Just installed Lion.

Running a second display.

The 'full screen' function doesn't work on the second display.

What happens is, clicking 'full screen' icon makes the app window go back to the main display.

Clicking again to make it 'usual size' sends it to the second display agin.


So full screen doesn't work on a second display.

Lion, Mac OS X (10.7)

    This is seriously bugging me too. Like many others I know, one of the reasons I bought Lion was because I would always have some app stretched out on my second display, but the control over it was pretty limited.

    Was really looking forward to the one-click space/fullscreen function, but after getting into the system I see that a second display is pretty much useless now. If Apple think they are going to shift the most expensive 27" display on the planet with this hiccup in 10.7, they've got another thing coming.

    That's bad news for users of classroom computers who use the Mac display while sending a presentation out to an external projector.  If it's application specific, there is hope so long as the developer doesn't follow Apple's implementation of full screen in Lion.


    One step forward... two steps back it seems.

    I'd also like to register my outrage at this very important feature for those of us who use external displays.  Come on!  What use is having two monitors but only have one of them full screen at once and have one of them show absolutely nothing?

  • Patrick Ellis1 Level 3 Level 3 (750 points)

    I cling to hope that Apple hasn't fully implemented full screen yet and that better control will be forthcoming.  That said, I also used to believe in Santa Claus and the Easter Bunny!


    Seriously, it is an issue for those who use multiple screens - It's reduced functionality.  This is one of the (multiple) reasons why I've recommended against upgrading to Lion at my work place.  We can't stop our students from using it on their own laptops but if they do, they'll have to live with mirroring mode when they hook up to our classroom projectors. 


    I recently screened our students' video work for their 'End-of-Year' festival directly from my Snow Leopard Mac using QT Player X in full screen on the projector while using my built-in display to monitor it and the system.  No longer being able to do that will mean I will be sticking to SL at work for some time as well. 


    I'm hoping this is properly addressed soon...

  • ronfrombantry Level 1 Level 1 (0 points)

    Yes this is ridiculous.

    I have a 13" MacBook, with a 22" display plugged in.

    Under SnowLeopard I could have Aperture running in fullscreen mode on the 22" with anything else on the 13".

    Now I just get the 13" screen and a blank 22".


    Also, in Mail, you used to be able to see the full headers if there was any query or problem.

    Now that option has gone.


    How can I get back to SL, it was much better.

    I noticed the same thing too with Quicktime.  What the **** is the point of plugging in a 40" TV (that worked perfectly with SL) so that I can watch movies on my 15" MBP display?  Quicktime has always come second to VLC, but now it is literally useless.

  • Tilly111 Level 1 Level 1 (0 points)

    Yes, same here.  What a disappointment for those of us who have invested in external displays. Surley, this will be remedied?

  • Patrick Ellis1 Level 3 Level 3 (750 points)

    In this case, it's appears less a QuickTime X issue and more a Lion, full screen issue.  Full screen needs work.

  • WilliamChanges Level 1 Level 1 (0 points)

    I think I found something! Make sure that whatever program you're using is the one you're clicked on, (iTunes), then try Command+T. I don't know what that command is supposed to mean, but it brings the program in use to fullscreen on my external display.


    Hopefully this helps!

  • PastorWynn Level 1 Level 1 (25 points)

    No, that don't work for me.

  • PastorWynn Level 1 Level 1 (25 points)

    Well, this is my first complaint about Lion.  I agree.  What is the point of the external monitor on my MBP 15" if, when I go to full screen, it shifts the app back to my MBP and leaves the monitor blank?  Sounds like the tech guys @ Apple need to address this quickly.


    Otherwise, I love the upgrade.

  • ronfrombantry Level 1 Level 1 (0 points)

    Command+T just brings up the text inspector.

    if they support having different mission control for each monitor, I think it would fix it. Imagine being able to mix and match your fullscreen apps independentlly in each display. I too am flabergasted at how fullscreen works ATM.


    If you NEED your fullscreen app in your second display and don't care if you see it in your main display, then you can go into display preferences and make the main window your second monitor by dragging the toolbar to the new display in display arrangement.


    you can also mirror your displays if you need to know what's going on in the other screen in a classroom environment.


    This is still not a solution because the second screen becomes useless. I would definitely use the new spaces/mission control if each monitor could scroll through it's own set of fullscreen apps/desktops.

  • Dan Connors Level 1 Level 1 (0 points)

    I find it kind of strange, too, and look forward to the fix, but I think there is a workaround: just do it the way you did it before Lion. Big deal.
