Display dashboard full screen

I have made a dashboard specically to fit and be printed on one page.

However I want this to be displayed to fit full screen at the minute it isnt, is there anything I can add so that once opened it is resized to fit full screen?

Thanks, really appreciate your help

Sorry I mean is it possible to use VBA/formula to automatically set the zoom to fll screen based on range of dashboard;
Column (A:J) and rows (A1:A38)

Thanks
