SCREEN REQUIREMENTS
Fitting the image to the screen
It is important that your screen is of sufficient height and 
width to display images at all the aspect ratios you are 
planning to use.
Use the conversion chart to check that you are able 
to display the full image on your screen. If you have 
insufficient height or width, you will have to reduce the 
overall image size in order to display the full image on 
your screen.
14:3 = 1.33:1
W = H x 1.33, H = W x 0.75
216:10 = 1.6:1...

SCREEN REQUIREMENTS
Positioning the screen and projector
For optimum viewing, the screen should be a flat surface 
perpendicular to the floor. The bottom of the screen should be 1.2 m 
(4 ft) above the floor and the front row of the audience should not 
have to look up more than 30° to see the top of the screen.
The distance between the front row of the audience and the screen 
should be at least twice the screen height and the distance between 
the back row and the screen should...

POSITIONING THE IMAGE
Positioning The Image
The normal position for the projector is at the centre of the screen. Ho\
wever, you can set the projector above or below the centre, or to one side, 
and adjust the image using the Lens shift feature (known as rising and falling front) to maintain a geometrically correct image.
Notes
 For more information on shifting 
the lens, see Lens menu in the 
Operating Guide .
 Whenever possible, position the

POSITIONING THE IMAGE
Any single adjustment outside the ranges specified on the following page may result in an unacceptable level of distortion, particularly at the 
corners of the image, due to the image passing through the periphery of \
the lens optics.
If the lens is to be shifted in two directions combined, the maximum ran\
ge without distortion will be somewhat less, as can be seen in the 
illustrations below.
Notes
 For more information on shifting 
the lens, see Lens menu...

Maximum offset range
The maximum offset range available with no distortion or vignetting is dependent on wh\
ich lens is used. Shifting the lens beyond its 
undistorted limits may be physically possible, however you may experienc\
e some vignetting or distortion.
