[directfb-users] Re: Matrox G450 TV Out - Black and white picture?

Hello J-F,

I have a Matrox G450 on a kernel 2.4.21. I have installed DirectFB
according to Ville Syrjälä's Howto and I got mplayer working (with the
nospic option) but I get only black and white output.
Same result with the alternative "/dev/fb" method.

Any idea where that could come from?
Check your cable and settings carefully.

Most likely you're outputting a s-video signal, where y/c (y == luminance, ie. black/white informations, c = chrominance, ie. color informations) are transmitted on two different wires, but your tv expects a composite signal (ie. where color and lumincance informations are mixed together).

If you input the lumincance only to the composite input, you'll get a black/white picture.

So either your cable is broken or tell your tv to use s-video for the input you've connected your card to, or use the composite plug of your cable.

Thanks in advance!
If that does not help, exactly tell what settings you've chosen and what output from the card you plugged into which input of your tv.
