I can not get my second display to work
HI i have a mid 2010 mac book bro 13", I had it connected to VGA display and now it doesnt display anything or identify the second screen. This happened over night. please help
MacBook Pro, Mac OS X (10.7.4)
Maybe the VGA's power supply failed. I've gone through many VGA's where that happens (bad luck?).
Does your vga have a power switch that lights up? Can you feel any heat above the vga monitor? If yes to all of this, check your connections.
Note, these things are not cost effective to repair. Just get a replacement or a flat panel monitor.
