How can I change the size of the button in Adobe AI CS?

I can't see the button clearly and my notebook is surface book. The display is 3000x2000. Please help me. How can I get a larger button?

Are you talking about a button that you drew and is invisible or the interface of Illustrator?
I am going to assume the latter, and the only thing to do is to change the resolution of your screen display.
And by surface book, do you mean Surface Pro?
