When Windows 7 puts my PC into the sleep mode & my Acer LCD monitor goes black, is the monitor actually powering down the lamps or is the PC just not sending it a signal to display?

Monitors go into a power savings mode when they detect a loss of signal. The PC drops the video signal in sleep mode and the monitor goes into power savings mode.

But what actually happens to the monitor in sleep or power saving mode?

Do the lamps actually shut off?

IOW if I go out shopping for an hour or two, is there any advantage in my turning off the monitor?

Hello Mike99, yes the lamps shut off in sleep mode. The monitor in in power saving mode so there is still a minute amount of power to it. This helps bring your display up more quickly when you wake the computer.
Turning the monitor off will save electricity, but maybe 7¢ a year.
