After I posted the tv presets I thought about them again. The theater setting of 90 and 90 does give a reasonable impression [considering the two little built in speakers] of the big audio I hear at a movie theater. I don't get HBO but I can sometimes see the pic and hear the audio somewhat. The signal to noise is way worse than 12db though. It is perfect for playing with the bass and treble controls for max intelligibility. I end up around 60 and 70 every time. Strictly high boost does not work for me.
