Introduction (Decision Hook)
Not all projection screens are built for the same environment.
Choosing the wrong type can completely destroy your image quality—even with a high-end projector.
The three most common options are:
- White screens
- ALR (Ambient Light Rejecting)
- CLR (Ceiling Light Rejecting)
Each serves a specific use case.
1. White Screens (The Standard Baseline)
Best for:
- Fully dark rooms
- Dedicated home cinemas
- Budget-friendly setups
Advantages:
- Natural color reproduction
- Wide viewing angles
- Cost-efficient
Limitations:
- Performs poorly in ambient light
- Washed-out image in bright rooms
Positioning:
Ideal for purists with controlled lighting environments.
2. ALR Screens (Ambient Light Rejecting)
Best for:
- Living rooms
- Moderate ambient light
- Mixed day/night usage
Advantages:
- Reduces side light interference
- Improves contrast in brighter spaces
- More flexible placement
Limitations:
- Higher cost
- Slightly reduced viewing angle
Positioning:
The most balanced solution for real-world environments.
3. CLR Screens (Ceiling Light Rejecting – UST Optimized)
Best for:
- Ultra Short Throw (UST) projectors
- Bright rooms with overhead lighting
Advantages:
- Blocks light from above
- Maximizes contrast with UST projectors
- Delivers TV-like performance
Limitations:
- Highly directional (limited angles)
- Not suitable for standard projectors
Positioning:
The premium solution for modern living room setups.

Common Mistake (Critical Insight)
Many users buy a projector first and choose the screen later.
👉 This is backwards.
The room conditions should define the screen type first, then the projector.
Strategic Recommendation
- Dark cinema room → White screen
- Living room, some light → ALR
- Bright room + UST projector → CLR
