Any Photoshop gurus around?

Hi there, need help to find out how to set Photshop's workspace to accomodate to widescreen. My old (more like ancient...) pc 4:3 screen died a few days ago and I have replaced it with a widescreen. Predictably now all pics are shorter and stubbier (either that or everyone has put on some weight!), which makes editing awkward to say the least. Is there somewhere within Photoshop where one goes about setting up the workspace to counter-balance the distortion??
Thanks for any help!!

Are you using Windows? That's a function of the Display Control Panel. Adjust SCreen Resolution -- choose Advance Settings.

You'll need to know the display size your new monitor is capable of showing.

Thanks J. Just to clarify... Is that within Photoshop itself or within Windows contol pannel? Thanks again!
