jooby Posted June 1, 2008 Share Posted June 1, 2008 Hi, I got 10.5 running on my lenovo 3000 y410 laptop running pretty decently. So I decided to plug in a second monitor and everything went well. But then, I went into the display options and checked "Mirror Display" and now both monitors start to flicker and display random colors. If I unplug the secondary monitor it flickers some more and then returns back to normal. I was wondering if there's a terminal command to turn off Mirror Display or some other work around? Thanks.

kpitstupidsimple Posted June 2, 2008 Share Posted June 2, 2008 I have a desktop with two monitors. One is WSXGA and one is WUXGA. When you use them in side-by-side mode, everything works great. I think OSX or at least hackintoshes have a problem with mirror mode on two screens of different native resolutions.

jooby Posted June 5, 2008 Author Share Posted June 5, 2008 Thanks. But I kinda figured that. I can't get the "mirror Image" Checkbox because I don't have the second monitor plugged in. When I do plug it in, both monitor start acting up. Any one have a solution?

jooby Posted June 5, 2008 Author Share Posted June 5, 2008 What I'm trying to do is turn Mirror Image off. But I can't because when I plug in my second monitor both screens get distorted and I can't see a thing. So thats why I'm asking if there is a way to turn it off in terminal or edit a certain kext file.

Krazubu Posted June 6, 2008 Share Posted June 6, 2008 Other way : Boot the terminal and type the following (replace "USERNAME" as needed, case sensitive) : rm -f /Library/Preferences/com.apple.window* rm -f /Users/"USERNAME"/Library/Preferences/ByHost/com.apple.window* rm -f /Users/"USERNAME"/Library/Preferences/ByHost/com.apple.pref* This will reset the display configuration.
