I'm not clear as to what you are asking.  My best guess:

All of your machines (save one) automatically blank the monitor/screen
after some period of inactivity.  But, the MythTV box does not.

On those that *do*, does the monitor go into blanking/shutdown mode?
(usually indicated by the monitor's power indicator blinking)  Or,
does the monitor remain active but "displays a black picture"?

[I am trying to get at whether the VESA powerdown mode is being
invoked or if a "screensaver" is actively drawing black]

I'm *guessing* most of your machines display an X session (or
an xdm(1) login) normally?  Does the MythTV box, as well?  Or
are "text consoles" (think in terms of the days of DOS) used?
