How do I make a game or animation fullsize

How is this done?

For a game, you could (with your cursor in the 3D view) hit CTRL+UPARROW to fullsize the window.

For an animation, fullscreen your movie player I guess? Or render at your screen resolution :smiley: lol

No fullscreen as an exe.

Press F10 in blender, then under game frame settings, select full screen.
