Using both horizontal and vertical shift is the worst thing to do. However, those that do it will scream I do it and its fine. It all depends on the viewer and frankly if you are watching something and get into that rather than into how the projector is doing with it, loss of image edge focus and increased chromatic abberations are not really that troublesome.
Me. I would add a lateral shift bracket to my mount and just avoid using lateral lens shift since its so easy and inexpensive to do.

Thanks for the reply. The mount I have is a "Sanus Universal Projector Mount". Nothing special to be sure, but did the job. The problem being I placed it so the lens would be centered on a Sanyo PLV-Z5 projector....
I'm not sure is I could find a "lateral shift bracket accessory" that would work with my mount - but if the picture is reduced to the point where I can notice it from a seated position (and maybe even if I can't now that I know it's likely not ideal) I'll have to look into my options I guess.
Thanks again - lurked here for years and have only now had a question where I didn't see asked already.

I've been trying to buy one used but mist out on his and another one that was posted in the avs for sale section just days ago.
