Addendum on 29/06/14:
Due to questions from other readers:
We have the projector now used during the World Cup for watching football, source ARD HD and ZDF HD, blurring or tightening of the image at fast pans none of us could find.
To assemble:
The projector has no lens shift, so I can not shift the picture horizontally or vertically. For this reason, an absolutely precise orientation is mandatory for ceiling mounting !!
First read the list on page 15 of the manual, specify distance from the projector to the screen based on the screen size, then create angle laser on the center of the screen and measure the right angle direction mounting location, at the intersection of distance and angle, the lens must not ( the holder) are.
Now even the suspension height: measure upper edge of image area to ceiling, then on page 15 to take back to the table the value of "E" from the last column (at me with 4m distance are the ca.85mm.
Deduct this from the precisely measured distance to cover, for example 20cm OK image to ceiling-8.5cm (value E) = 11.5 cm. This is the distance between the middle lens and ceiling, which you have not half the height of the projector housing deduct, so about 5cm.
This results in my example a ceiling mount with a height of 6.5 cm, for example this one:; qid = 1404022136 & sr = 8-5 & keywords = ceiling mount projector +
Sounds complicated ?? Isses but just so I get an absolutely undistorted image back. Once I use the digital keystone correction, the picture is worse.
