Is there a command to power down the display in Windows XP? That is, a command that causes the video card to stop sending a signal to the monitor until input is received, much as power management does after a time.

Not as far as I know but you can use utilities like Monitor Off to power down the monitor.

There is also a utility called NirCmd, which supports not only this but more commands (like changing system volume, manipulating services etc - documented in the page linked). Usage is via the command line:
nircmd monitor off
And sometimes I've seen Windows "listening" to your last keystroke (the Return that confirms the command) after the command is "issued" and waking back up. A solution that has worked for me in most cases is:
nircmd cmdwait 1000 monitor off
Disclaimer: although this may be the third or fourth time I mention it here, I have no association to the NirCmd's team: just a happy user.

1Unfortunately it doesn't look like nircmd can be used to turn off a single monitor (in a multi monitor setup) – Sridhar Ratnakumar – 2014-05-04T02:17:58.097

Why this script is good?
Display will sleep again in 3 sec
Even if mouse by accident was moved or any program waked display up.
How-to:
Github-Gist / setup_display_timeout.cmd
Part of code:
powercfg /SETDCVALUEINDEX %current_scheme_token% SUB_VIDEO VIDEOIDLE %seconds%
powercfg /SETACVALUEINDEX %current_scheme_token% SUB_VIDEO VIDEOIDLE %seconds%
powercfg /S %current_scheme_token%

Excellent. This worked spectacularly. – Ignacio Vazquez-Abrams – 2010-04-05T17:02:39.470
