Input Levels - Submenu - Christie J Series User Manual

• 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 colors pace. 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.

3.6.6 Input Levels - Submenu

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. 2) Before beginning, check that
overall contrast and brightness settings are near 50 and that color temperature is properly set up on an
internal gray scale test pattern. 3) See
Good RGB or input levels—that is, the drives and black levels 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 to obtain proper blacks or whites.
NOTE: This automatic adjustment requires at least 6-12 consecutive white pixels in the image. Without these
pixels, input levels may produce skewed colors, particularly in non-video images.
