Arcade monitor controls??

[Hellfire666]

Okay, I am a complete newbie and I know I should not have done this....however, when trying to get mame w/arcadeos to work....I messed around with all the controls on the back of the monitor...I just CANNOT get the arcadeos front end to stay still and in the middle of the screen on my monitor.....can anyone help me?  I have messed with the controls for about 3 hours no and I can get it somewhat okay, but it still moves around on its own and the lines arn't always straight etc.....Is there software to fix it or set the monitor?  Or anything?

If I recall arcadeos has built in controls that you can manually adjust to position it on the screen--press 2 to bring up the menu and have a look through that.  I would center it as best you can outside of arcadeos (with monitor controls) so that you know where its supposed to be, and then go into arcadeos and do the adjustments there (and not the back of the monitor).
