Windows XP hangs up when shutting down

Hi Kelly .. I've just found (maybe) another fine shutdown gotcha (in
Win2k, but maybe it applies to WinXp too).
Moved a perfectly working Win2k system to my wife's study, plugged in an
Eizo L565 TFT instead of my ADI microscan CRT - only change. Here it ran
24/7, so shutdown was just for maintenance, but it always worked first
time.
In it's new home, shutdown was about 25% successful - otherwise hung at
a 'black' (well, dark green - backlight still on!) screen, with all
drives, LEDs , fans etc still running. Reset or power switch would bring
it up/down cleanly, so windows really had finished saving all files,
marking things clean, and exiting .. just the power wasn't off. Try 3-4
times, get lucky.
Then one night I failed to go 'attend' to it for 10-15 minutes, and
amazingly, it had shut down. It then occurred to me that 10 mins is the
timeout for the Eizo to go into 'nobody talking to me, power down' mode.
So .. I suspect the Win2k (=XP?) 'plug and play' monitor driver is
failing to convince the Eizo to go to sleep, which is then failing to
convince ACPI that everything is now snoring, and it can cut the power.
May only be a problem with dual input TFTs (the Eizo has analog, in use,
and a DVI socket, which isn't) .. heck, may only be a problem with =this
model=. However it worked dandy when she had a Win95b machine attached
to it, and even used to display 'turn me off when the computer shuts
down' message, iirc.
Guess I'll go try an L565 specific monitor driver and see if that helps.
This 'bad driver can cause shutdown problems' I never expected to extend
to a monitor driver, of all things .. but that's the only software that
changed!
