You can use the Setting menu and the Advanced menu to adjust a 
variety of projector functions.

*

You can also use the Keystone button on the projector to adjust this setting. If the image is noticeably uneven, 
reduce the Sharpness setting on the Video menu.

Keystone

Corrects a trapezoid-shaped, distorted image to a 4:3 ratio rectangle, adjusting up to a 
±15

° tilt. Press the right or left side of the Enter button to adjust the setting and see 

the results.*

No-Signal/Msg

Specifies whether no screen, a black screen, or a blue screen is projected when no 
video signals are received.

Prompt

Controls whether the projector displays a temporary message indicating the current 
input source (Computer or Video).

A/V Mute

Controls whether the projector displays a blue or black screen when the A/VMute 
button is pressed.

Sleep Mode

Enables or disables sleep mode, which turns off your projector’s lamp when it hasn’t 
received any image signals for 30 minutes. Press the 

Power button on the projector 

or the remote control to resume projection. 

Reset

Returns the Setting menu options to their factory defaults.

Language

Selects the language the projector uses in the menus: English, French, German, 
Italian, Spanish, Portuguese, Japanese, Chinese, or Korean.

Color Setting

Selects the color temperature and RGB (red, green, blue) settings of the image. 
Increasing the color temperature creates cooler whites and decreasing it creates 
warmer whites. Increasing the RGB intensity strengthens the colors and decreasing it 
weakens the colors.

Rear Proj.

Mirrors the projected image on its left-right axis so it appears correctly when you’re 
projecting from behind onto a transparent screen. 

Ceiling

Flips the projected image on its top-bottom axis so it appears correctly when you 
mount the projector upside-down from the ceiling. 

Reset

Returns the Advanced menu settings to their factory defaults.
