Hey Guys,
I finally got GroovyMAME working after following Calamity's guides. Overall I think I've done everything right but I'm having some weird monitor problems whenever I run a game that outputs below 17khz. First off I get a very high pitch buzz that sounds from the monitor. Secondly the picture does not fill the screen properly, it is too far to the left and not centered vertically. Lastly after about 45secs the picture starts to distort and the right side starts creeping in. Here are two videos showing what is going on.

I do not have any of these issues if I don't run GroovyMame and just output at 600x480 at 60khz. I'm probably doing something stupid but any ideas on a fix would be appreciated.

That sound is awful. Do you have a PCB to test instead? Can you try with the arcade_15 preset instead of the d9400?

Yeah it is terrible. I do not own any PCBs so I'll have to continue with VGA and my computer. I am traveling this week but I will try the arcade_15 preset when I get back. Thanks for the help Calamity.

Alright. I tried the Arcade tri-sync option and things got better but there is still a high pitch sound below 18ish kHz. I did not get any of the weird distortion but I didn't play it very long due to the high pitch noise. Any ideas?
Do you think this is software or possibly hardware? I'm more than happy to continue to test whatever you think it may be.
