startup logo is projected.
(If necessary) Rotate the focus ring to adjust the image clearness.
To turn off the ring tone, see Turning off the Power On/Off Ring Tone on page 38 
for details.
If the projector is still hot from previous activity, it will run the cooling fan for approximately 90 seconds 
before energizing the lamp.
3. If the projector is activated for the first 
time, select your OSD language following

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 displays. 
2. Press / until your desired signal is selected 
and press MODE/ENTER.
Once detected, the selected source information 
will display 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).
•  The native display resolution of this projector is in a 4:3 
(MX666+)/16:10 (MW665+) 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 29 for details.
•  Firewall in the PC must be switched off to allow USB Display to work.

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.
