Monitor goes into sleep mode when set to never

[stream]

All settings are set to never allow the monitor to go into sleep mode but it does. I am quite sure it is the computer that is doing it as I can move the mouse and it comes back on.I think there are settings in the bios that need to be changed, but i don't know which ones. I have an Phoenix Award bios. Any help would be appreciated. Stream.

I personally know several models of monitors have their own sleep mode. I would do this as a prank since they also had a mode where the monitors would turn off at a certain time of the day.
