What would the the difference if I set my dell e773c to 75hz from setting it to 85hz?

Dell recommends that you set it to 75hz. But I was wondering whats the difference between if I set it to 75hz from setting it to 85hz. Ok so my question is: What would it look like if I set it to 75hz and if I set it to 85hz and which one do you think I should set it to?What would the the difference if I set my dell e773c to 75hz from setting it to 85hz?I doubt it matters since it's a small amount and won't matter much. Listen to Dell since if the computer is somehow destroyed, you will be surprised how this small detail of setting your PC to 10 hz more than recomended can affect you in court.
