In the power control panel, set the monitor off time period you like.
My son's computer (Winfast ncr18 MoBo, 160GB WD Caviar HDD, 512MB RAM, XP Home SP2) usually doesn't respond to mouse/keystrokes after the screensaver comes on (you're hosed). A workaround is to turn it off, but I'm trying to avoid wear and tear on the monitor (it happens on various monitors). Are there CMOS tweaks I can use to blank the screen? The setup settings are:
ACPI Function - Enabled
ACPI Suspend Type - S1(POS)
Power Management - User Defined
Video off method - DPMS Support
Harddisk drive power down - Disabled
Harddisk drive power down in Suspend mode - Disabled
