I guess I just don't understand what you're trying to do.
Here's my understanding of what's going on.
A 2.4:1 widescreen movie does not occupy the upper and lower scanlines of a BD or DVD image. It uses only the central 800 scanlines of a 16:9 (~1.8:1) 1920x1080 BD video image. I.e. it's letterboxed. The upper and lower 140 scanlines have to be projected above and below the wide aspect ratio (2.4:1) screen onto a black, non-reflective surround.
As I read the manual, the "shutter" adjustments substitute the projector's "black" value for whatever video signal is in those upper and lower scanlines, often producing a darker image in that area than is provided by the video signal coming from the video disc.
In order to fit all 1080 scanlines on the screen, so you can see the entire PC desktop image, you have to reduce the vertical size of the projector's native 16:9 1920x1080 pixel image. In other words, you have to change the (zoom) magnification of the image being projected on the screen so that all 1080 scanlines fit in a smaller vertical dimension, bringing the upper and lower 140 scanlines into view.
What am I missing?
