What kind of monitor? You may be faced with some out of range problem
You have to tell us more facts.

We also need to know a bit about all your hardware.
Run " lspci " in a terminal and post here (to avoid misunderstanding - the first character is a minor L and you copy by marking with the mouse and then right click)
Also tell us if this is using mint4win or not, quite important
This is a standard answer so it may not be fully applicable to your situation
