Advanced Power Saving Mode

1. Background

The traditional monitors have the function of electricity-saving dormancy. Bu t the interval of dormancy is difficult to decide. If the interval is long, the purpose of saving electricity can not be achieved. While if the interval is short, y our computer and LCD monitor will be dormant often. When the LC D monitor becomes dormant, the back lights w ill be turned off immediately. The frequent turning-on and turning-off of lights will result in the lightness being uneven and even, shortening the life of the lights.

2. Our solution to the dilemma – Monitor the Life-Extension function

In view of that, we have designed the function of Monitor Life-Extension. Once you s elect the option of “Advanced

Power Saving Mode” in the OSD menu, and then you ca n not only save electricity, but extend the life of the lights.

3.Working principle of the Monitor Life-Extension function

To minimize the impact of frequent turn-on and turn-off of L CD monitor, the Life-Extension function decreases the electricity supplied to the back-light of LCD monitor gradually , instead of cutting it off right away when the P C enters sleeping or off mode. Please see the following comparison graphics for details.

* Advanced Power Saving Mode (with Monitor Life-Extension function)

This “Slow-Start-n-Delay-Off” approach minimizes the transit of electricity and temperature caused by the turning-on and turning-off of the LCD monitor. Therefore, the decay of backlights of TFT -LCD ca n be controlled at the certain level which is much less than it was.

4. The side effect of the Monitor Life-Extension function (why not preset Advanced Power Saving Mode as default?)

According to the request of EP A (US Environmental Protection Agency) to power management of monitors, the power consumption of the monitor must go down to below 3 watts within 3 seconds after the monitor s goes into power s aving mode. Bu t the Life-Extension function decreases the electricity supplied to the backlights of LCD monitor gradually.Therefore, the Monitor Life-Extension function has a conflict with the requirement of E PA in the first 7 minutes after entering sleeping mode. Even though,comparing the advantage s o f both conditions, we still recommend you strongly set your monitor to Advance d Power Saving mode.
