Aoc 2036S monitor is shaking? help?

my monitor is shaking and I cant edit the refresh rate, so if theres anything else besides going to bios any help would be appreciated. if there isnt just explain the bios a little bit so i get an understanding. im running a new alienware m11x, my monitor did not shake with my old gateway laptop so its kinda odd. its only shaking at the very top of the screen
