It's the same color depth if you are using xrandr. It's likely a problem with the gamma settings for the crtc driving DVI-1 or the dither setup is wrong for the tmds transmitter used for DVI-1. Does playing with the gamma via xgamma or xrandr fix it? Alex _______________________________________________ xorg mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/xorg
