With a ceiling mount pj and a shallow angle down to the wall, is there a keystone issue that I will need to deal with? I'll be mounting the pj about 22" higher than the center of the floor to ceiling measurement and projecting out about 100" (using the throw calculator in the tools area of the forum).

Also, my plan was component video out, into a good quality component selector box, and then out of the selector box to a component to vga cable from ramelectronics. Will this work?

Thanks in advance for the help.

It would be helpful to know the angular degrees of keystone correction you hope to use. We can do 10º simply and without problems.

I've calculated a 7 degree angle of decline from the ceiling mount, well within the 10 degrees.

PJ lens to screen is 155"
screen area is 8' x 6' in 4:3 and 8' x 4.5' in 16:9
Level mounted ceiling PJ would project the center of the image 13" from the ceiling
Center of the image on the screen should be 27", which means it needs to drop 14"
Using a right triangle calculator and inputing the sides 155" and 14", I came up with a 6.97 degree angle

this will all need to be re-worked when the box, light and lens are put together, but it seems well within the 10 degree limit you spoke of, so I'm moving ahead knowing the keystone issue should be solved with an adjustment on the lens side fresnel.

Sound ok?
