For all Horizontal “active area” fields, all units are measured in pixels:

•H Total — adjusts the total pixel count per line. This value cannot be adjusted if the input type is DVI / SDI.

For all Vertical “active area” fields, all unit are measured in lines.

•V Total — indicates the total line count per frame. This value is measured, and can never be adjusted. Its value will always be shown in brackets.

The PDS has two A-to-D converters, which are referred to as Phase A and Phase B in the Timing Adjust Menu. The sample phase value of each scaler can be changed by the Auto Config menu option, or set to the default value of 0 (zero). If required, advanced users can fine-tune the image by adjusting the sample clock phase of each scaler directly — but only for inputs whose “type” is analog.

Adjustment range: -16 to 15

Default: 0

Note

Auto Config will only show in the Sizing Adjust or Timing Adjust menu when the input source is analog, except for analog NTSC or PAL formats.

Use the following steps to adjust sample clock phase of each scaler, for inputs whose “type” is analog.

1.From the Input Menu, navigate to the Input Sizing Menu, and scroll to the Phase A or Phase B line.

2.In the Inputs Section, select an input whose “type” is analog.

3.TAKE the input to Program. The button lights solid.

4.Pend the same input for the next transition. In this mode, only one button will now be lit solid, and no buttons will be blinking.

5.On the Input Sizing Menu, note that one of the two Phase lines will be bracketed, and the other will be unbracketed. When you press TAKE, the brackets will switch positions. The un-bracketed line is the active scaler.

6.On the selected input, put up a Burst pattern. For example, if the source is a computer, use a program such as DisplayMate® to generate the pattern.

7.Scroll to the unbracketed Phase line, and press SEL.

8.Use the Adjust knob to tweak the burst pattern for the maximum visual clarity and a minimum amount of visual noise, then press SEL to accept the new value.

9.Press TAKE to activate the other scaler.

10.Repeat steps 7 and 8 for the other scaler.
