OLED-Sleeper
Lightweight tool that dims idle monitors and wakes on input.
Many people use multi-monitor setups but occasionally want to turn off or dim secondary displays without putting the entire computer to sleep. This is useful when gaming, focusing on a single screen, or reducing distractions. It can also help protect OLED and similar panels from burn-in caused by static images. Windows power settings control all monitors together, so individual displays cannot normally be managed.
