Technical Features

Preset and user modes

When the monitor receives an input signal, it automatically matches the signal to one of the factory preset modes stored in the monitor’s memory to provide a high quality picture at the center of the screen. (See page 20 for a list of the factory preset modes.) For input signals that do not match one of the factory preset modes, the digital Multiscan technology of this monitor ensures that a clear picture appears on the screen for any timing in the monitor’s frequency range (horizontal: 30 – 130 kHz, vertical: 48

–170 Hz). If the picture is adjusted, the adjustment data is stored as a user mode and automatically recalled whenever the same input signal is received.

Note for Windows users

For Windows users, check your graphics board manual or the utility program which comes with your graphics board and select the highest available refresh rate to maximize monitor performance.

Troubleshooting

Before contacting technical support, refer to this section.

If thin lines appear on your screen (damper wires)

The visible lines on your screen especially when the background screen color is light (usually white), are normal for the Trinitron monitor. This is not a malfunction. These are shadows from the damper wires used to stabilize the aperture grille. The aperture grille is the essential element that makes a Trinitron picture tube unique by allowing more light to reach the screen, resulting in a brighter, more detailed picture.

Power saving function

This monitor meets the power-saving guidelines set by VESA and ENERGY STAR. If no signal is input to the monitor from your computer, the monitor will automatically reduce power consumption as shown below.

Power mode	Power consumption	! (power)
		indicator
normal	≤ 135 W	green
operation
active off*	≤ 3 W	orange
(deep sleep)**
power off	Approx. 0 W	off

*When your computer enters power saving mode, the input signal is cut and NO SIGNAL appears on the screen before the monitor enters active

off mode. After a minute, the monitor enters power saving mode. **“Deep sleep” is power saving mode defined by the Environmental

Protection Agency.
