3300 ANSI Lumens for Bright Gaming

With 3300 ANSI lumens brightness, the X3100i is designed to deliver a bright and engaging image across large screen sizes.

The high brightness output helps maintain image visibility in environments where some ambient light is present while supporting HDR highlights and detailed gaming visuals.

This makes the X3100i suitable for both dedicated gaming rooms and flexible entertainment spaces.

4LED Light Source for Long-Term Performance

The X3100i uses a 4LED light source designed to provide high brightness and long-lasting operation.

The supplied specifications indicate:

• 20,000 hours – Normal mode
• 30,000 hours – Eco mode

The 4LED system also contributes to the projector’s wide colour reproduction and consistent image performance.

600,000:1 Contrast Ratio

The X3100i provides a 600,000:1 FOFO contrast ratio with light-source dimming.

High contrast helps improve the distinction between dark and bright elements, which is particularly valuable in games featuring night scenes, underground environments, shadows and cinematic lighting.

Combined with HDR support, the contrast performance helps create greater visual depth.

HDR Gaming for More Detailed Worlds

The X3100i supports HDR10, allowing compatible games and video content to benefit from expanded dynamic range.

HDR can enhance bright highlights while retaining more detail in darker areas of the image.

The projector includes dedicated HDR gaming modes such as:

This allows gamers to optimize the visual presentation according to different types of content and gameplay.

The wide colour gamut helps reproduce vibrant game environments, detailed landscapes, character designs and cinematic scenes with rich colour depth.

Tailored Gaming Modes for Different Genres

This reduces the need to manually configure the projector whenever you switch between different consoles.

Ultra-Low 4.2ms Input Lag at 240Hz

Competitive gamers can take advantage of extremely low input latency.
