there are a couple ways... first way, click on Layout 1 in the Project window on the right, then click on "View" by Project Properties over on the left side of the screen... look under Display, and change Viewport Size (default is 640x480)... make it 800x600 or whatever you want.
another way is add an action to event 1 "On Start of Layout"
add System - Set Layout scale to 0.5
that will zoom the camera out to 50%
