							Operation 28
Switching input signal
The projector can be connected to multiple devices at the same time. However, it can only 
display one at a time. 
When SOURCE on the projector control panel or the remote control is pressed, information 
of current signal and resolution will display at the lower right corner. Press SOURCE again 
to display  a source selection bar. You can manually press SOURCE repeatedly until your 
desired signal is selected or let the projector automatically search for the available signal.
Once detected, the selected source information 
will display at the lower right corner of the 
screen for 3 seconds. If there is multiple 
equipment connected to the projector, you can 
press the button again to search for another 
signal.
Be sure the Source Scan function in the 
Advanced menu is activated if you want the 
projector to automatically search the signals. See 
Source Scan (on) on page 43 for details.
If no input is detected after auto searching for 
two rounds, a message of No Signal will be 
shown on the screen.
The brightness level of the projected image will change accordingly when you switch between 
different input signals. Data (graphic) PC presentations using mostly static images are 
generally brighter than Video using mostly moving images (movies).
The input type affects the options available for the Application Mode. See Selecting a picture 
mode on page 31 for details.
Adjusting the projected image
Adjusting the projection angle
The projector is equipped with 1 quick-release adjuster foot and 1 rear adjuster foot. These 
adjusters change the image height and projection angle. To adjust the projector:
1. Lift the projector up and press the 
adjuster button to release the 
adjuster. The adjuster will drop 
into position and be locked.
Do not look into the lens while the lamp is 
on. The strong light from the lamp may 
cause damage to your eyes.
2. Screw the rear adjuster foot to fine 
tune the horizontal angle.
To retract the foot, hold up the projector while pressing the quick-release button, then 
slowly lower the projector. Screw the rear adjuster foot in a reverse direction.
If the screen and the projector are not perpendicular to each other, the projected image 
becomes vertically trapezoidal. To correct this situation, adjust the value of Keystone in the 
Picture menu, on the projector control panel, or on the remote control. See Correcting 
keystone on page 29 for details. 
						

							Operation 29
Auto-adjusting the image
In some cases, you may need to optimize the 
picture quality. To do this, press AU TO on the 
projector or remote control. Within 3 seconds, 
the built-in Intelligent Auto Adjustment 
function will re-adjust the values of Frequency 
and Clock to provide the best picture quality. 
The current source information will be displayed 
in the lower right corner of the screen for 3 
seconds. 
The screen will be blank while AUTO is 
functioning.
Fine-tuning the image size and clarity
Correcting keystone
Keystoning refers to the situation where the projected image is noticeably wider at either the 
top or bottom. It occurs when the projector is not perpendicular to the screen. 
To correct this, besides adjusting the height of 
the projector, you will need to manually correct 
it following ONE of these steps.
1. Press  Left3/Right 4 on the control panel of 
the projector to display the status bar labelled 
Keystone. Press Left 3 to correct keystoning at 
the top of the image. Press Right4 to correct 
keystoning at the bottom of the image.
2. Press /  on the remote control to 
display the status bar labelled Keystone, then 
press  to correct keystoning at the top of the 
image or press   to correct keystoning at the bottom of the image.
3. Press 6 MENU on the projector or MENU on the remote control. Go to 
 Pro-
Picture > Keystone
 and adjust the values by pressing Left 3/Right 4 on the projector or 
Left 3/Right 4 on the remote control.
1. Adjust the projected image to the size 
that you need using the zoom ring. 2. Then sharpen the image by rotating 
the focus ring.  
						

							Operation 30For example, 
Selecting the aspect ratio
The aspect ratio is the ratio of the image width to the image height. Most analog TV and 
computers are in 4:3 ratio, which is the default for this projector, and digital TV and DVDs 
are usually in 16:9 ratio.
With the advent of digital signal processing, digital display devices like this projector can 
dynamically stretch and scale the image output to a different aspect than that of the image 
input source. 
You can change the projected image ratio (no matter what aspect the source is) by entering 
 Pro-Picture >  Aspect Ratio. Select an aspect ratio to suit the format of the 
video signal and your display requirements. There are three aspect ratios available:
In the pictures below, the black portions are inactive areas and the white portions are active 
areas.
1.Native: The image is projected at its original aspect ratio, and resized 
to fit within the display area. For input signals with lower 
resolutions, the projected image will display smaller than if resized 
to full screen. You could adjust the zoom setting or move the 
projector towards the screen to increase the image size if necessary. 
You may also need to refocus the projector after making these adjustments.
2.4:3: Scales an image so that it is displayed in the center of the screen 
with a 4:3 aspect ratio. This is most suitable for 4:3 images like 
computer monitors, standard definition TV and 4:3 aspect DVD 
movies, as it displays them without aspect alteration.
3.16:9: Scales an image so that it is displayed in the center of the screen 
with a 16:9 aspect ratio. This is most suitable for images which are 
already in a 16:9 aspect, like high definition TV, as it displays them 
without aspect alteration.
16:9 aspect ratio is only sourced through the Component Video input when 
being fed an appropriate 16:9 aspect signal. See Connecting a Component Video source 
device on page 21 and Obtaining a preferred projected image size on page 14 for details.

Selecting a picture mode
The projector is preset with several predefined 
application modes so that you can choose one to 
suit your operating environment and input 
source picture type. To select a operation mode 
that suits your need, press MODE repeatedly 
until your desired mode is selected. The picture 
modes available for different types of signals are 
listed below.

2.Presentation Mode: Is designed for presentations. The brightness is emphasized in this 
mode to match PC and notebook coloring.
3.sRGB Mode: Maximizes the purity of RGB colors to provide true-to-life images 
regardless of brightness setting. It is most suitable for viewing photos taken with an 
sRGB compatible and properly calibrated camera, and for viewing PC graphic and 
drawing applications such as AutoCAD.
4.Cinema Mode: Is appropriate for playing colorful movies, video clips from digital 
cameras or DVs through the PC input for best viewing in a blackened (little light) 
environment.
5.Blackboard Mode: Is designed for educational use. Images are allowed to be projected 
on a dark background, such as a blackboard instead of a normal screen. It is most 
suitable for a well lit environment with a dark background for projection.
YPbPr/S-Video/Video Signal Input
1.Dynamic Mode: Is suitable for playing gamebox-based video games in a normal living 
room lighting level environment.
2.Standard Mode (Default): Is appropriate for viewing colorful movies, video clips
