SAMPLING MODE

Sets the color sampling mode for a digital signal to either YCbCr 4:4:4, RGB or YCbCr 4:2:2. The proper
sampling mode is determined automatically by the projector; you can override this setting.
•

FILM MODE DETECT

Enable or disable film motion detection. Only available for interlaced or segmented frame sources.
•

CHROMA/LUMA DELAY

Affects any incoming composite or S-video signal, delaying the luma signal (intensity) in relation to the
chroma (color). In the image, increasing the luma delay will move luma (seen as a shadow where colors
overlap) to the right slightly, with colors remaining in place. Decreasing this delay will move the shadow
slightly to the left. If necessary for your current source, adjust so that no shadows occur with adjacent colors.

• ADAPTIVE CONTRAST

Dynamically expands the contrast of the output image producing vibrant images with seamless response to
scene changes and fades. The slide bar adjusts the amount of adaptive contrast to apply, with a setting of “0”
producing no change. Adaptive contrast is disabled when the Dynamic Iris is operating in Dynamic mode.

• SPLIT SCREEN

This control allows a snap shot of the main image to be presented on the right side or lower part of the screen,
to allow evaluation of advanced image processing features. All resizing controls are honoured on both images.
However, image processing controls (such as, Detail, Sharpness, Noise Reduction and Adaptive Contrast) only
happen on the left side or top image. Changing inputs, channels or test patterns will disable this control. PIP
operation must be disabled prior to enabling this control.

NOTE:

Split screen cannot be used in conjunction

with either PIP or Tiling. Both PIP and Tiling must be disabled prior to enabling Split Screen control.

• RGB QUANTIZATION RANGE

This control defines the RGB quantization levels for digital DVI and HDMI inputs using the RGB colorspace.
Typically, graphics sources use the full range of levels for the given bit depth (i.e. 8-bit, 10-bit, 12-bit) and
consumer electronics (CE) products typically use a limited range of data within the given bit depth. This
control must be set to limited to correct the levels for those CE products that use the limited space. This adjusts
what is considered black and white levels in the image. As an example for 8 bit space, full range RGB uses
levels 0(black) to 255(white). Split Screen cannot be used in conjunction with either PIP or Tiling. Both PIP
and Tiling must be disabled prior to enabling the Split Screen control.

INPUT LEVELS - S

UBMENU

NOTES: 1)

Because the projector

automatically optimizes input levels for all
but the most unusual of sources, it is
recommended that only experienced users use
the Input Levels submenu.

Before

beginning, check that overall contrast and
brightness settings are near 50 and that color
temperature is properly set up on an internal
greyscale test pattern.
