I have a Macbook Pro with 3 LCD monitors & a 32" LCD TV connected to it as my monitors. I have the 3 LCD's on my desk set to extend the desktop, and the TV set to mirror my middle display. I am using 3 USB to VGA adapters to accomplish this setup. Prior to the OSX 10.8 update, my existing adapters worked great.
Now whenever I undock my laptop at the end of the day, or even restart it, the arrangement of the displays is altered in a completely random manner, and the resolution on the TV is different every time as well. It will also not power on with the correct mirror settings.
I have since purchased 3 new adapters that are compatible with OSX 10.8, but i still get the arrangement issue upon restart/ undocking.
If there is anyone out there who can help, i would greatly appreciate it.
