Paween Posted August 17, 2008 Share Posted August 17, 2008 Please tell me how to disable mirror displays via UNIX command or edit preference files. I can't setup on connected external display because it fail screen. I think I have to change configuration on preference files. Link to comment Share on other sites More sharing options...

Kasakka Posted September 6, 2008 Share Posted September 6, 2008 System Preferences -> Display -> Arrangement -> uncheck Mirror Displays checkbox. The setting should be saved just fine. If you've set Mirror Displays but the dialog now opens on a second screen that for some reason doesn't show picture, disconnect the external monitor, then check the checkbox "Show display menu" option in Displays and you'll have a display icon in the top toolbar that you can click and turn mirroring off. Don't know if that'll help. Link to comment Share on other sites More sharing options...
BlackCH Posted September 7, 2008 Share Posted September 7, 2008 Actually 'System Preferences -> Display -> Arrangement' appears only after you connect the second screen, and if you selected mirror display setting (and didnt work; so basically you dont see a thing) it will load up right after you connect the 2nd monitor, and again you wont see a thing to be able to change the settings.... You could try pluggin another screen and see if that resets the dual screen settings, Another option is try playing around with switchResX. With this app you can choose the screensets in forehand... then load them with a keyboard shorcut or expose Link to comment Share on other sites More sharing options...
Paween Posted September 8, 2008 Author Share Posted September 8, 2008 Infact, when I connect the second screen, both of screen are flick. And then I can't setting anything.

daniborgs Posted February 5, 2009 Share Posted February 5, 2009 I have the same issue here and I found another solution. Actually, use SwitchResX seams to be the simplest way, but I've just forgot it... I use an AppleScript that open system pref. > displays > and uncheck "mirror display" (dono why I check this early...) Here is the link source [link]http://forums.msiwind.net/mac/how-you-turn-mirror-off-t6266.html[/link] and here is the code source: tell application "System Preferences" activate reveal anchor "displaysArrangementTab" of pane id "com.apple.preference.displays" tell application "System Events" tell application process "System Preferences" tell window 1 tell group 1 of tab group 1 click checkbox "Mirror Displays" end tell end tell end tell end tell end tell Thanx for remind me about SwitchResX is so cool!

pjmay Posted December 9, 2009 Share Posted December 9, 2009 Is there any way to leave the Mirror Displays box unchecked permanently? Every time I connect to a projector, it messes with my screen resolution and I have to uncheck the box again. Thanks, Patrick Link to comment Share on other sites More sharing options...
