As I understand it, from reading the forums here, keystone correction is limited to 15 degrees. My question is about keystone correction in two directions. Am I limited to 15 degrees total correction or 15 degrees in each direction.

For example: Let's say I want the projector above and to the left of the screen. Can I use keystone correction to shift it down 10 degrees and to the left 15 degrees or am I stuck with 15 degrees total?

Also, When tilting the screen to correct for keystoning, is the tilt of the screen equal to the amount of keystoning. For example: If you tilt the screen five degrees upward is that equal to five degrees of keystone correction with the fresnel?


Thanks

15 degrees total.

Actaully slightly less, because horizontal keystone requires a bit more distance change between the one side of the screen and the other, and this makes up a signifigant portion of the limitations on keystone correction.
