Full system specs please...
And try with different monitor, if it still occur then your monitor is broke.

If it is a laptop, I hope you purchased accident insurance for it. As WA1 indicated you can hook up a monitor to it, if it just a damaged screen and still use it. If the screen is damaged you will have to get a replacement screen. What is the model number of your computer?
