[edit | edit source]

There's no need to unplug these displays at night, they use very little power. Abrupt power offs can corrupt memory cards on their controllers. When this happens reviving them may involve time-consuming re-flashing. Some displays may have an on/off button.

Many LED displays are setup to go to sleep between the hours of midnight and 8am to save a little power and calm the space.
