Adjusting the projected image
Adjusting the projection angle
The projector is equipped 2 adjuster feet. These adjusters change the image height and 
projection angle. To adjust the projector:
Screw the adjuster feet to fine-tune the 
horizontal angle.
To retract the feet, screw the adjuster feet in a 
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 22 
for details.
Auto-adjusting the image
In some cases, you may need to optimize the picture quality. To do this, press AUTO 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 corner of the screen for 3 seconds.
This function is only available when PC signal (analog RGB) is selected.
Fine-tuning the image clarity
Sharpen the image by rotating the focus ring. 
Do not look into the lens while the 
light source is on. The strong light 
from the light source may cause 
damage to your eyes.
Be careful when you press the quick-
release button as it is close to the 
exhaust vent where hot air comes 
from.

							Operation 27
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. When starting up, the projector automatically searches for 
the available signals.
Be sure the Quick Auto Search function in the SOURCE menu is On if you want the 
projector to automatically search for the signals.
To select the source:
1. Press SOURCE on the projector or remote 
control. A source selection bar is displayed. 
2. Press / until your desired signal is selected 
and press MODE/ENTER.
If available, you can also select the source by 
pressing one of the Source buttons on the 
remote control.
Once detected, the selected source information 
will be displayed at the corner of 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 the projector’s native 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 28 for 
details.
•  Firewall in the PC must be switched off to allow QPresenter and USB Display to work.
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 to YUV.
To  d o  t h i s :
1. Press MENU/EXIT and then press  /  until the SOURCE menu is highlighted.
2. Press   to highlight Color Space Conversion and press  /  to select a suitable 
color space.
This function is only available when the HDMI-input port is in use.

also press   repeatedly until it is restored to the original size.
The picture can only be navigated after it is magnified. You can further magnify the picture 
while searching for details.
Selecting the aspect ratio
The “aspect ratio” is the ratio of the image width to the image height. Most analog TV and 
some 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 picture 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.
•  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 29
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 or vertical 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 
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.
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 some 
computer monitors, standard 
definition TV and 4:3 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 
colors 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 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 or remote control 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 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.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 30 for details.
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 1/2) 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 or 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.
