not sure what you mean but:
arcadeVGA output's 15khz + 15khz standard standard arcade monitor = nice native display at 15khz if you have a med. res 25khz a trident blade pc card maybe the better for the 25khz med. res. type. the arcadeVGA kinda support's the 25khz but not as good as the 15khz that they were origanaly made for.
