Pioneer PDP 427CMX technical manual Auto, To the brightness of the room

[Applicable only when a PDA-5003/PDA-5004 is installed] Menu Mode

12) Energy Saving Setting

This is a function that reduces power consumption and reduces deterioration of the panel. This setting controls the brightness of the screen according to the input signal.

•To make the screen bright and easy to see: Set ‘ENERGY SAVE: STANDARD1, STANDARD2 (STANDARD)*’.

•To perform control according to the brightness of the room and to adjust the screen according to the surroundings: Set ‘ENERGY SAVE: AUTO’.

•To reduce power consumption: Set ‘ENERGY SAVE: MODE1, MODE2’.

•To reduce deterioration of the panel such as burning: Set ‘ENERGY SAVE: MODE 3’.

•To temporarily turn off the present screen display: Set ‘ENERGY SAVE: MUTE‘ and press the MENU button. Image mute starts at the same time that the menu disappears.

Factory setting: STANDARD1 (STANDARD)*

Differences in video reproduction by energy saving settings (illustration)

For this kind of input signal

(As a standard)

When the white window is displayed, the peak brightness is decreased as shown below.

• MODE1: Decreased about 50%

• MODE2: Decreased about 60%

• MODE3: Decreased about 75%

STANDARD1, STANDARD2 (STANDARD)*

For an overall bright video, there is no change (Figure on the left).

For an overall dark video, the peak brightness is reproduced even brighter (Figure on the right).

AUTO	The brightness is automatically changed within the STANDARD (bright) to MODE2 (dark) range according
	to the brightness of the room.

MODE1, MODE2

MODE3

MUTE	It temporarily shuts off the screen that is displayed.
	To cancel MUTE, press the MENU button, INPUT button etc.

Power consumption is lowered by reducing the brightness of an overall bight video (Figure on the left).

Similar to in the STANDARD setting, an overall dark video is peak brightness is reproduced even brighter (Figure on the right).

The peak brightness in MODE2 is decreased by a set amount with respect to that in MODE1, however it is reproduced brighter than in MODE3.

Input signal graduation is not controlled but reproduced accurately. Deterioration of the panel due to burning is reduced since the peak brightness of an overall dark video is not increased.
