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 (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 
remote control. A source selection bar 
displays.  
						

							Operation 37 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).
• The input signal type effects the options available for the Picture Mode. 
See Selecting a picture mode on page 40 for details.
• The native display resolution of this projector is in a 16:10 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 
Selecting the aspect ratio on page 38 for details.
Changing Color Space
In the unlikely event that you connect the projector to a DVD player via the 
projectors HDMI input and the projected picture displays wrong colors, please

							Operation
38The picture can only be navigated after the picture 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.
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.
•Using the OSD menu
1. Press Menu/Exit and then press  /  until the 
DISPLAY menu is selected.
2. Press
  to select Aspect Ratio.
3. Press  /  to select an aspect ratio to suit the format of the video signal and 
your display requirements.
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 adjusents.

							Operation 39 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 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, like high definition TV, 
as it displays them with out aspect alteration.
