i got a new moniter and i cant figure this out. there is about half an inch on top and bottom that is not being used by the screen. i no that sounded stupid but hopefully you understood that.
look on the back of the monitor for some knobs for streaching if there aren't any on the front... you could download a program that mimics your monitors sizeing functions.
I have never come across such a program but if you can't find one then look for the monitors driver... it could have a software program that is used for the adjustments.
