There is a simple reason why the picture is so dark: the white level is set to low and there is no ioctl to change that. You can change the white level in the matroxfb_maven.c source by changing the register 0x1E from 0x89 to for instance 0xD0. In my case this gave a nice bright picture (on G200 and G400). I'm currently about to create a patch which will add an ioctl to set up the picture parameters for TV-out. This will also allow to change the deflicker mode. Mike
