Menu Image Settings Description Wall Color Designed to adjust the colors of the projected image when projecting on to a wall without a screen. NOTE: A screen is recommended for more accurate color reproduction. Brightness The higher the value, the brighter the image. Lower values will result in a darker image. Contrast Use this to set the peak white level after you have previously adjusted the Brightness setting to suit your selected input and viewing environment. Sharpness A high value results in a sharper picture; a low value softens the picture. Color Adjust an image from black and white to fully saturated color. Tint The higher the value, the more greenish the picture becomes. The lower the value, the more reddish the picture becomes. Gamma Reflects the relationship between input source and picture brightness. 49
