I accidentally bumped my MacBook Pro and now I have several lines on left and bottom sides of the screen.
The effected area is usable but hampers experience. I would like to somehow restrict the output to the working area of the screen.
I remember CRT monitors used to have features to easily, stretch/skew and position output.
How can I do this in OS X 10.10, Yosemite?
Either a built-in feature or a third party application would be welcome.
