Here is how you fix the vertical line problem on the macbook
restart by resetting the pram (holding command option p r on restart) until you hear 4 chimes
then when you get into os x. open up system pref.
go to display. change the resolution of your screen to anything but normal. then change back to normal. restart computer normally and problem is solved.

This absolutely did not work. Followed your directions exactly and nothing changed.
