Blend-in design The VPL-CH355 has a low-profile chassis, so it appears to blend into the ceiling or wall on which it is mounted. Advanced energy-saving features Advanced lamp technology enables robust energy-saving features. For example, greater brightness control in Auto Light Dimming mode saves considerable energy when the projector is left on without being used. During projection, Auto Picture Mode automatically adjusts light output to suit the projected scene. When you need to mute the picture temporarily, light output can be completely deactivated to minimise energy consumption.
