Projecting39 You can also make keystone adjustments using the projector’s Setting menu. See page 58. Adjusting the Brightness The brightness of an image depends on the source you are projecting and the amount of light in the room. If the image is too bright or not bright enough, here are two ways you can adjust it: ■Change the Brightness setting in the Image menu. See page 54. ■Select Low or High for the Brightness Control option in the Setting menu. (See page 58.) Low brightness mode extends the life of the lamp and decreases the fan noise.

(You must be projecting an image for this button to have any effect.) The screen turns black for a few seconds, and then the image appears again. After the image reappears, it takes about three seconds for the correction to take effect. Don’t press any other buttons while this is happening. Adjusting the Color Mode You may want to adjust the color mode to select a setting that is appropriate for the image you’re projecting and the environment in which you’re projecting it. If you’re projecting computer or RGB video images, the default color mode is Presentation, which is appropriate for presentations in bright rooms. For other images, the default color mode is Dynamic, which optimizes video images using natural colors. Color Mode button Auto button note If the Auto Setup option in the Signal menu is enabled, the projector automatically corrects computer images. Normally you don’t have to press the Auto button.
