3. Using the right adjustment knob, select the input (figure 3-7). Both the

5. When an input is configured for RGB, separate phasing adjustments for the
program and preview outputs can be made. To properly adjust the input
phase, the input should be the same resolution as the output of the SGS 408
and an alternating pixel pattern should be used.
Adjustments can only be made to the inputs currently displayed. The
values can be adjusted by pressing the button under the corresponding
direction. The available range is 0 to 31 and the default is 16 (figure 3-8).
It is important that input phase adjustments are done while viewing the
same input on both the program and preview outputs. This is to ensure that
both scalers are properly phased for each input.
