The Da-Lite ambient light rejecting (ALR) screen line gets an addition-- Parallax 2.3, a screen the company says has a very gradual brightness drop-off, ensuring image quality is maintained even when viewed from the side.
Designed for both pro AV and home theatre applications, the Parallax 2.3 consists of multiple micro-layers to achieve 96% ambient light blocking properties, together with a viewing cone of 46-degrees. The result is a bright, colourful image without glare, regardless of how much light is in the room.
