How to lower the cost of running a TV

TV power use depends mostly on screen size and brightness. A 50–55 inch LED TV typically draws about 70–100W, while large 75-inch-plus and HDR content at full brightness can exceed 200W. OLED TVs vary with what's on screen. Standby power on modern sets is under a watt. The default here assumes 5 hours of viewing a day.

  • Use the energy-saving or auto-brightness picture mode.
  • Turn off quick-start or instant-on features if you don't need them.
  • Set a sleep timer so the TV isn't left on overnight.
