Pixel Phase: Adjust pixel phase when the image (usually from an RGB source) still shows
shimmer or “noise” after pixel tracking is optimized. Pixel phase adjusts the phase of the
pixel sampling clock relative to the incoming signal.
For best results, use a good test pattern such as a smooth gray consisting of a clear
pattern of black and white pixels, or a similar “half on, half off” graphic image. Adjust the
slidebar until the image stabilizes and each pixel is clearly defined. You may notice that
you can stabilize the image at more than one point; that is, you may find that the image
appearance at “11” is identical to the image appearance at “38.” Use either setting in such
cases. If some shimmer from a video or HDTV source persists, use the “
Filter” control in
the Image Settings menu (described later) to remove high-frequency noise from the signal.
Horizontal Shift: This option moves the image right or left within the area of available
pixels.
Vertical Shift: This option moves the image up or down within the area of available
pixels.
Picture Quality Menu Use options in the Picture Quality menu to alter your image without affecting its size or
position. Changes made in this menu are applied immediately and saved when you exit
the menu. Options not available for the projector model or source are disabled and appear
dim (gray).
White Level (Contrast): “White Level” increases or decreases the perceived difference
between light and dark areas of your image (0-100). For best results, keep it under 50. If
the White Level is too high, the light parts of the image lose detail and clarity. If it is too
low, the light areas will not be as bright as they could be and the overall image will be dim.
For best results, start with a low value and increase so that whites remain bright but are
not distorted or tinted and that light areas do not become white (“crushed”).
Black Level (Brightness): “Black Level” increases or decreases the amount of black in
the image (0-100). For best results, keep close to 50. Start with a high value and decrease
so that dark areas do not become black (“crushed”). Conversely, high brightness changes
black to dark gray, causing washed-out images.
Gamma: “Gamma” is a global setting that determines how gray shades are displayed
between minimum input (black) and maximum input (white) for all signals. The normal
gamma setting of 2.2 is correct for virtually all signals and conditions. If excess ambient
light washes out the image and it becomes difficult or impossible to see details in dark
areas, lower the gamma setting to compensate.
Adjust “Pixel Tracking” before “Pixel Phase.”
The values shown represent where the approximate center of the
image lies in relation to the total number of pixels available
horizontally or vertically. This varies widely according to the signal;
watch the image while adjusting.
