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.
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 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.
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.

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. See
page 56 for details.
