To get web browser full size in python bokeh

I use Bokeh to plot some interactive charts for my project, the Bokeh app runs on server. I like these charts can be plotted in full size on clients' browsers no matter what local resolution would be. Could someone give me a clue on how to get remote screen's max size?

1. I tried selenium, which asks user install drivers on local computer. It is not a good idea.
2. Also I tried python win32 API, which gets server's not remote computer's resolution.

Thanks
