Make Flash larger on monitor?

[An Artist]

I put a lot of work in my flash website that will soon be launch. But now I realize I want it to fit better into the larger wide screen monitors. Is there a way I can make it larger without losing image quality? I know this probably needs to be done in the publishing tool. If anyone could help me I would greatly appreciate it.
Thanks
