ok thanks for the reply.

haha "brightness", yes "br" would avoid confusion indeed :)

I give up on my LUT problem, I'll just switch LUT's when I switch 
displays.....a little trade off for a fantastic picture quality I'd say ;)

well you know the s2 is not very sensitive in dark areas, even in "qh" 
mode...and I'm projecting on a 2 meters large screen.

here's what it gave with the window borders in a pitch black room :

and same room/same projector, only with the overscan set to 92% to take away 
the window borders :
