Sony VPL-X2000U Mode D'emploi page 7

• Flexible setup
The lens shift function allows you to install the projector in a wide range
of locations, without worrying about keystone distortion (the picture going
out of square). The power focus and power zoom functions also let you
change the size of the projection screen without having to move the
projector.
• Stack installation
Thanks to the lens shift function, up to three projectors can be stacked,
which improves the brightness of the image.
• Fail safe function
The projector uses four lamps for light source. Even if one of them has
burnt out, you can still use the projector. If two lamps have burnt out, the
projector will automatically enter into standby mode.
