NOTE: When certain RGB signals are first connected, the projector may not initially 
recognize them as RGB and will incorrectly decode their color information as YPbPr 
(video). These signals can include: 
• RGB signals in NTSC, PAL, SECAM frequency ranges 
• Scan-doubled sync-on-green. 
• Scan-quadrupled sync-on-green. 
For these signals, change the Color Space to RGB, then define a new channel for 
future use.

NOTE: Generally, use “Auto” for all instances EXCEPT: 1) a poor quality input 
signal or 2) a black-and-white video signal. In order to detect and display such 
signals, select the relevant standard from the list. 
INPUT VIDEO BLACK: This control 
compensates for incoming elevated black 
levels present in certain video signals, and 
ensures that blacks in the display are 
neither crushed (i.e., where dark grays appear black) nor excessively elevated...

and blacklevels for each of 
the three colors, red, green 
and blue—ensure that 
images from analog sources 
other than decoded video 
have maximum contrast 
without crushing black or 
white. By default (and in an 
“Auto Setup”), the projector 
automatically determines 
the best input levels by 
monitoring image content and adjusting the controls appropriately—further 
adjustment is typically not required...

3.  Confirm that you are using an analog source not connected to INPUT 3 or 
INPUT 4, as Input Levels are not applicable for digital sources or sources 
going through the decoder. A grayscale is recommended. 
4.  If the blacks and/or whites appear OK, input levels do not need 
adjustment. If black levels are too high (and/or whites are too low, which 
is rare), you likely have a noisy source that is producing skewed input 
levels. Continue with Step 5....

2.  Display one primary color. NOTE: Selecting Auto Color Enable ensures the 
correct color is displayed for each setting.  
3.  For the current color, adjust its corresponding “Blacklevel” slidebar just until 
a single band of black appears at one edge of the screen. This band represents 
the first band of the grayscale pattern, which should be 100% black. Do not 
adjust too far. 
4.  With the same color still active, adjust its corresponding “Input...

GAMMA TABLE: This control applies a default video or graphics gamma table or 
“curve” to your images, controlling the intensity of midlevel colors and producing 
maximum contrast, brightness and color 
performance. As shown at right, the 
graphics curve is a simple power curve 
while the video curve has a linear segment 
near black to compensate for increased 
blacklevels typical of video signals. 
Although the projector automatically 
applies either...

and utilize different combinations of the projector’s original native color primaries to 
produce a “coloration” or cast (reddish or bluish) in images—the lower the 
temperature, the more reddish the cast; the higher the temperature, the more bluish 
the cast. Note that the slidebar is enabled only if you have a source connected and 
have selected “Color Temperature” in the adjacent “Select Color Adjustment” pull-

more time for shutters in 3D glasses to open/close, ensuring that each eye sees the 
full display intended for it. Symptoms of cross-talk and/or color artifacts can indicate 
need for adjustment. The Dark Interval range of adjustment depends on the vertical 
frequency of your source—the higher the frequency, the smaller the range.

typically “global” settings applied regardless of the type of source your are using. 
This characteristic is identified with the
