The connector is described in the Hardware Manual as "LVDS CONT connector" in the LVDS chaper, but it is not clear to me what exactly is supposed to be connected to it, and how standard it is. Laurent: do you know more? Note that Ebisu has the same connector, but the signals are shared with SW4, making them mutually exclusive. The Ebisu Hardware Manual does mention the connector, but not in the Display Output (LVDS) chapter. Gr{oetje,eeting}s, Geert
