That's true.  Have you noticed, though, that IBM's monochrome monitor
gets its power directly from the system unit? As soon as you turn off
the computer (and the drive signals) the monitor is turned off too.  I'm
not sure about the period immediately after power on, but I seem to
recall that the BIOS initializes the video hardware tout suite.
