Tips & Recommendations
Room Preparation
For best results with your 100" projection, use blackout curtains and paint the wall matte white or use a proper screen. Dark walls absorb stray light.
Projector Placement
Standard throw projectors need 12.5-16.7 feet from the screen. Consider a short-throw projector if space is limited.
Screen Selection
A 100" retractable screen offers flexibility for multi-purpose rooms. Ensure it's tensioned to prevent waves in the image.
Audio Setup
A 100" cinematic screen deserves quality audio. Consider a soundbar at minimum, or a 5.1 surround system for true home theater immersion.
