Then turn off the warning: all modern OLED monitors that do not force you to run it can both change when the timer fires, but also just disable the notification altogether. This is what I have done on mine, and mine as well also runs it when its off. If your monitor is a Samsung OLED panel, yours is a near identical sibling of mine.
