Solved! i cant change my laptop refresh rate.. stuck at 60hz

Jul 16, 2019
i ordered an asus gl502vsk 7th gen gtx1070 ,and it was advertised as a laptop with a 120hz display.. to my surprise, it wasn't at all i was stuck at 60hz and couldn't even change the refresh rate no matter how hard i tried and searched for a solution .. i feel mislead and like ive just wasted my money on something i don't want.
