  Regardless of the above, the monitor does not blank after 10 minutes
(i.e. 600 seconds).  If I run "xset dpms force off" from xterm (both as
local user and as root), the display goes dark... for approximately 1
second... and then returns to normal.  Don't know if this is relavant,
but yesterday I was fighting a grocery delivery website for the better
part of an hour trying to place a simple order.  In the course of that,
X crashed to a text tty commandline a few times.

  Calling support confirmed a nationwide problem at their end.  The help
desk guy was surprised that I managed to get my order through at all; it
was that bad at their end.  Anyhow, my order was delivered OK this
morning.  The DPMS issue started yesterday, so I wonder if it's related
to the X crashes.

  So I turned the monitor off with the physical switch, took a nap, and
turned it on when I got up.  Now the blanking works again.  Cue the
Microsoft support jokes.  What gives???

Are you using a Display Port, or HDMI connection perhaps?  Modern monitors 
come with their own onboard chipset which may lose sync with the PC.  I've 
experience the opposite with mine when I first bought it and thought the PC 
had crashed ... :-)

At least you have a power switch.  (something about uphill both ways?)  
I recently bought a pair of reconditioned 27" Acer 2K monitors, and they 
do not have a physical power switch.  I have also not found an "off" in 
the on-screen controls.  They do go blank for power saving, but they 
take about three seconds to wake up again.

  HDMI port according to the message on the display.  Another quirk
when the blanking works and the screen is dark.  Every several minutes
the entire screen goes bright blue for a few seconds and then returns to
dark for the next several minutes.

I haven't been following this thread as I'm not familiar with xset but
this info made me think.  Could you have a bad cable?  Maybe the plug on
the back of the monitor or video card is worn out and not making a good
connection?  Maybe there is a dust bunny in the connector preventing a
good connection. 

Just a thought.  Maybe.
