When you say the image stretches out, does it also flatten at the same time? If so, then it's definitely time to replace the monitor, unless you really do want to see it blow
I'd let it blow. One of the computer's monitors in my school's ICT suite did the exact same thing, no one bothered to fix it and left it on, randomly in the lesson it just exploded out of nowhere. If you don't want to get hurt get a new one.
