Controlling screensaver/power setttings

I am looking for a way to programatically control the power settings (turn display off specifically). The reason is I have photo screensaver that I sometimes want on (like if I am in the room). Other times, I just want the PC to shut off the monitor.

My question is is there a way to programatically change the power settings? I was thinking a batchfile or some shortcut or something. I know I can invoke the screensaver without waiting for it to kick in by executing the .SCR file, but I also want to shut off the display power off mode when I do so.

Thanks for the response. That didn't do exactly what I wanted, but pointed me in the right direction. I found that if I create a power scheme, I can invoke it with %windir%\system32\powercfg.exe /SETACTIVE schemename.

A simple batchfile can invoke a power scheme that doesn't put the monitor/pc to sleep and start the screensaver. Another batchfile will restore the computer to sleep.

SetActive actually takes a GUID, not a scheme name (you can find the guid in the registry). However, there are lots of other options that can be set individually:

-change settingvalue
-x setting value
Modifies a setting value in the current power scheme.
Usage:
powercfg–x setting value
setting
Specifies one of the following settings:
-monitor-timeout-ac minutes
-monitor-timeout-dc minutes
-disk-timeout-ac minutes
-disk-timeout-dc minutes
-standby-timeout-ac minutes
-standby-timeout-dc minutes
-hibernate-timeout-ac minutes
-hibernate-timeout-dc minutes
value
Specifies the value in minutes.
Example:
powercfg-change-monitor-timeout-ac5
This sets the monitor idle timeout value to five minutes when operating on AC power.
