If your LG TV dims automatically, we recognize that this might be a source of anxiety. In most situations, this is a feature of the television rather than a damaged screen.
Typically, the screen dims during scene changes, as the image transitions from light to dark. What happens is that the panel processor reduces power to the backlight in settings where there is more darkness than light.

Fortunately, we have a few ideas and strategies to stop the screen from dimming automatically by altering the screen settings.

Why does my LG TV dim automatically?

Your TV will decrease on its own due to a feature called Ambient Light Detection, which monitors the amount of light in the room and adjusts the brightness accordingly. In a dark environment, the screen will get darker, and in a light room, it will become brighter.

How to stop my LG TV from dimming automatically?

You might try modifying the energy settings on your LG TV to prevent it from dimming automatically.

  1. Navigate to the photo menu, then select settings > advanced > picture.
  2. Select the Energy Saving tab.
  3. Turn off the Energy Saving feature.

If it doesn’t work, try turning off the’smart picture mode’ and instead utilizing the ‘expert mode’. You may also try turning off the dynamic contract, super-resolution, and color filter.

What to do if your LG TV is still not working

If none of the previous approaches worked, it might indicate that you have a more significant problem with your television.
We’ve also heard that on certain LG models, this energy-saving feature cannot be turned off, so you’ll have to deal with it.
