EnglishSwitching 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 wa nt the projector to automati cally 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. 
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 39 for details.
• The native display resolution of this projector is in a 4:3 aspect ratio (MP735 is 16:10). 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 37  for details.
Changing Color Space
In the unlikely event that you connect the projector to a DVD player via the projector’s
DVI-D  input and the projected pi cture displays wrong colors, please change the color 
space to  YUV or RGB .

EnglishAdjusting 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 pr ojection angle. To adjust the projector:
1. Press the quick-release button and lift the  front of the projector. Once the image is 
positioned where you want it, release the 
quick-release button to lock the foot in 
position.
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 projector is not placed on a flat surf ace 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 press the adjuster button  as it is close to the exhaust vent where hot 
air comes from.
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 upper left corner of the 
screen for 3 seconds. 
• The screen will be blank while AUTO is functioning.
• This function is only available when PC signal (analog RGB) is selected.

EnglishSelecting the aspect ratio
The aspect ratio is the ratio of the image width to the image height. For MP724 and 
MP727, the default aspect ratio is 4:3. And  for MP735, the default aspect ration is 16:10. 
Most analog TV and computers ar e 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 (n o matter what aspect the source is):
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.
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: 
MP724 and MP727:
 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.
MP735:
 Scales an image proportionally to 
fit the projectors nati ve resolution in its 
horizontal width and ve rtical height. This 
is suitable for the incoming image which 
is in 4:3, 16:9 or 16:10 and you want to 
make most use of the screen without 
altering the images aspect ratio.

resolutions, the projected image will 
display smaller than if resized to full 
screen. You could adjust the zoom setting 
or 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.
