Standby Values

[sjml]

More a question than an issue, but can't see a better way to ask...

I know the standby settings are not documented, but curious about them.

m1ddc set standby 1 -- wakes the display up
m1ddc set standby 2 -- puts the display to sleep / suspends it
m1ddc set standby 5 -- turns the display off

However, the values of 3 and 4 seem to do the same things as 2, at least on my Dell display. From the scant documentation of DDC and the 0xD6 signal I've found, I can't tell if there's meant to be a difference between 2, 3, and 4. Any idea on this?

(I've seen reports with other tools about monitors getting bricked with inappropriate use of the DPMS stuff, which I imagine is at least part of the reason you've left this undocumented... but also the reason I want to be cautious in my own use of it. :) )
