Trouble getting the program to show from projector to the hitting screen

"are you extending or duplicating your image." Iam sorry but I don't understand what that means. I get the image of the desk top on the hitting screen and even if I click on another icon and fill the computer screen with something else, all I see on the hitting screen is the desk top image. It doesn't change. Did that help any? And thank you for replying to my post, this has me going crazy!

Hello I need help. I hope I can describe my problem well enough to get some direction for my sim. I have an Optshot 2. I have it connected to my lap top and a flat screen TV. I have built a 10 x10 x 10 frame and have a hitting screen hanging at the back. Everything works great with this set-up. I just bought a 3M DMS 700 short throw projector so I can move from the TV to the hitting screen. Now the problem. All I am seeing on the screen is the desk top image. Even after I run the Optshot program I just see the desk top image on the screen. I have tried to start the program before I turn on the projector but that makes no difference. I can disconnect the HDMI cable from the projector and connect it to the TV and it works fine. My question is how do I get the program to work on the screen from the projector? Why does it work from the computer to the TV but not the projector?
