I'm new to this message board, so I hope the pics come out all right, but here's what my vid first looks like...
and here is how it's suposed to look like..
I tried the contrast thing, and it wasn't the problem, and didn't know what to change the system preferences back to...but if I waited a while the computer would change back to normal....
thanks for ya'lls help, this is my first mac so I'm not sure what's going on with it.
