Dual Display problem

Recommended Posts

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" :unsure: 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.

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.

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?

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.

Try to connect with other Computer with Screen Sharing (VNC), turn the mirror off remotely.

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.

I've even just done a fresh re-install and im having the same problem. I tried opening the terminal program on the desktop but I keep getting errors when I type each line and hit enter! I've repaired disk permissions, the lot! Im completely lost! Any help would be much appreciated! Thank you :)

i am so eager to try those commands when i get home, my screen doesn't action up when i click on detect display, it just goes blank (both screen, laptop and external monitor), so but i am gonna vnc onto my laptop and see if i can type those commands and get the windows working

 

jooby is that what you did?, both screens goes blank/acting up, so you vnc onto mac, from another pc, you get a nice screen, type those comamnds on terminal and get things working?

 

god I've been trying to make dual screen work for ages now, hopet his fixes it
