Get games to fill the PC monitor

[topdawgg]

I am currently using 1024x768 resolution in mamewah and in windows, the refresh rate is set to 75 on both.  The games all seem to run just fine, but I would like to know if there is a way to get the games to go a little further left and right... and maybe up and down.  I read through the FAQ here and understand that the old games dont normally run on this high of resolution... but I dont understand exactly what resolution has to do with the game orientation on the monitor.

Any help would be great.

Any help on changing the game width?

Need more information.

eg: What software and OS are you using?
