On a Christie, they call it "Presentation" but it is the same as Barco's "Resizing". Christie used TI's naming, in fact.
So, in order to do what you desire (lower the entire image), you need to lower both "corners". It isn't as graphical as Barco's but it is the exact same thing (they are controlling the exact same TI boards). In fact, you can use a Barco PCF/Screen in a Christie (or NEC) and vice-versa. Christie or NEC even have a predefined scope screen file where the shift is already in there (I'm 99% certain that screen files are swappable between series 1 and series 2). So, if you are inclined to do this sort of thing (shift the image down on the imager rather than lens shift, and there is good reason to do so since a lens that doesn't move tends to stay in position better than one that does move), then it would be advisable to have a screen file with you that already has the resize/position as well as the scope masking already at the full scope dimensions so all you have to do is drop it in, tweak the masking portion and give it a new name.
Note too, the PCF or input file HAS to be for 2048x858 so the imager knows that it can do this shift. Also note, if the projector is off center laterally, you can center the image on scope laterally and tweak the FLAT image laterally also using the Resize/Presentation controls.
