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.
