• Upon modifying a format value, click Evaluate. The Format Editor applies the new
value to the timing algorithm and updates any values dependent on the value you
entered (or changed).
For example, to change the horizontal resolution to 660, enter the value in the
Active field under Pixels in the Horizontal area, and then click Evaluate. The result
is shown below.
Notice that the Format Editor has calculated and written values to the Blank and
Period fields as indicated by the red calculator ( ) symbol. Although the Period
value has not changed, the Format Editor still indicates it is a calculated value by
displaying the red calculator.
When there is a relationship between values (for example, Active, Blank, and
Period fields), and you want to change a value that was calculated, you must delete
the associated non-calculated field value before entering a value in one of the
calculated fields. For example, to change the Blank value and calculate new Active
and Period values, you must delete the value in the Active field, change the value
in the Blank field, and then click Evaluate to display updated values.
