What projector are your using?

How wide is your image?

How far back is your projector?

How tall is the top of your image from the FLOOR?

How far is the bottom of the projector from the FLOOR?

Are you using you are using any lens shift or keystone.


Reason I am asking is that I thought all projectors when flipped upside down, had the center of the lens aligned with the top of the image. But when I flipped my Sony 400Q upside down the top of the image is 12" lower. I am now looking for a new projector which will work in my HT :)

Robert,


1. Z9000U

2. 90" diagonal.. but I zoom down a little to fit a Greyhawk 64" diagonal. That makes the image about 72" wide.

3. Throw is 10 feet (lens to screen)

4. 8 feet 3 inches from bottom of proj. to floor

5. 7 feet 3 inches from floor to top of screen

6. I am using -21 keystone and about 98% of the available down lens shift.


It should be noted that the projector is right side up (not inverted). Its setting on a soffett above the viewers head.


I would not change a thing in the setup of the room. The projector is not obvious and new viewers are always curious as to where the picture is comming from! Plus the soffett help mute the already quite Z9000U fan and color wheel.

As a rule of thumb I have found that the bottom of the projected image will be aligned with the center of the projector lens. This may vary slightly with projectors. My setup:


Sharp DW100U - ceiling mount.

100" diagonal 4:3 Firehawk Electrimask (H)

Roughly 7' to bottom of projector (low ceilings)

Roughly 14" to bottom of projected image.


Not using any keystone correction as this is an LCD unit.


Good luck!
