Dual Display?

Im looking to get a new G5 system to run FCP Studio. Im am trying to decide on getting a single 23" display or two 20" displays. I was originally set on getting a single 23" just for the shear amount of workspace available, but my friend is trying to talk me into getting two 20" displays. I am used to working on a single 19" display for editing at work at the moment...what is the second display usually used for when editing video? Is it primarily used as a canvas preview or more workspace? Thanks!

I have to the 23 inch display but at times thought about the dual 20 inch instead. With that said I will tell you what I would have done if I got the dual 20 inchs..

If I were to have a dual 20 inch then I would have the timeline and browser and I would set up a workspace for that screen that would increase my productivity. Then I would set up a canavas and viewer in the other screen.

Thanks...Does mac os have the ability to set it up like that automatically or do i need 3rd party software?

mac os x allows for screen spanning on video cards that can support it. you will not need any 3rd party software.

sooo, what is a more effecient setup for Final Cut and Motion work?

I prefer the 23 inch that I have now, but in a couple years, I want to buy another one.

anyone else?

no one?
