In theory setup 7.5 for USA NTSC analogue. I do not know what it should be in theory for digital HDMI or HighDefinition sources as the setting is a relic of analogue.
In practice if you calibrate brightness after selecting any of the setup options 0, 3.75 or 7.5 it will have the correct black level, you just lose the ability to easily switch black level between USA NTSC 7.5 and PAL or Japanese NTSC 0ff.
As I mentioned in the previous post, it appears to have an effect on the bottom end of the gamma curve, how apparant shadow detail is. In theory it should not, in practice it does. How obvious you want shadow detail to be depends on viewing environment, as light colored walls and ceiling will bounce light from the screen back onto it washing out the shadow detail. But if it comes out of black too rapidly, shadow detail maybe very obvious, but perceived contrast of bright scenes maybe less.
I own a Mitsubishi XD460U projector, similar software to the HD1000U. I personally use 3.75 then calibrate brightness, despite living in the UK where I should be using PAL Off. My viewing room is a batcave with a white screen.
