White vs. Grey/ALR Screens: Choosing the Right Color for Your Room

Introduction

• Many beginners assume a white screen is always the best choice. While true in some cases, the "color" of your screen can actually save your image from being washed out by light.
• This guide explains how to choose between White and Grey/ALR screens based on your room's lighting.

1. The Classic White Screen

• Characteristics: Reflects most of the light hitting it, resulting in a bright, vibrant image.
• Pros: Natural color reproduction; works perfectly in dark rooms.
• Cons: In bright rooms, "black" levels look grey because the screen reflects ambient light.
• Best For: Dedicated cinema rooms or bedrooms with total blackout curtains.

2. Grey and ALR (Ambient Light Rejecting) Screens

• Characteristics: These screens use specialized materials to absorb light coming from the sides/top while reflecting only the projector's light.
• Pros: Dramatically improves contrast in rooms with windows or overhead lights. "Blacks" look deeper and richer.
• Cons: The image is slightly dimmer than on a white screen; requires a brighter projector to compensate.
• Best For: Living rooms, open-concept spaces, or any room where you can't achieve total darkness.

3. Comparison Summary

Feature	White Screen	Grey / ALR Screen
Brightness	High	Moderate
Contrast (in light)	Low (Washed out)	High (Deep blacks)
Color Accuracy	Natural	Slightly shifted (but better contrast)
Ideal Environment	Dark Room / Basement	Living Room / Bright Space

4. Decision Guide: Which one should you buy?

• Choose White if: You can make your room pitch black and you want the most natural colors possible.
• Choose Grey/ALR if: You plan to watch movies during the day or in a room with ambient lighting.

Conclusion: Don't Let Light Ruin Your Investment

• A $2,000 projector on a white screen in a bright room will look worse than a $500 projector on an ALR screen. Match your screen to your light.
