Selecting an input source
The projector can be connected to multiple equipment at the same time. However, it only 
displays one full screen at a time. When starting up, the projector automatically searches for 
the available signals.
If you want the projector to always automatically search for the signals:
•Under the Advanced OSD menu, go to the System Setup : Basic menu, and enable 
Quick Auto Search (see Quick Auto Search on page 54).
•Under the Basic OSD menu, if there’s no signal connected to the projector, go to 
Auto Source Search and enable it; if there are signals connected, go to the Settings 
menu, and then enable Auto Source Search.
To select the video source:
1. Press   to display the source selection bar.
2. Press  /  until your desired signal is selected and press  .
Once detected, the selected source information displays on the screen for seconds. If 
there are multiple pieces of equipment connected to the projector, repeat steps 1 to 
2 to search for another signal.
The native display resolution of this projector is in a 16:9 aspect ratio. For best display picture 
results, you should select and use an input signal which outputs at this resolution. Any other 
resolutions will be scaled by the projector depending upon the Aspect Ratio setting, which may 
cause some image distortion or loss of picture clarity. See “Aspect Ratio” for details.

Adjusting the projected image
Adjusting the image height
The projector is equipped with 2 adjuster feet. These adjusters change the image height.
To adjust the projector:
• Screw the adjuster feet to adjust the 
image height.
• To retract the feet, screw the adjuster 
feet in reverse direction.
If the projector is not placed on a flat 
surface or the screen and the projector are 
not perpendicular to each other, the projected image becomes trapezoidal. To correct this 
situation, see Correcting keystone on page 35 for details.
• Do not look into the lens while the lamp is on. The strong light from the lamp may cause 
damage to your eyes.
• Be careful when you screw the adjuster foot as it is close to the exhaust vent where hot air 
comes from.

Picture Mode
Selects a preset picture mode to suit your operating 
environment and input signal picture type.
The preset picture modes are described as below:
• Bright: Maximizes the brightness of the projected image. 
This mode is suitable for environments where extra-high 
brightness is required, such as using the projector in well-
lit rooms.
• Graphic (sRGB): This mode is best for making a still-
image presentation when your presentation slides use 
mostly graphics and minimal text. A small amount of 
ambient light is required.
• Motion Video: This mode is best for playing a video clip 
in your presentation. A small amount of ambient light is 
required.
• Lectures: This mode is best for making a presentation 
when your presentation slides use mostly text and 
minimal graphics. A small amount of ambient light is 
required.
• Cinema (Film): With well-balanced color saturation and 
contrast with a low brightness level, this is most suitable 
for enjoying movies at home where there is a small 
amount of ambient light.
• Vivid Color: Maximizes the visual effects and displays 
images in bright and vivid colors.
• User: Recalls the customized settings. Access the 
Advanced OSD menu and see User Mode 
Management for details.

Aspect Ratio
The native display resolution of this projector is in a 16:9 aspect 
ratio. However, you may use this function to display projected 
picture in a different aspect ratio.
• Auto
Scales a picture proportionally to fit the projector’s native 
resolution in its horizontal or vertical width. This makes the 
most use of the screen and maintains the aspect ratio of a 
picture.
• 4:3
Scales a picture so that it is displayed in the center of the screen 
with a 4:3 aspect ratio.
• 16:9
Scales a picture so that it is displayed in the center of the screen 
with a 16:9 aspect ratio.
• Wide
Stretches a picture in a horizontal direction to fit the screen 
width. It does not alter the height of a picture.
• Letter Box
Scales a picture to fit the projector’s native resolution in its 
horizontal width and resizes the picture height to the 3/4 of the 
projection width. This makes a picture greater than the screen 
height. The top and bottom edges of the displayed picture are 
cropped. This suits the contents which are produced in letter 
box format (with black bars on the top and bottom).
Sound Mode
Sound Mode utilizes MaxxAudio sound enhancement 
technology, which incorporates Waves’ algorithms to deliver 
great effects of the bass and treble and provide you with 
immersive cinematic audio experience. The following preset 
sound modes are provided: Motion Video, Music, and 
Cinema.
If the Mute function is activated, adjusting “Sound Mode” will 
turn off the Mute function.

the volume being output from the audio output jack.
If the Mute function is activated, adjusting “Volume” will turn 
off the Mute function.
Mute
Select On to temporarily turn off the projector’s built-in 
speakers or the volume being output from the audio output jack.
