Monitor issues with alignment.

Last night I was sitting at my computer and the monitor flickered and the alignment got messed up. From 1 side of my screen theres a tiny black bar that goes to the other side diagnoly down and part of the desktop is not shown. Also there is a drop shadow of multi-colors on everything that shows on my desktop. Usually I would just tap the side of my monitor and it would usually fix but currently it hasn't. I was wondering what kind of issue this is.
