Signal Sampling
To optimize signal sampling settings, select the analog input (see
figure 34
,
2
, on the
previous page). Enter a value within the Min and Max values displayed to the right of each
adjustable setting (see figure 38,
6
) or click the Up or Down arrows).
NOTE: An asterisk beside a chosen value for a signal sampling setting indicates it is the
default value for the applied video signal.
2
Horizontal Start
– Defines the number of pixels from the start of the horizontal line
where active video begins.
3
Vertical Start – Defines the number of lines from the start of the vertical line where
active video begins.
4
Total Pixels – The total number of pixels in a horizontal line, including blanking on both
sides of the active video area (active video, horizontal sync width, back porch, and front
porch). The default value is determined by the source input. Values are adjusted from
the default value by ±255.
5
Pixel Phase – The timing of digital sampling by the scaler. Sampling at the optimum
pixel phase results in a bright, stable output and maximizes the contrast between pixels.
A good image for phase adjustment has adjacent black and white pixels.
