3D Control:
3D: allows you to enjoy 3D (stereoscopic) content. Your projector supports Auto, 
Top-Bottom, Frame Sequential, Frame Packing, Side-by-Side for controlling LCD shut-
ter glasses. In addition to the projector, you will need a pair of 3D shutter glasses, 3D 
content, and 3D compatible source. Ensure the glasses you choose are consistent with 
the synchronization mode you will be using.
3D Sync Invert: If the image appears to flutter, look odd or if the image depth looks off 
or you experience eye strain, turn this feature on to see if the image improves. 
Color
Color: adjusts a video image from black and white to fully saturated color. The color 
setting applies to video sources only.
Red/Green/Blue Gain: adjusts the gain of the red, green or blue channel of the image.
Red/Green/Blue Offset: adjusts the offset of the red, green or blue channel of the 
image.
Color Space: applies to computer and component video sources. 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 or choose either 
REC709 or REC601 for component video sources.
Color Temperature: changes the intensity of the colors. Select a listed relative 
warmth value.
Gamma: select the appropriate gamma from among Video, Film, Bright, and CRT.
Tint: adjusts the red-green color balance in the image of NTSC video images. The tint 
setting applies to NTSC video sources only.
White Intensity: increases the brightness of whites that are near 100%.
PC:
Force Wide: when this is off, the analog locking algorithms choose the standard mode 
resolution (4:3) as the preferred default resolution. When this is on, the analog locking 
algorithms choose wide mode resolution (16:10) as the preferred default resolution.
Phase: adjusts the horizontal phase of a computer source.
Prevent PC Screen Saver: prevents your computer from going into Screen Save 
mode. The projector must be connected to the PC via a USB cable for this feature to

is not syncing properly with the projector, select this option to help it to sync when 
connected to the projector.
Tracking: adjusts the vertical scan of a computer source.

Video:
Detect Film: determines whether the original source of the input video was film (pro-
gressive) or video (interlaced).

Set Black Level: analyzes the current input image and calculates an offset value which 
is then added to the analog to digital converter black level value. This ensures optimum 
black level for each analog source.

times in succession, the projector will automatically shut down. If you lose or forget 
your custom PIN, contact InFocus Technical Support.

power is saved and no image is shown. When the video source is again applied, the 
image is shown immediately.
Source
Auto Source: When this feature is On, the projector automatically finds the active

you must manually select one by pressing the 
Source button on the remote or keypad 
and selecting one from the displayed Source menu.
Power-up Source: determines which source the projector checks first for active
