Projectors with massive lens shift ranges

There is various software and hardware you can get to warp images. Something like this

I would have to ask why there is such a limit of the positioning?

There is a alternaive solution to most things, if we can take a step back and look at the bigger issue and picture.

Generally projectors with lens shift are limited when either direction is used towards the limits. Therefore being able to shift 120% down, may limit the horizontal shift (even if it states a higher figure when used on it's own).

Having said that I don't think I know of a model that would give that range of shift. JVC, Sony and Epson models may give fairly flexible shift (I have a JVC X500 myself) but well short of your requirements. Another issue is that the more shift that is used then the image will tend to soften, especially so with horizontal shift.

I'd follow the advice on here and consider other options: Projector lifts for example, or using a coffee table instead of a ceiling mount, or if it really comes to a flat panel display (though it won't be a 'cinema room' in that case, just a loud TV ).

Could you mount the projector on an arm which sits it against the beam but swings across and down to a preset position when needed?

Just bear in mind that any lens shift by software alone is image manipulation, so the projection is still the the same weird rhombus shape, in dark scenes you may be aware of the actual shape of the projection versus the corrected version.

This effect is worsened with projectors with poor black levels.
