Hello. I am trying to output 31khz video from a DDR Supernova arcade machine to an HDTV, using the OSSC. It uses a modified Playstation 2 for the main computer, connected to a board which provides VGA out and alternatively a 5 wire RGB/Sync/Ground connector which I could use, possibly through SCART or by wiring to a DSub connector, but I believe the signal would be the same. I am using the VGA connector. In 15khz mode it displays fine but 31khz mode says No Sync. Could anyone recommend a way to test the 5 wire connector, or if there is some setting I may have missed which might allow the VGA signal to be recognized? Thank you.
