I just got a die hard arcade cabinet and a jpac, I hooked it all up and can see my windows screen but its flying all over the place.
I am using soft15hz, which I assume is working because jpac prevents bootup unless its a safe signal.
On the back of the monitor there is a FOCUS and a SCREEN dial, one focuses and the screen dial seems to adjust brightness, Is there a control somewhere to track the picture possibly? Like an old vcr ?
