Adjusting the Image Shape

The projector automatically corrects images that are distorted when the projector is tilted up or down (up to a 15° tilt). The Keystone window appears on the screen while the projector makes the correction. If the projected image still isn’t rectangular or has a “keystone” shape, do one or more of the following:

❏ If your image looks like

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.

The following table lists the available color modes.

You can also make keystone adjustments using the projector’s Setting menu.

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, do one of the following:

❏Change the Brightness setting in the Image menu.

❏Select Low or High for the Brightness Control option in the Setting menu. Low brightness mode extends the life of the lamp and decreases the fan noise.

To change the color mode, press the Color Mode button on the remote control until you see the mode you want. The currently selected setting appears in the upper right corner of the screen. You can also use the projector menu system to select the Color Mode in the Image menu.

Correcting Computer Images

If you’ve connected a computer and the image doesn’t look right, or it doesn’t fit properly on the screen, press the Auto button on the remote control or the Enter button on the projector. This automatically resets the projector’s tracking, sync, resolution, and position settings. (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.

Note:

If the Auto Setup option in the Signal menu is set to OFF, the Auto function will not work.
