I have a 2012 mbp 15' , I7 quad 2.6
and a vga only ,flat LCD screen .
Usually when the ext screen is connected (via minidisplay to vga adapter ) the system preferences displays dialog shows the name of the ext screen and the right screen resolution.
sometimes while the ext screen plugged in and the computer wake up from sleep mode the dialog shows "vga display" and not the display name and the screen resolution right option is unavailable .
the only fix for now is just replug the adapter
any thoughts ?
