Like many televisions, the LG Smart TV eats up quite a bit of energy when running normally. Luckily, the TV allows you to enable energy saving mode to reduce the amount of power that you use while watching. This tutorial will show you how to do so.
How To Enable Energy Saving Mode on LG Smart TV
Press the Home button on your remote control, and select the cog icon (top-right corner) to access Settings.
Head to Picture > Energy Saving.
From here, you can choose for your TV to auto-adjust screen brightness according to ambient light or select between Medium or Maximum energy saving intensity. At its highest level, the TV's energy saving mode lets you turn off the screen while maintaining audio playback.
