Channel
Select a specific source setup (channel) defined and stored in projector memory. Once you enter a two-digit
channel number (or, if there is a list displayed, highlight it and press
E
NTER
), the display will automatically
change and update according to the numerous setup parameters defined for that channel.
NOTE:
A new channel

key behavior during a presentation depends on whether or not the Display Channel List
option is enabled in the

menu. You can select to use a scrollable list of channels when
you press

or you may prefer to enter the desired channel number “blind”, i.e., without on-screen
feedback.
Slot 1, 2, 3, 4
Press to display the next active input on the card in the slot.
Input
Displays all inputs in all slots, both active and inactive. Scroll through the list to select an input for the main
image. Press Input again to show the list and select the picture-in-picture (PIP) image.
PIP
Turns PIP ON or OFF.
Swap
Swaps the main and PIP images.
Contrast
Changes the level of peak white in your images. Use

until you reach the desired level
of cont
rast—for best results, start low and increase so that whites remain bright but are not distorted or tinted
and that light areas do not become fully white (i.e., “crushed”). Conversely, low contrast causes dim images.
Bright
Increases or decreases the black level in the image. Use

RROW

until you reach the desired
level of brightness. For best results, start high and decrease so that dark areas do not become fully black (i.e.,
“crushed”). Conversely, overly high brightness changes black to dark grey, causing washed-out images.
Gamma
Determines how grey shades are displayed between minimum input (black) and maximum input (white) for a
given amount of signal. The proper setting helps maintain optimized blacks and whites while ensuring a
smooth transition for the “in-between” values utilized in greys. Unlike brightness and contrast controls, the
overall tone of an image can be lightened or darkened without changing the two extremes and your images will
be more vibrant yet with good detail in dark areas when using the Gamma control.
The nominal setting for Gamma Correction of 0 is correct for most signals and conditions. If excess ambient
light washes out the image and it becomes difficult or impossible to see details in dark areas, increase the
gamma correction setting to compensate.
