blue line on the screen

Sometimes a vertical blue line appears on the right side of the screen and it disappears minutes after the device turns on.
Please help and advice.

Re: blue line on the screen

It might help to know the model of computer, OS and if you could include a screenshot. Is it there before boot? At what point does it disappear?
