Can some one help me configure my tablet?

I recently bought a Genius G Pen F610 tablet for my computer, as well as a 28’’ monitor. The problem now is that this tablet tries to fit the entire screen onto the small physical space. I want to know if there’s any way to make it so that I can have the tablet act as a mouse pad instead of a physical screen. Right now it’s trying to squeeze everything in and is basically useless.
