Clock (VGA source)
This control sets 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. 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.
Phase (VGA source)
This control adjusts the phase of the pixel sampling clock relative to the incoming signal. Adjust the phase
when an image still shows shimmer or “noise” after the Clock setting has been optimized. Adjust the Phase
after adjusting Size
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 slide bar 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.
Input Resolution (VGA source)
If the vertical resolution is 768 or 1050, select the same resolution as the input resolution.
