It’s a good idea. Not just because it’s cool, but also because it’s green. We’re talking monitors that activate or deactivate based on the mere presence of humans. It’s almost alive. Or may seem that way. It’s how Eizo’s 20-inch FlexScan EV2023W-H and 23-inch EV2303W-T roll. They’ll save you energy and money. And maybe help you shed some of that some of that green guilt.

The built-in motion sensor on the monitor switches to standby mode when a human is not detected for 40 seconds. Aside from that, both of these monitors are pretty typical. You’ll get 1600 × 900 native resolution, 178-degree viewing angles, and a 3000:1 contrast ratio for the EV2023W and 1920 × 1080 native resolution, 160-degree viewing angles, and a 1000:1 contrast ratio for the EV2303W.

Both will be available on May 21, 2009 for about $385 and $455 respectively.
