I am unable to get my monitors to go to sleep automatically. I have tried removing and re-installing GPU / chipset drivers. I rebooted the machine between each step. If I set the power button to sleep the monitors they will go to sleep when you hit the power button.
I cannot find any errors in event viewer on why they will not go to sleep. I have tried setting time out to 1minute all the way up to 1 hour. I will go to sleep for the night and monitors will still be on in the morning. Windows and all drivers are fully up to date.
