Section 3: Operation

•0 IRE – Used for DVD output with “enhanced black”, SECAM, most PAL standards, and Japanese NTSC.

•7.5 IRE – Used for most NTSC video signals.

For some types of video, you can override the setting. The control is disabled for other types of video (and all graphics sources). Generally, if black appears crushed when brightness = 50, choose “0 IRE”. If black appears excessively elevated, use “7.5 IRE”.

COLOR: This slidebar adjusts the color saturation level, i.e. the amount of color in a video image. Lower settings produce less saturated colors — for example a setting of “0” produces a black and white image. If the color level is too high, colors will be overpowering and unrealistic.

TINT: This slidebar adjusts the red/green color hue for true color reproduction of video and HDTV signals connected to Input 3 or 4. For best results, adjust tint while displaying an external test pattern—otherwise, it is recommended that tint remain at its default setting.

DECODER LUMA DELAY: This control 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.

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 grayscale test pattern. 3) There must be at least 2 consecutive white pixels present in the image for proper “Auto Input Level” function. Leave this control off after use.

Good RGB or input levels— that is, the drives 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 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.

However, for a very unusual source exhibiting one or more overly high blacklevels (typically caused by a noisy source causing blacklevel spikes), an experienced user
