Installation
Do not install or leave the monitor:
• In places subject to extreme temperatures, for example near a radiator, heating vent, or in direct sunlight. Subjecting the monitor to extreme temperatures, such as in an automobile parked in direct sunlight or near a heating vent, could cause deformations of the casing or malfunctions.
• In places subject to mechanical vibration or shock.
• Near any equipment that generates a strong magnetic field, such as a TV or various other household appliances.
• In places subject to inordinate amounts of dust, dirt, or sand, for example near an open window or an outdoor exit. If setting up temporarily in an outdoor environment, be sure to take adequate precautions against airborne dust and dirt. Otherwise irreparable malfunctions could occur.
Handling the LCD screen
• Do not leave the LCD screen facing the sun as it can damage the LCD screen. Take care when you place the monitor by a window.
• Do not push on or scratch the LCD screen. Do not place a heavy object on the LCD screen. This may cause the screen to lose uniformity or cause LCD panel malfunctions.
• If the monitor is used in a cold place, a residual image may appear on the screen. This is not a malfunction. The screen returns to normal as the temperature rises to a normal operating level.
• If a still picture is displayed for a long time, a residual image may appear for a while. The residual image will eventually disappear.
• The LCD panel becomes warm during operation. This is not a malfunction.
About the bright points of light or black dots
Bright points of light (red, blue or green) or black dots may appear on the LCD screen. This is not a malfunction. The LCD screen is made with high­precision technology and more than 99.99% of the picture element is intact. However, some of the picture element may not appear or some of the picture element may appear constantly.
Replacement of the fluorescent tube
A specially designed fluorescent tube is installed as the lighting apparatus for this monitor. If the screen becomes dark, unstable, or does not turn on, replace the fluorescent tube with a new one. Consult your Sony dealer when replacing the fluorescent tube.
Maintenance
• Be sure to unplug the power cord from the power outlet before cleaning your monitor.
• Clean the LCD screen with a soft cloth. If you use a glass cleaning liquid, do not use any type of cleaner containing an anti-static solution or similar additive as this may scratch the LCD screen’s coating.
• Clean the cabinet, panel, and controls with a soft cloth lightly moistened with a mild detergent solution. Do not use any type of abrasive pad, scouring powder, or solvent, such as alcohol or benzine.
• Do not rub, touch, or tap the surface of the screen with sharp or abrasive items such as a ballpoint pen or screwdriver. This type of contact may result in a scratched picture tube.
• Note that material deterioration or LCD screen coating degradation may occur if the monitor is exposed to volatile solvents such as insecticide, or if prolonged contact is maintained with rubber or vinyl materials.
Transporting
• When transporting, first disconnect all cables from the monitor, then grasp the monitor with both hands to carry it. Be careful when transporting the monitor, if dropped it may cause injury or damage.
• When you transport this monitor for repair or shipment, use the original carton and packing materials.

DPMS defines three power saving states according to the state of the sync signals supplied from the computer. This monitor’s power consumption is input at approximately 3 W in all of these states if the power saving function is set to ON. When your computer enters in the power saving mode, the input signal is cut and NO INPUT SIGNAL appears on the screen. After a few seconds, the monitor enters power saving mode.
* “Sleep” and “deep sleep” are power saving modes defined by the
Environmental Protection Agency.
Note
The power saving function may not work normally if sync signals other than those listed above are supplied. In such a case, set the power saving function to OFF.
Automatic picture quality adjustment function
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 Appendix for a list of the factory preset modes.) For input signals that do not match one of the factory preset modes, the automatic picture quality adjustment function of this monitor automatically adjusts the phase, pitch, and picture position, and ensures that a clear picture appears on the screen for any timing within the monitor’s frequency range (horizontal: 30 – 61 kHz, vertical: 48 – 85 Hz). Consequently, the first time the monitor receives input signals that do not match one of the factory preset modes, the monitor may take a longer time than normal for displaying the picture on the screen. This adjustment data is automatically stored in memory so that next time, the monitor will function in the same way as when the monitor receives the signals that match one of the factory preset modes. In all modes, 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 on the adjusting the phase
If the automatic picture quality adjustment function is activated, the picture moves slightly whenever the monitor receives the input signal, regardless of the stored adjustment.
Note
While the automatic picture quality adjustment function is activated, only the power switch, and INPUT button will operate.
