GCE vs LCE, What’s the difference?

Dynamic Tone Mapping

Dynamic Black

Dynamic Tone Mapping analyzes each frame of HDR content in real time, dynamically adjusting tone curves to preserve both bright highlights and deep shadow detail for a truer home theater picture. (Note: The STM image illustrates how a projector using a tone mapping setting that favors dark scenes may end up sacrificing bright details.)

How does DTM preserve the director’s vision?
Dynamic Black adjusts the projection light output based on scene content, ensuring optimal contrast for lifelike images.

Projection Distance

With 1.3x zoom, the W4100i offers flexible throw distances for big-screen home theater entertainment, no complicated installation required.

FAQ

What's the difference between LED and lamp projectors?

LED projectors feature instant power-on, quieter operation, and 6 to 10 times longer lifespans (20,000+ hours) with consistent picture quality and color accuracy throughout their life. In contrast, traditional lamp projectors carry lower initial purchase costs but require frequent bulb replacements, undergo color drift as the lamp ages, and demand warm-up time. Learn More
