So, I was trying to use my Hackintosh 10v on an 18" monitor. I made the mistake of clicking mirroring on, and the screen went crazy and wouldn't refresh. Is there anyway to turn off mirroring without plugging in a monitor?

I fixed the same problem by downloading a command line tool and using following the instructions here

Hope this helps!

Alternatively when the screen is all messed up, enable Voice Over (command-F5), and navigate your way to the top menu, then follow voice prompts to get to "displays" (you need to enable "always show in menu bar" in display preferences) and to disable display mirroring in there.

There's a much easier way to fix this than the command line or Voiceover (although they will also work). Download this little app called MirrorDisplays. All it does is switch to Mirroring and Extended desktop when run. Put it in your Applications folder. Whenever you get a messed up screen, hit Cmd-Space for Spotlight (or Quicksilver), type "Mirror", and hit enter. This should fix it immediately. The reason this works is when the screen is messed up, the OS is running just fine and you can toggle anything like normal. ^_^

NBI actually has this built in to it.

Go to /Extra/bin

You can turn mirroring on or off by issuing the following commands:

mirroring on
mirroring off



You can just leave the terminal open with the commands of on/off ready.....test it......it WON'T work....haha......but once you realize mirroring will not work, just click on your screen to activate terminal, and hit enter so the 'mirroring off' command will be executed.....good to go.

cheers.

@browndogfred0215 that actually *DID* work. and was totally easy! thanks for that!

[browndogfred0215]

Excellent. Thanks to Meklort for adding that into NBI.

I open terminal.

Change to /Extras/bin. (cd Extras . cd bin )

If i type 'ls', i can see 'mirroring' and 'netbookInstallerHelper'.

But if i type 'mirroring on' or 'mirroring off' in the terminal, i get the message:

-bash: mirroring: command not found

Any ideas???

Another alternative would be to make mirroring work...

Vga out on 10v with osx

cd /Extras/bin
./mirroring on
./mirroring off

Notice the use of "./" before the "mirroring" command, as that is important.
