Projector and widescreen

My projector project was created at 1024x711 size and looks great on all my computers. However yesterday I tried it in a friends system with a widescreen monitor and it completely stretched the whole thing out. I tried making several adjustments but no matter what I do it stretches the project across the whole screen, and this is not a full screen project. The window is scaleable and sizeable. Can I keep the projector from going widescreen somehow, or is this something to do with the display settings on the other computer? Thanks.

Depending on the version of Flash you're using you can set the stage scale mode or use fscommand("allowscale", "false") to prevent Flash from scaling your content no matter how you resize the window.

I figured it out. He had his monitor set at 1024x768 resolution on a widescreen, so my project was displaying correctly. His monitor was stretching it to fill the whole screen. Thanks anyway.
