The image will be centered and displayed as large as possible depending on the source type and projector model: •A video image or 4:3 graphic image is enlarged to fill the screen height, centered between black side bars. •A 5:4 graphic image is enlarged to fill the screen height and is centered between black side bars. •An anamorphic (16:9) image fills the whole screen. •Full Size: Select Full Size to use all pixels for displaying the image, regardless of source or original aspect ratio. Incoming source material having a different aspect ratio than the projector will be stretched to fill the display. •Full Width: Select Full Width to fill the projector’s display from left-to-right without changing the original aspect ratio of the image. Depending on the source, data at the top and bottom may be discarded (cropped), or the display may have black borders at the top and bottom (called “letterbox”). •Full Height: Select Full Height to fill the display from top-to-bottom. Depending on the source, this may create borders. •Anamorphic: Select Anamorphic to display an anamorphic image in its native 16:9 aspect ratio. The image will fill the whole screen. Size: “Size” controls both the image width and height in tandem, maintaining the current aspect ratio (proportion) of the displayed signal data. Height: “Height” adjusts the image height while keeping the width constant. Use this setting to change the aspect ratio of the display. Pixel Tracking: Steady flickering or several soft vertical stripes or bands across the entire image indicates poor pixel tracking. Proper pixel tracking helps ensure that the image quality is consistent across the screen, that aspect ratio is maintained, and that pixel phase can be optimized (see below). Tracking determines the frequency of the pixel sampling clock, indicated by the number of incoming pixels per line, so that all pixels generated by a particular source are sampled. By default, the projector samples at the correct frequency for most sources. 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 vertical stripes broaden to the point where one large stripe fills the image. If the image still exhibits some shimmer or noise, adjust Pixel Phase (described below). 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. Note Adjust “Pixel Tracking” before “Pixel Phase.” 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. Note 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. Picture . Quality Menu 1. White Level 50.02. Black Level 50.03. Gamma 2.24. Filter Off5. Sharpness 06. Noise Reduction 07.

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”). Note If the environment lighting changes, an adjustment of Gamma is recommended (see below). 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...
