Yes, but I think ttkgeek may have meant as in go past that whilst all is still visible on one screen, or in a game. In this case it is not possible as the max resolution capability is 1024 x 768 with your screen because this is the amount of physical pixels that you have.... the only option is to get that higher resolution via a virtual desktop as the others mentioned, or to get a new LCD (the SXGA goes up to 1400 x 1050).
