You can also make keystone adjustments using the projector’s Setting 
menu. See page 58.

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.

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 to automatically 

reset 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. 

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.
