I know that refresh/sync rate cant be lowered because it would impact gameplay but what about using face/light/proximity sensor to dim or even turn off backlight or even lcd to save some energy while mage is regenerating mana somewhere. Other chars could use same feature to regen hp. Of course using this mode would be risky if we leave char in dangerous place or some pvper would happen

Also this could be used to cover sensor with paper sheet if boss comes in at work
