Advance Mame and Menu with Eygo 19" in DOS

[Brent Strache]

Hello all,  I am so close to finishing up my cabinet, however I am having some issues with my video settings.  I get that vertical line on my eygo monitor on the left side when swiching to games.   I can move it out of the way with the monitor's controls, however then the screen is not aligned for other games and Advance Menu.  I believe it is happening when Advance Mame switches video modes.  I believe I need 640 x 480 all the time with some sort of streching.   I have gone over all of the .txt files and could not find anything to help me out.  The answer is probably there, I am just having problem understanding it.  I have my monitor specifications and I will list the below.  Can someone please help me out?  I am so close.  I can already tell this project was well worth the time and can't wait.  Thank you all in advance.

They are Eygo 19" arcade monitors.
