Securing the projector
Using a security cable lock
The projector has to be installed in a safe place to prevent theft. Otherwise, 
purchase a lock, such as a Kensington lock, to secure the projector. You can 
locate a Kensington lock slot on the left side of the projector. See 
Kensington anti-theft lock slot on page 12 for details. 
A Kensington security cable lock is usually a combination of key(s) and a lock. 
Refer to the lock’s documentation for finding out how to use it.

Switching input signal
The projector can be connected to multiple devices at the same time. 
However, it can only display one full screen at a time. 
Be sure the Quick Auto Search function in the Source menu is On 
(which is the default of this projector) if you want the projector to 
automatically search for the signals.
You can also manually cycle through the available input signals.
1. Press SOURCE on the projector or press input source directly from 
the remote control. A source selection bar displays. 
2. Press ▲/▼ until your desired signal is selected and press MODE/
ENTER.
Once detected, the selected source information will display on the 
screen for seconds. If there is multiple equipment connected to the 
projector, repeat steps 1-2 to search for another signal.
•  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).
•  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 Selecting the aspect 
ratio on page 36 for details.
Changing Color Space
In the unlikely event that you connect the projector to a DVD player via the 
projector’s HDMI input and the projected picture displays wrong colors, 
please change the color space.

highlighted.
2. Press ▼ to highlight Color Space Conversion and press ◄/► to 
select the setting.
This function is only available when the HDMI input socket is in use.

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, 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 signal. 
To change the projected image ratio (no matter what aspect the source is):
•  Using the remote control
1. Press Aspect to show the current setting.
2. Press Aspect repeatedly to select an aspect ratio to suit the format of 
the video signal and your display requirements. 
						

							Operation37
•  Using the OSD menu
1. Press MENU/EXIT and then press ◄/► until the Display menu is 
highlighted.
2. Press
 ▼ to highlight Aspect Ratio.
3. Press ◄/► to select an aspect ratio to suit the format of the video 
signal and your display requirements. 
						

							Operation 38
About the aspect ratio
In the pictures below, the black portions are inactive areas and the white 
portions are active areas. OSD menus can be displayed on those unused 
black areas.
1.Auto: Scales an image 
proportionally to fit the 
projectors native resolution in 
its horizontal width. This is 
suitable for the incoming image 
which is neither in 4:3 nor 16:9 
and you want to make most use 
of the screen without altering 
the images aspect ratio.
2.Real: The image is projected as 
its original resolution, 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 
move the projector away from 
the screen to increase the image 
size if necessary. You may also 
need to refocus the projector 
after making these adjustments.3.4:3: 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 
images aspect DVD movies, as it 
displays them without aspect 
alteration.
4.16:9: 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.
5.16:10: Scales an image so that it 
is displayed in the center of the 
screen with a 16:10 aspect ratio. 
This is most suitable for images 
which are already in a 16:10 
aspect, as it displays them 
without aspect alteration.

Optimizing the image
Using Wall Color
In the situation where you are projecting onto a colored surface such as a 
painted wall which may not be white, the Wall Color feature can help 
correct the projected picture’s color to prevent possible color difference 
between the source and projected pictures.
To use this function, go to the Display > Wall Color menu and press ◄/► 
to select a color which is the closest to the color of the projection surface. 
There are several precalibrated colors to choose from: Light Yellow, Pink, 
Light Green, Blue, and Blackboard.
Selecting a picture mode
The projector is preset with several predefined picture modes so that you 
can choose one to suit your operating environment and input signal picture 
type.
To select an operation mode that suits your need, you can follow one of the 
following steps.
• Press MODE/ENTER on the projector repeatedly until your desired 
mode is selected.
•  Go to the Picture > Picture Mode menu and press ◄/► to select a 
desired mode.
1.Dynamic mode: 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.
2.Presentation mode: Is designed for presentation. 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 (dimly lit) environment.
5.3D mode: Is appropriate for playing 3D images and 3D video clips.
6.User 1/User 2 mode: Recalls the settings customized based on the 
current available picture modes. See Setting the User 1/User 2 mode 
on page 40 for details. 
						

							Operation 40
Setting the User 1/User 2 mode
There are two user-definable modes if the current available picture modes 
are not suitable for your need. You can use one of the picture modes (except 
the User 1/User 2) as a starting point and customize the settings.
1. Press MENU/EXIT to open the On-Screen Display (OSD) menu.
2. Go to the Picture > Picture Mode menu.
3. Press ◄/► to select User 1 to User 2.
4. Press ▼ to highlight Reference Mode.
This function is only available when User 1 or User 2 mode is selected up in 
the Picture Mode sub-menu item.
5. Press ◄/► to select a picture mode that is closest to your need.
6. Press ▼ to select a sub-menu item to be changed and adjust the value 
with ◄/►. See Fine-tuning the image quality in user modes below for 
details.
Fine-tuning the image quality in user modes
According to the detected signal type, and selected picture mode, some of 
the functions listed below may not be available. Base on your need, you can 
make adjustments to these functions by highlighting them and press ◄/► on 
the projector or remote control.
Adjusting Brightness
The higher the value, the brighter the image. 
And lower the setting, darker the image. 
Adjust this control so the black areas of the 
image appear just as black and that detail in the 
dark areas is visible.
Adjusting Contrast
The higher the value, the greater the contrast. 
Use this to set the peak white level after you 
have previously adjusted the Brightness 
setting to suit your selected input and viewing 
environment.
Adjusting Color
Lower setting produces less saturated colors. If the setting is too high, colors 
on the image will be overpowering, which makes the image unrealistic.
Adjusting Tint
The higher the value, the more reddish the picture becomes. The lower the 
value, the more greenish the picture becomes.
Adjusting Sharpness
The higher the value, the sharper the picture becomes. The lower the value, 
the softer the picture becomes.
