Disabling the password function
To disable password protection, go back to the SYSTEM SETUP: Advanced > 
Security Settings > Change Security Settings > Power on Lock menu after 
opening the OSD menu system. Select Off by pressing 
/
. The message 'INPUT 
PASSWORD' displays. Enter the current password. 
• 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.
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. 
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
 
 for details.
The native display resolution 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 
 for details.
