Runco VX-80d, VX-40d, VX-50d manual Adjust Pixel Tracking before Pixel Phase, Recommended see below

Installation

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.

Adjust “Pixel Tracking” before “Pixel Phase.”

Note

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.

H-Position:This option moves the image right or left within the area of available pixels.

V-Position:This option moves the image up or down within the area of available pixels.

The values shown represent where the approximate center of the

Note 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.

Image Settings Menu ➤ Use options in the Image Settings 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).

Contrast: “Contrast” increases or decreases the perceived difference between light and dark areas of your image (0-100). For best results, keep it under 50. If contrast is set too high, the light parts of the image lose detail and clarity. If set 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).

Brightness: “Brightness” 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.
