector shows the picture it is not what i want to show, but a blank homescreen. If i go back to my macbook and drag the document or movie all the way to the right, so it is off the screen then it shows up on the projector screen. After it shows up I can use it, but have to use if from the projector screen as I can no longer see it on my computer.

 

Have I messed up my settings, or is this normal. I would just like to plug the projector in and see what i see on my screen on the projector screen, at the moment I can choose either edit on my mac but the class can not see it, or edit on the projector which is hard as the mouse is on the mac.

 

Can anyone offer a suggestion

 

Many thanks

    I know what to do on a PC but not a macbook. Basically it sounds like your display is extending to the second screen, not duplicating (meaning what you project and what you see on your mac screen are the same)

     

    Try to poke around in the set up slideshow or display settings of your program (keynote?) and see if there are controls for extending or duplicating the screen.

     

    What program are you using? If there's a forum for it I can ask the hosts to move this to the specific forum and see if it can get you a more precise answer faster. Or we can just get them to move it to the macbook forum.

    HI

     

    Thanks for speedy reply and your answer. Actually it doesn't matter what programme I use VLC for videos or word for mac, they all do not appear until i push them off my screen to the right hand edge of the screen then they appear on the projector screen. Once there I can click full screen and its ok, but not for word docs etc as i can edit while looking at the screen.

     

    Tried poking around in display settings but doesnt seem to be anything there I can change.

    thanks a million for trying

    You might also try Command-F7 (or fn-Command-F7).

     

    Depending on what version of Mac OS X, the System Preferences -> Displays control panel may have a "Show Mirroring opitons in Menu bar when available" check box.
