Menu Option Color Temp. Advanced Advanced Description There are several preset color temperature settings (9500K, 8500K, 7500K, 6500K, 5500K) available. The available settings may vary according to the personal preferences. To set a custom color temperature, you can further adjust the following items: Red Gain/Green Gain/Blue Gain Adjusts the Contrast levels of Red, Green, and Blue. Red Offset/Green Offset/Blue Offset Adjusts the Brightness levels of Red, Green, and Blue. Color A lower setting produces less saturated colors. If the setting is too high, colors will be overpowering and may appear unrealistic. Sharpness A higher value will sharpen the image, while a lower value will soften the image. Gamma Gamma refers to the brightness level of the projector's grayscale levels. Brilliantcolor This feature utilizes a new color-processing algorithm and system level enhancements to enable higher brightness while providing truer, more vibrant colors in the projected picture. It enables a greater than 50% brightness increase in mid-tone images, which are common in video and natural scenes, so the projector reproduces images in realistic and true colors. If you prefer images with that quality, select a level that suits your need. Noise Reduction This function reduces electrical image noise caused by different media players. The higher the setting, the less the noise. (Not available when input signal is HDMI.) Color Management Only in permanent installations with controlled lighting levels such as boardrooms, lecture theaters, or home theaters, should color management be considered. Color management provides fine color control adjustment to allow for more accurate color reproduction. Select Primary Color first and adjust its range/values in Hue, Saturation and Gain. 47
