■ Resetting Adjustment
Clears the values set in marginal focus adjustment and returns the lens marginal
focus to the standard position.
In the [Install settings] menu, select [Professional settings] > [Marginal focus] >
[Reset] to reset the adjustment.
After the above window disappears, the values set in [Marginal focus] are cleared
and the lens marginal focus is returned to the standard position. A reset can be
applied regardless of whether [Marginal focus] is set to [On] or [Off].
• Setting [Marginal focus] to [Off] will not reset the setting value for marginal focus. Select
[Off] to preserve the setting value and prevent further adjustment.
• Even after resetting, the focus may be slightly off at the center and edges of flat
screens.
• If necessary, use marginal focus adjustment to bring the center and edges into focus.
