When I turned in my projector today it showed my computer screen but not the internet page that I was on. It was as if I never clicked on the internet , it just showed the chrome tab on the bottom of my screen but not the actual chrome page. Any thoughts? It worked fine earlier in the day.

What kind of computer do you have? I know on my mac, I can have the projector set to different settings, perhaps yours has defaulted to the wrong one.
(on mac - click on the apple, system preferences, display).

I know nothing about Macs, but even on a PC, there are different displays and different settings within Display.

Essentially, your computer recognizes the SB as a second screen. You need to choose how it is displayed--to mimic your computer screen or extend it. Sometimes even an accidental "flick" can change it accidentally.

I would start by double checking that setting and go from there. Personally, I leave mine on mimic the computer screen. I have tried to do the extended screen version and never liked it myself.

This just happened to me with a doc camera and projector connected to my desk top. I never even knew such a thing was possible! The art teacher actually fixed it for me!
