<snip>I never did find a way to put it to sleep, using the DVI interface on the X300, using either SNAP, or Panorama (I am using SNAP on the new system - I haven't tried Panorama, yet).

......It is best to tell the system what monitor is attached, so that it also knows what the monitor is capable of doing. If you attempt to do the settings yourself, you can get it into a setting that the monitor doesn't know about, and then you will have to try to get it working again, without being able to see what you are doing.It seems to me, that in djcaetano case the 'system' thinks it knows what the monitor is able to handle, but the 'system' is not correct in his case. If it's a fault in the stored data into the monitor or a bug in snap, or a weird combination of switching between DVI and analog or a kvm between...., who knows.
On the other hand if I set the values by my own, I know that I'm correct (after a quick look into the monitors manual). The 'system' will never change settings even if I change monitors, kvms or when power or signal cord falls out from the monitor or when replacing the monitor when it breaks up. Sure it helps if you have an old CRT or a vnc connection as a last resort if something goes wrong

Of course it's kind of personal attitude to let some 'system' set things up by there own (and get lost if it fails) or to set things up to personal preference.
On thing I want to add - sometimes it makes a difference if there is a monitor connected to the DVI or Analog out at power up. It seems that the graphic chip (X300 in my case) remebers on which output a monitor was attached at power up. Primary and secondary out assignment changes with that. No clue if this matters too on other chips as the X300.
