• V Position: •This control adjusts the vertical position of the image within the
designated image area, up to 25 per cent of the image height up or down.
• H Position: This control adjusts the horizontal position of the image within the
designated image area, up to 25 per cent of the image width left or right.
• Phase (RGB or Component sources): This control adjusts the phase of the pixel
sampling clock relative to the incoming signal. Adjust the phase when an RGB or
Component image still shows shimmer or “noise” after Tracking has been optimized.
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. Use either setting in such cases.
• Tracking (RGB or Component sources): 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.
Adjust the Phase after adjusting Tracking (see below). If some
shimmer from a video or HDTV source persists, use the Noise
Reduction controls (described on page page 52) to remove
high-frequency noise from the signal.
