Dual monitors and fullscreen fiasco, is there a work around?

If you have a dual monitor set-up and Lion and you have tried the fullscreen setting, then you know what is wrong.


Might as well not even have the second monitor...Lion completely takes over both monitors and only allows you to have one app up. Pointless, and no way to stop it. (A preference setting in System Preferences under Displays would have been the right thing to do).


I know I don't have to use fullscreen, but it was nice to be able to view a Quicktime movie fullscreen on one monitor while continuing to work on the other. Lion makes that impossible.


Anyone know of a work-around or fix for the fullscreen/dual monitor fiasco?


Thanks for all help.

I just have to put my say in there. This no multiple display full screen business is total crap. I don't know anybody that likes it. As a developer who works mostly from the terminal and in a browser window, I'd really like to fullscreen chrome in one display and iTerm2 in the other and just shoot my way around the OS with keyboard shortcuts, but I'm stuck with the chrome tabs and address bar and the apple taskbar taking up unnecessary space at the top. A lot of the developers in my area have just waved the white flag and gotten rid of their second monitor.


I don't know what Apple was thinking when they made this design decision. I can see where this would be a pain for graphics designers who want to have their editing tool on one monitor and their video on the other. Web developers want their coding environment on one display and the browser on the other. I'd imagine mobile developers would want the iOS virtual machine on one monitor and their coding environment on the other. The average user I'm sure would benefit from being able to have something up on the second monitor, as well.


Apple, I like OS X, but this was a pretty bad design. Fix it in the next release.

I read about what will be introduced with Mavericks after I posted here. 100% approval on the multi-display in fullscreen support 😀. I guess there are some people that won't like different spaces per monitor, but I sort of prefer that DWM-ish behavior.


Now, if only I could have a tiling window manager like DWM or XMonad... but THAT is picking nits.

To me, the full screen mode is still broken in Mavericks. My setup is dual screen, 30" + 24" rotated. I have my programming IDE on the left 30" and a testing Chrome browser on the right 24". But I also have GMail and other stuff on another Chrome window on the 30". I can't seem to cmd-tab to this window without manually exiting the full screen mode of my IDE. I just get to the right Chrome window on the 24" and if I try to cycle between windows within app, I no longer have the ability to go to another screen.


The rules seem to be: when cmd-tabbing to an app, only if there is only a window for this app on the currently full screened screen, switch away the full screen and show this window. So as long as I have a Chrome window on my right screen I can NEVER get my IDE to move away and show the Chrome window on my left. Borked.

What about Cmd-` to cycle between Chrome windows once that app has focus? That's about the only thing I can think of that might help.


Edited to add: *FACEPALM* I just noticed that you wrote "get my IDE to move away and show the Chrome window on my left". The IDE is on an entirely different desktop than the Chrome window. That's how fullscreen mode is implemented: The windowed app going to fullscreen switches to an entirely different desktop. If you view your desktops from Mission Control, you'll see your Chrome windows still sitting where they were, but the IDE in fullscreen has its own desktop all to itself. At least, that's the behaviour on Lion and Mountain Lion. My apologies if Mavericks has changed the fullscreen behaviour.

Yeah, the problem is that I can't get to my left Chrome window even if I try to middle-jump to the right Chrome window first. Trying cmd-´ (it's cmd-< on sv_SE though) just toggles between the Chrome windows on my right screen. It's like my left Chrome window never existed until I close down the full screen mode on my IDE.

That's because that key combination doesn't switch between desktops; it only cycles through the applications on the current desktops. And that's the problem with Apple's implementation of fullscreen for me: Putting an app fullscreen causes it to open a new desktop on which to display in fullscreen mode. When you exit fullscreen mode, it goes back to its original, windowed desktop and then deletes the fullscreen desktop from Mission Control.


All in all, not a very good solution. Sorry for your pain, and I'm sorry to hear that even Mavericks doesn't fix the problem.


Question for you: When you switch desktops, do both monitors change or is it only just the monitor that has application focus. I heard that Mavericks would decouple the extended desktops and treat each monitor separately. Personally, I hope that's not the case.

The answer is "it depends." It depends on whether your Mission Control option "Displays have separate Spaces" is turned on or off.


Personally I think the full-screen situation has improved greatly in Mavericks.

Thanks for the info. It confirms what I've read since the release. Apple apparently listened during the beta testing and kept it possible to continue using an extended desktop paradigm. Mavericks finally makes me want to buy a new MacBook. Good job, Apple!

Nice catch. Didn't notice this. Personally, extended desktops (the Mountain Lion behavior) make absolutely zero sense to me. Having each monitor operate as a seperate space is so much more conducive to my workflow. Now I just wish I could have mail go fullscreen but keep the ability to drag a reply window to a seperate space/monitor.

Dual monitors and fullscreen fiasco, is there a work around?
