Does anyone know if it's possible to switch the primary and secondary view between my main and second monitors? I have a really nice 24" widescreen monitor as my main display and an older 19" monitor as my secondary display. At the moment I get to view all the browser etc. on the main monitor and the full screen preview is on the secondary display but it would be nice to swap this over, is that possible?

Aperture 3 just in case that makes a difference!



Mac Pro, MacBook Pro and PowerBook G4, Mac OS X (10.6.2), Aperture 3

    Yes but you need to switch it for your whole system. You can do that in System Preferences under display preferences.

    Really? Is that the only way? Don't have any desire to do that as it will mess up a load of settings for other apps. Thanks though.

    In fullscreenmode there is a "swap-Monitor" function.

    the use of multi display is really complex ... in that regard lightroom is way ahead .
    the solution i use is to swap display in full screen mode and to move by hand the HUD tool

    Until Apple releases a bug fix, Aperture 3 is unusable for me, so I've switched back to Aperture 2 for now.

    ••• But I think I have the solution for you, if you're using *Aperture 2*:

    • Go to full screen view (F).

    • You'll have a menu on top of screen, when you move your mouse there.

    • The 17th icon from the left looks like a little monitor (the hover help text display is "Viewer Mode").

    • Click on this and a menu will drop down, with the following options:
    Show Multiple ⌥U
    Show One ⌥R
    Three Up ⌥H
    Compare ⌥O
    Stack ⌥T
    Mirror ⌥M
    Alternate ⌥A
    Span ⌥S
    Blank ⌥B
    Desktop ⌥X

    I think what you're looking for is the *Show Multiple* and Span configuration.

    Try this or any other combination that will fit your needs.

    ••• In *Aperture 3*, according to the manual, the menu has a new option:
    Swap Displays ⌥S

    Which should give you exactly what you want.

    I hope this helps.

    Here's how I achieve what you want:

    iMac (read your 24" screen) as main in full screen mode and have the Browser on a secondary screen. To do this I have menus on Main screen, Main Screen set to Show One and Secondary Screen set to Desktop. I then resized the window in split screen mode (Browser and Viewer, no Inspector) and dragged it onto the Secondary screen, select a thumbnail and go into full screen using the HUD. Clicking the lock at top right of the HUD locks it to the right so it doesn't overlap the image. This does not work in Browser Only mode, as the full screen acts as a browser as well.

    I hope this is helpful.

    Thanks for all your help on this. I've had a play with a few of the options and they seem to give me what I need!

    LOL, how is lightroom "way" ahead? It's dual monitor implementation is terrible and doesn't even come close to the feature set. In fullscreen mode you can "lock" the HUD into position.

    Well, That kind of works but it is a pain to set up and the browser does not really work as it normally does. As well you cannot get to the real menu bar.

    Better than nothing, but I am amazed that this use case has been missed...
