Eizo Nanao Corp will release a color wide LCD monitor equipped with a presence sensor.

Designed for use in offices, the monitor detects the presence of a person with an infrared sensor. And it shifts to the power saving mode when it finds the user leaving his or her desk and automatically resumes normal operation when the user returns.

The product comes in two types, the FlexScan EV2023W-H and the FlexScan EV2303W-T. The former is a 20-inch model with a resolution of 1,600 x 900, and the latter is a 23-inch model with 1,920 x 1,080 resolution.

The typical power consumption of the former model is 25W, and that of the latter model is 18W. In the power saving mode, the power consumption of the both models is 0.7W or lower.

The "EcoView Sense," a power saving function based on the presence sensor, detects objects within a 120cm range from the sensor unit by using an infrared sensor installed on the lower part of the front face of the monitor. The monitor shifts to the power saving mode when it determines that nobody is in the detection range for 40 seconds.

In order to avoid malfunction in small offices or in similar situations, the monitor checks the fluctuations in the detected values. And the monitor judges that the user has left the desk when the fluctuation in the detected value is lower than the predetermined level. To discriminate a person from a chair, etc, an object that does not move for one minute or longer is determined to be a still object even if it is in the 120cm range.

From the perspective of environmental friendliness, the product has an improved recycling efficiency and is compliant with "TCO Displays 5.0," the latest version of an international environmental standard, according to Nanao.

Also, the new product features a thin and light monitor unit. Each model has a monitor unit that is approximately 40% lighter than that of the existing model. Nanao reduced the number of sheet metal parts and increased the number of ribs in the resin parts to maintain the strength.

Furthermore, the company adopted new stand mechanisms called the "FlexStand" and the "TriStand." The FlexStand mechanism adopted for the EV2023W-H has the "world's largest class" height adjustment range of 225mm, according to Nanao. The mechanism has a tilt angle of 30° and a horizontal rotation angle of up to 172°. It can be vertically rotated as well.

The TriStand mechanism adopted for the EV2303W-T has a height adjustment range of 60mm, a tilt angle of 25° and a horizontal rotation angle of up to 172°. The EV2023W and the EV2303W respectively employs the vertical alignment (VA) and twisted nematic (TN) driving methods for the LCD panel.

Although there are no manufacturer's suggested retail prices, the direct sales prices of the EV2023W-H and the EV2303W-T are ¥37,800 (approx US$385) and ¥44,800 (both including tax). They will be released May 21, 2009.
