Is it possible to adjust for keystone in two directions.

As an example say I put the projector close to the corner of a room and near the floor but still wanted to project near the center of the wall on the opposite side of the room.

Would this create too much distortion or loss of focus?

Yes, it's possible to do that as long as the PJ's not off-axis by too much in either direction though.

[PorQue?]

Do the same equations apply or are they a little different because of the added dimension?

I assume that the max correction would still be about 15 degrees.

[Shrivel]

I would imagine the max angles would actually be less if correcting over 2 dimensions, if my geometry is correct ;-)

Take a look at my thread and read what V&J said.

Its a pretty good idea
