From the Input Menu, select Timing Adjust to display the Timing Adjust Menu, which
allows for adjustments to input sampling, sampling phase, pixel counts, and line counts.
Figure 4-13. Timing Adjust Menu (sample)
The following functions are available:
• Sampling — Select this function to change the sampling for the selected input.
Available values are: Off and On (default). Please note:
~ When 1:1 Sample is On, the system provides pixel-for-pixel sampling,
and generally better image quality.
~ When 1:1 Sample is Off, the system performs multiple samples for
every pixel, with a resulting “softer” image.
~ 1:1 Sample can only be changed for RGB and YP
b
P
r
analog inputs,
except analog NTSC or PAL formats.
~ All other input types have defined sample clocks that are inherently 1:1.
If the input is set to one of the other types, the value is [On].
• Phase A, Phase B — These two selections are advanced features which enable
you to adjust the sample phase of the system’s two scalers. Typically, they do not
need to be adjusted. Refer to the “Adjusting Sample Phase” section on page 45
for instructions.
The six “Total/Position/Active” values are initially filled in by the Auto Config command,
or set to their default values. You can adjust values for Analog RGB or YP
b
P
r
sources only.
Digital and decoded sources show values in brackets.
Please note:
• When 1:1 Sample is set to On, values are the true timing measurements for the
analog RGB or YP
b
P
r
inputs.
• When 1:1 Sample is set to Off, values represent the oversampling factor being
used.

Note
Timing Adjust Menu settings apply to analog input sources
only, except for NTSC and PAL sources. For all digital
sources and analog NTSC or PAL sources, these fields are
informational only and will be bracketed.
