I'm afraid that you need to be more specific about what you want. We don't know if you have one monitor or two, if you want to have your desktop span both monitors or have two different pages on one monitor. I have no idea what "two different pages on one monitor" is, but that's what your question sounds like.
More detail please, and we will be happy to help. My first guess is "try Display Settings." Right-click on an empty piece of desktop, select Properties from the menu that pops up, go to the Settings tabs. and play.
