Resolution on 19 inch CTR Monitor

[uaw420rook]

I went a bought the 19incher from office max. I tried to change the resolution to 1600-1200. It didnt change the table size, but changed the windows area. The tables dont overlap, but i have to move my curser across the screen to view each table fully and lose parts of the other tables. Is this the way it is supposed to work. It is uncomfortable playing this way for me. I tried searching on this subject, but I suck at searches because of my spelling. thanks
