Christie WX& LX Series

The WX series does seem to allow for significant horizontal and vertical offset, however you have to be careful in understanding their definition of offset as it is apparently not the same as shift. 75% offset does not mean that the projector could be offset by 75% of the image width but rather than it can be offset by 75% of the distance from the centerline to the edge of the image, or one half what might be assumed if viewed as a shift value. Thus for the 108"x81" image noted the projector could be 40.5" off to the side.
The online information for the LX505, LX700, LX1000 all show +/-50% vertical and 10% horizontal shift. In this case it apparently is shift and thus for the 108"x81" image the projector could be up to 10.8" horizontally off the image centerline. Not surprisingly, that also seems to be the exact same shift as the Sanyo you are dealing with allows.
I think Christie does need to verify the information they show for the LX605 and LX1500. The LX605 online specs state "Offsets: Horizontal - 50%*; Vertical - 10%*" and the brochure references that same 50% horizontal and 10% vertical offsets. However, Page 17 of the LX605 manual contradicts that information and instead defines a 50% vertical and 10% horizontal shift, which makes much more sense. Similarly, the online specs and brochure for the LX1500 indicate a "Horizontal and vertical offset up to 120% vertical and 78% horizontal (depending on lens)" while Page 18 of the LX1500 User Manual again disagrees and again indicates a 50% vertical and 10% horizontal shift.
This doesn't fix your problem but I think you'd have the same basic problem with many other projectors, although the Christie WX series projectors do seem to be able to allow more image shift for most of the available lenses.
