IRE and Film Mode settings on Benq projectors

Film Mode
Enhances picture quality when projecting composite image from a filmsourced DVD or Blu-ray Disc. Setting Off disables the function.

It's set on ON and greyed out. Source is HDMI.

What is this option?


On Benq projectors (not sure if all of them) there is an IRE setting.
From the manual:
Black Level
Sets the picture grayscale to 0 IRE or 7.5 IRE.
The grayscale video signal is measured in IRE units. In some areas which use NTSC TV standard, the grayscale is measured from 7.5 IRE (black) to 100 IRE (white); however, in other areas where PAL equipment or Japanese NTSC standards are used, the grayscale is measured from 0 IRE (black) to 100 IRE (white). We suggest you to check if the input source is with 0 IRE or with 7.5 IRE, and then make your selection accordingly.


My unit is a W2000 and the IRE is set to 0 and greyed out. This would make sense since it's sold in a PAL region.

Does this mean that when using a NTSC source there will be elevated blacks, like a mismatched color space? Using samples from here http://www.gvgdevelopers.com/concret...k2/test_clips/ I compared a 25fps PAL to a 29.970 NTSC. There was no visible difference in blacks and the color shades looked the same on MPC and VLC:
