Best driver for Compaq 420K monitor.

I am using a Compaq 420K monitor on my Pentium 166 PC with Windows98 SE. Problem is that I had to choose the driver for Compaq 800x600 monitors, and I get a 1" black boarder around the screen. There are no controls that I can see on the monitor to change the screen size. Is there a better driver for this monitor than the one I am using now? It's FCC ID # is GQBCDS-460X.

Thank you,

Paul
