As such, the settings are not permanently stored and may be inadvertently deleted by the user.
4 Alignment and Adjustments 4-1-1 (i) BRIGHTNESS AND CONTRAST Unless otherwise specified, adjust control volumes: Brightness: Maximum Contrast: Maximum 4-1-2 Required Equipment Note: The signal cable connector which includes the 3-wire cable must connect to the monitor. If you use Setup 2 (PC only, no signal generator) you can only make adjustments to the signal timing available on that computer system. To make corrections to all factory timings requires the use of an additional signal generator.
4 Alignment and Adjustments 4-2 Display Control Adjustments 4-2-1 Centering 4-2-1 (d) VERTICAL POSITION ADJUSTMENT Centering means to position the center point of the display in the middle of the display area. Horizontal size and position and vertical size and position control the centering of the display.
