Hi everyone,

I’m creating a presentation in Flash that will be projected onto a large screen. I’m using fscommand(“fullscreen”, true) to make it fullscreen. Since I don’t know in advance what type of playback monitor will be used, apparently there may be some issue with the monitor ratio not being 4:3 which would make it widescreen. I was told to make sure the animation etc extends beyond the Stage frame so that it accommodates widescreen but I’m not sure how to do this - I mean how do you know how far beyond the stage to extend things? Since I don’t have access to the playback monitor I can’t test on it and the presentation will eventually be put onto a CD ROM where viewers may have all types of monitors. So I guess the question is how can I be sure it’ll look correct on all monitors in fullscreen mode?

Would really appreciate any advice.

Thanks
