•
Since the projector features an ultra short throw, be aware that it is required to select a
screen carefully to have better performance.
- A soft screen such as a pull-down screen may cause serious distortion of a projected
image. A hard screen such as a board screen is recommended for use with this projector.
- A high-gain screen such as a bead screen that has narrow viewing angle is not suitable
for this projector. A low-gain screen (around 1.0) such as a matte screen that has wide
viewing angle is recommended for use with this projector.
-
A screen with a weave pattern may cause moire on the projected image, which is not a failure
of the projector. A screen that has less moire effects is recommended for use with this projector.
NOTE •
Installation position, picture mode, altitude, and operating environment
may affect the brightness of the display.
