Sharpness: changes the clarity of the edges of a video image. Select a sharp-
ness setting.
Color Space: This option applies to computer and component video 
sources (except 480i/576i). It allows you to select a color space that has been 
specifically tuned for the input signal. When Auto is selected, the projector 
automatically determines the standard. To choose a different setting, turn 
off Auto, then choose RGB for computer sources, choose either SMPTE240, 
REC709 or REC601 for component video sources.
Color Temperature: changes the intensity of the colors. Select a listed 
value, or select User and individually adjust the intensity of the red, green, 
and blue colors.
Video Standard: when set to Auto, the projector attempts to automatically 
pick the video standard based on the input signal it receives. (The video 
standard options may vary depending on your region of the world.) If the 
projector is unable to detect the correct standard, the colors may not look 
right or the image may appear “torn.” If this happens, manually select a 
video standard by selecting NTSC, PAL, or SECAM from the Video Stan-
dard menu. 
Active Iris: when on, the projector monitors the image brightness and mod-
ifies the light output if the image is dark, which improves black levels. In 
Presentation mode, it looks at peak brightness, in Theater mode it looks at 
average brightness.
Overscan: (video sources only) removes noise around the video image.
The following 4 options are for computer sources only (except M1-D signal): 
Phase: adjusts the horizontal phase of a computer source. 
Tr a c k i n g: adjusts the horizontal scan of a computer source.
Horizontal / Vertical Position: adjusts the position of a computer source.

Settings menuAudio: allows adjustments to the Volume. Also allows you to turn on and 
off the Internal speakers, and projector startup Chime.
Sources
: allows you to assign a particular input to a specific source key 
when using the Integrator remote. Also allows selection of a default Startup 
Source and enables or disables Autosource. 
Sources>Power-up Source: this determines which source the projector 
checks first for active signal during power-up. 
Sources>Autosource: When Autosource is not checked, the projector 
defaults to the source selected in Powerup Source. If no source is found, a 
blank screen displays. When Autosource is checked, Powerup Source deter-
mines which source the projector defaults to at power-up. If no signal is 
present, the projector checks the sources in order until a source is found or 
until power down. 
System>Rear: reverses the image so you can project from behind a 
translucent screen.
Ceiling: turns the image upside down for ceiling-mounted projection.
IR Receivers: turns individual IR receivers off or on to avoid environ-
mental interference.
Auto Power: When Auto Power is checked, the projector automatically 
goes into the startup state after the projector is powered on. This allows 
control of ceiling mounted projectors with a wall power switch.
Display Messages: displays status messages (such as “Searching”) in the 
lower-left corner of the screen.
Low Power: toggles between on and off. Turn it on to lower the light out-
put of the lamp. This also lowers the fan speed, making the projector qui-
eter.
PC Screen Saver Off: prevents your notebook computer from going into 
Screen Save mode. The projector must be connected to the PC via a USB 
cable for this feature to work.
