I WILL BE PLACING MY PJ ABOUT 10' FROM THE SCREEN USING THE STANDARD FRESNELS AND 80MM LENS. WHAT SIZE IMAGE CAN I EXPECT. I NEED HORAZONTAL AND VERTICLE MEASUREMENTS NOT DIAGONAL. I WILL BE USING A 15" LCD.
THANKS
Full Version: HOW FAR FROM THE SCREEN IS YOUR PJ?
Mine is 10' from the wall also with the same 80mm lense I get a picture size 7"x9' so it will be big anought
corection 7ft x 9ft not 7in
I have mine 11 feet from the screen, 110" x 84" or about 132" diag. this works for me. I am using the standard lens and fresnels from LL.
