Hey guys, I've my mame pc with crt emudrivers and groovymame working for the most part I think when hooked up to my pc LCD monitor. I have the resolution at 640*480.
I transferred the pc to my arcade monitor via Jpac tonight at 31khz.
The lowest resolution I can select is 664*496.
Anything lower including 640*480 doesn't appear as an available resolution.
Any advice on where I'm going wrong? Thanks
