So, I got my Inspiron 9300 today

I will ask this here rather than in the Computer forum which seems to be haunted by more tumbleweeds than posters. I love my 9300, but I am technologically retarded.

I play Party and each table I bring up has one inch of black space along the right and bottom edge of the table. It is really starting to piss me off. How do I fix it?
