Rotate entire powerpoint presentation vertically

[briancotrone]

Hi, I am using digital signage players to show my restaurant menus. I am using a powerpoint presentation to cycle through menus. The issue is that the tvs I use are hung vertically. I essentially need to know if it is possible to rotate the entire powerpoint presentation as you would an image. Not the slide orientation, essentially I need to view the presentation sideways. Thanks for any help.
