When i unpacked and set it up (which was easy to do) I turned it on and could not get a Clear picture on a white movie screen, that i use for other projection camera, more than 2 feet way from screen, I thought maybe there was protective plastic on leans i missed there was not, the focus knob turned as far as you can both ways and I get a clear picture that is maybe 25 inches wide. after that blurry. I tried on a white wall, the screen it came with. and it is not a clear picture 25 inch
