How it works

Daily energy = watts ÷ 1000 × hours watched. Yearly energy = daily × 365. Yearly cost = energy × rate; monthly = yearly ÷ 12. Lowering screen brightness and enabling eco/auto-dimming modes noticeably cuts a large TV’s draw.

Frequently asked questions

How many watts does a TV use?

A typical 40–55" LED uses 60–120 W. Large OLED, QLED and 8K sets can draw 150–300 W at high brightness.

Does standby cost much?

A little — most TVs use 0.5–3 W on standby. Over a year that is small, but switching off at the wall removes it entirely.

How can I lower my TV’s running cost?

Reduce backlight/brightness, turn off motion-smoothing and “vivid” modes, and enable the energy-saving picture preset.
