Make iMac remember monitor positions after restart I have an iMac with the following specs:





I have 2 20'' hp monitors that are always connected to my Mac. They are connected with 2 DisplayLink USB to VGA adapters. I keep the monitors positioned as follows:





Unfortunately, everytime I restart my Mac, the screen positions revert to the default settings of:





This is very frustrating. 

How can I make my Mac remember and reapply my monitor positions when I restart?

The obvious thing would be if the preference for your user that stores the setting is corrupt. 

To test this, turn off auto login, make a new user, log in to that user  and arrange the monitors as you like. Log out of the test user, restart the Mac and log into the test user. This will let you know if the system problem or if it's a user problem.
