When you get up to go somewheres else away from your monitor do you turn it off or do you let it go to sleep by itself or do you have it set to never sleep so it's just always on? Usually when i'm walking away for more than about 10 minutes i just turn the monitor off. With as hot as the monitor gets it seems to me that less time on the better, and with less hours on the backlight the longer it'll last. Or am i just fooling myself? What puts more wear and tear on the monitor, leaving it on, such as backlight lit and screen on or turn the whole thing off only to turn it back on a little later? With a 600 dollar price tag i'd like my 2407 to last as long as possible.
