Introduction

Low Power Consumption

The LCD1280 has been designed with NEC’s IPM™ (Intelligent Power Manager) System. When utilized with an Energy Star system or video card, the LCD1280's IPM System is an innova- tive power saving utility that complies with both the EPA’s Energy Star requirements and Europe’s NUTEK’s power man- agement requirements.

With a maximum power consumption of only 50 watts in its on mode, the LCD1280 monitor consumes up to 50% less power and emits less heat than conventional CRTs.

In its power saving mode, the LCD1280 consumes less than 8 watts. All this translates into energy savings, envi- ronmental protection, reduced emissions and reduced air conditioning costs of the work environment.

The LCD1280 monitor follows the Video Electronics Standard Association (VESA) approved DPMS power-down signaling method. VESA’s Display Power Management Signaling (DPMS) method which is endorsed by the EPA is the power-down process a system should use to communicate to the monitor to save power. Power-down functions can only be utilized with an Energy Star system or video card which adheres to the VESA DPMS standard. By using the monitor’s horizontal and vertical SYNC signals, the monitor can be prompted into the

different IPM modes. The following is the description of the LED indicator for the IPM power saving modes:

Mode	LED Indicator	Power Consumption
ON	Green	Typical: 45 watts
Stand By & Suspend	Amber	Typical: Less than 8 watts
Power Switch, OFF	No Light	No Power Used

ErgoDesign™

The LCD1280 utilizes NEC’s ErgoDesign philosophy to make the panel more comfortable and easy to use. The panel’s power and brightness control are positioned within easy reach, and the tilt base adjusts to each individual’s preferred angle of vision. The LCD1280 monitor’s cabinet design and aesthetics look good from all angles.

Reduced Emissions

Incorporating NEC’s own Reduced Magnetic Field™ tech- nology, the LCD1280 has minimal field emissions and follows the strictest magnetic field, alternating electric field and electro-static recommendations of the Swedish Board for Technical Accreditation, or SWEDAC (previously known as MPR, National Board for Measurement and Testing). The LCD1280 conforms to SWEDAC MPR 1990:8 (MPR II) Testing Methods for Emissions. These standards are the most restrictive guidelines in the world.
