Full Screen viewing is available. To get into Full Screen mode, move your mouse over the video player and the player controls should appear. Click the icon on the far right in the player controls, which should expand the player to full screen.
When in Full Screen mode you can exit by clicking the icon again. The player control bar will disappear after a few seconds once the mouse has been inactive. To get the player control bar to re-appear just move the mouse. Another way to get out of Full Screen mode is to click the ESC key on your computer.
