and check the table below for the cause of the problem.

FRONT/REAR
This setting should be changed in
accordance with the projector

Set to “FRONT” when using a
normal reflective screen with the
projector positioned in front of the
screen, and set to “REAR” when
using a translucent screen with the
projector positioned behind the
screen.

LAMP POWER
This setting changes the lamp
brightness. When set to “LOW”, the

picture luminance is not essential or
for watching movies.
