Pixel phase

Use this option to adjust the phase of the pixel sampling clock relative to the incoming signal. It is used primarily for adjusting RGB inputs.

Adjust pixel phase when the image (usually from an RGB source) shows shimmer or “noise”. Pixel phase adjustment is done most effectively using a proper test pattern, such as a smooth gray consisting of a clear pattern of tiny black and white dots, or a similar graphic image, such as the Windows shutdown screen. Adjust this option until the image is stable and each dot is clearly defined. Using the numbers on the slidebar as a guide, you will notice that you can actually stabilize the image at more than one point—i.e., you may find that the image appearance at "11" is identical to the image appearance at "38", thus you can select either setting.

NOTE: 1) Adjust pixel phase after pixel tracking is properly set. 2) Not
