I know these are poor monitors for actual use due to the latency, but I like the idea of having a small RGB screen for diagnostics. The issue I'm having is that while composite on inputs A and B work fine, S-Video on input A and RGBS on input C just give a "no sync" message. Not sure where to start looking at possible points of failure here. Also a fair chance I'm just missing something with the configuration (changing input A to be S-Video rather than composite and changing input B to be RGBS rather than component for example).
