Yes and no. More no, as I did not get a picture. As I wrote above I tried to build an adaptor cable and _not_ a connector cable. My adaptor cable has a _female_ scart connector for use with a normal scart cable with all pins connected. So schematics found on matrox side are for a connector cable with a male scart plug. Looking at the following picture: http://www.sm.go.dlr.de/~bob/scart/scart.gif I had to swap pin20 with pin19, and pin18 with pin17. On the other unused side 2,4 are swaped with 1,3 . When that was done, I got a picture and I recognized that I swaped blue and green components. By this I can tell now that RGB signalling line works, as both TV display modes (composite and rgb) showed wrong colors. That was with matrox-cable-type=scart-rgb. By specifying matrox-cable-type=scart-composite I could switch from composite (correct colors) to rgb (wrong colors). So now I have the right colors in both modes, I'm a bit disappointed by RGB mode. Colors are looking a bit flat compared to composite signal. > ftp://ftp.matrox.com/pub/mga/forum_img/scart.gif > ftp://ftp.matrox.com/pub/mga/forum_img/g400boc.gif > > Did you check the cable with a multimeter? > > Did you connect it to the connector marked '2'? > > Can you try it with another TV? > > All I can really say is that it works for me.
