85hz is a pretty normal resolution. You could always try using the given "optimal" setting in the list of refresh rates. Your graphics card will give you a maximum refresh rate you can use depending on your resolution which you won't be able to choose higher than. I think drivers for monitors also give you the correct limitations too.
