When the input signal doesn't fill the plasma, we seem to have two options for the bar fill - "auto" and "fixed intensity". Auto gives us a peculiar "grey picture fill", whereby the areas are filled with what the monochrome equivalent would be had the picture been stretched into those areas - which is most disturbing and, frankly, naff. The fixed intensity seems to be fixed as a very light grey. Putting this against the piano black frame looks atrocious. We assumed that it would default to black to match the plasma surround. Or that we could fix the fixed level - and fix it to black, as all the other letterbox/side bars we've seen are. The grey bars completely destroy night-scenes, especially viewed in a darkened room. PLEASE - can anyone tell us how to get these black?
