how to change my PPD into full screen mode?

I'm new player of PPD and I don't know clearly about the settings.Is there anyone can help me?thanks a lot~

before turning on PPD, go to the KHC folder> PPD folder> PPDConfig> then the Full Screen button and ok. This will cover your entire screen so if you want to exit PPD you can, 1) press the space bar and then exit. 2) press ALT + Tabs. number one works best in my opinion :D

Thanks a lot~
