Powering down your monitors from your PC would definitely speed up your end-of-day workflow. Is it possible?
I was looking for answers on that matter a few months ago.
Then I realize how "First World Problem" this concern is since... you know.. moving my arm a few inches to the power button on the monitor isn't that big of a deal, after all.
I will admit, however, that if such option was possible, I would be happily using it.
I use an power strip to do that : http://www.belkin.com/us/F7C007-Belkin/p/P-F7C007/
It automatically senses when my PC is off and shutdowns both my monitors & my powered speakers.
I don't think the monitors are too power hungry when in standby, but the speakers didn't have a "low power" mode.
It sound's like he is looking for something that will shut down his monitor if his computer stays on. They do make "smart power strips" that will sense a change in voltage and turn on/off everything else. My issue is if you are worried about power consumption, why are you leaving your PC on? Standby on a monitor = off basically. Your running PC is using power. Set your PC to go in standby after 15 minutes and your monitor will follow. Best solution in my opinion.
He could also be looking for something to shut down his monitors for when he leaves and then later remote connects to this pc. I use G2MyPC at work and I know that when your remotely connected it does not black out the monitors but instead shows what your working on the screen. Now i havent checked the settings yet to see if there is an option to do this but this would make a valid reason for wanting to do this especially if your working with sensitive data and always forget to turn them off like I do.
I've tried using standby settings on my monitor but I had trouble with it turning off when I didn't want it to (not the system's or monitor's fault; I just have variable needs) and, occasionally, turning on in the middle of the night so I just now manually hit the power switch on the monitor when I'm done with it. For me, that proved to work best. I kill my monitor (poor monitor!) more to keep it from pumping heat into the room than to save electricity (it's amazing how much heat even an LCD can throw off) and so the light from it at night isn't a distraction. I can understand the attraction for having a monitor turn off by itself, though.
Or you could use the monitor off switch in Nirsoft's Nircmd program:
So, is there actually a way to properly turn off the monitor from a shortcut or an autohotkey script or with nircmd?
For me that didn't actually turn it off, it only put it on standby, did it do the same for you?
