display questions

[medic0011]

Ok, I've been meaning to start my MAME project for only about 5-6 years........

I've finally got the project rolling and have everything (I think) that I need.

The dedicated computer works with MAME 32, controls are all in from ultimarc and Happ.... I even have the cabinet 50% built....

Question is: when I start MAME 32 and run a game program, there is about 1" around the screen that is black and is not being taken advantage of.  I want to capitalize on every bit of screen size possible (22" comp monitor) but it is not stretching the game out to maximize that opportunity. 

I am using the standard settings that came with MAME and have not changed them...

Any suggestions?

Thanks in advance.
