 +Note:- According to the [[schematics:​console_related_schematics#​dreamcast|schematics]] the HSYNC and VSYNC signals come directly from the '​HOLLY'​ GPU and are sent to both the DAC/Encoder and the AV port, which means they are likely active in all modes (Even standard '​TV'​ mode, when no RGB signals are present) However CSYNC is generated by the DAC/​Encoder,​ so is unfortunately only active in specific modes.
