4. Installing projection screen
.
4.1. Positioning projection screen
• Determine where you would like to mount the screen beforehand. You may do
this with the aid of the information on the product specific information
sheet.Think carefully about the necessary space and the location of any electrical
connections.
• The projector lens should preferably be positioned at a right angle to the vertical
line between the top and bottom of the screen.
• The aspect ratio of the screen should correspond to the aspect ratio of the
projector.
• Make sure that the projected image will fill the whole screen. This has to do with
the zoom factor of the projector.
• There should not be any obstacles between the audience and the screen.
• Make sure that the audience is seated within the range of the ideal viewing angle
for the screen. The ideal viewing angle is dependent upon the type of screen
fabric. For further information, see www.projectascreens.com.
• For use in a living room (Home Cinema), maintain a height of 60 to 90 cm
between the floor and the bottom of the unrolled projection screen. This will
allow the audience to always see the full screen. For business use, a height of
approximately 125 cm is suggested.
• Ambient light has a substantial effect on the image quality. For this reason, make
sure that there is no lighting equipment standing or hanging too close to the
screen and that no direct light falls on the screen. For an ideal projection quality,
it is best to darken the room.
4.2. Wall or ceiling mounting
• For mounting on wall or ceiling, it is best to use the mounting materials supplied
with the screen.
• These materials have been tested and approved for the mounting of the
projection screen to concrete or brick constructions.
Important! You are responsible for finding out (on your own or with the aid of a
structural engineer) whether modified mounting materials are necessary. For
example, if you would like to mount the screen to a wall system made from
plasterboard.
• For the installation of an electrical screen, determine the location for the wall
switch. Install out of the reach of children and at a minimum height of 1.5 meters
from the floor.
• Do not install the switch in the area where the projection screen is to be
unrolled. During the operation of the screen, the moving parts should be within
your field of vision so that you can check to see if anyone is standing within range
of these moving parts.
• Special ceiling brackets are available as accessories for mounting the projection
screen to a false ceiling. See also section 9 ‘Accessories’ or ask your supplier.
• A special wall bracket is available as an accessory for mounting the projection
screen at a certain distance from the wall (for example, if there is an obstacle in
the way). See also section 9 ‘Accessories’ or ask your supplier.
