Monitor(s!) won't wake from G4 sleep

[tokyotripper]

I have been having this problem for a while so I thought a clean install with Tiger would help but it hasn't. Whenever I set the machine to sleep it nips right off but no longer sends a signal to the monitor to sleep and or wake! It used to be that the monitor would fall right asleep next to my G4 but no longer. I switched monitors with my wife who has never had a similar problem with her G4, and the same thing keeps happening!

Brand new clean install of Tiger just 2 days ago, and still the same problem as before. Haven't found a thing searching the forums, anyone have any idea? Thank you!

I know that my flatscreens at work are dual channel (digital and analogue). If the screen looses the signal, it searches both inputs and then wedges onto the analogue feed, though the outside screen is digital. I have to manually switch it then.

Perhaps resetting the monitor’s preferences will help.

Also, perhaps have your computer redetect the monitor(s).
Sys Prefs --> Displays --> Detect Displays

Does it need drivers? Does it need something to launch during startup?
