If  the  password  is  correct,  the OSD menu returns to the Security Settings page with 
'Off' shown in the row of Power on Lock. You will not have to enter the password 
next time you turn on the projector.
If the password is incorrect, the password error message displays lasting for three 
seconds, and the message 'INPUT PASSWORD' displays for your retry. You can 
press MENU/EXIT to cancel the change or try another password.
Though the password function is disabled, you need to keep the old password in hand should 
you ever need to re-activate the password function by entering the old password.

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. 
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 MX750 is in a 4:3 aspect ratio while the native display 
resolution of MP780 ST 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 37
 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 
to YUV.
