Troubleshooting Dark or Dim Picture - TV

Resolving Dark or Dim picture is usually just a matter of adjusting settings. It's important to remember that picture quality is subjective, it all depends on your individual preferences, and that LG TVs continue to win awards for outstanding picture quality when compared to other brands.

In short, rest assured that you chose a great TV, now let's see if we can get the settings how you want them.

Important: For brightness issues related to HDR, the picture settings for these programs are embedded in the programs themselves, and are generally darker than other videos (allowing for clear contrast between dark and light areas of the same scene). Due to the nature of HDR, these settings cannot be overridden.

Important: For brightness issues related to OLED, these TVs use a different form of backlight than traditional LED/LCD TVs, and cannot reach the same level of brightness. However, you can adjust the picture settings to increase Backlight and Brightness to help. Visit the Adjust Picture Settings section below for instructions.

  1. First, try to adjust the Energy Saving setting.

    1. Go to the Picture menu (Settings > Advanced > Picture).

    2. Select the Energy Saving option.

    3. Set Energy Saving to Off.

    Note: Turning off energy saving will cause the TV to consume more power.

    Is the picture bright enough with energy saving set to off?

    Yes No
  2. Ok, try changing the Picture Mode.

    1. Press the Back button on your remote, and return to the Picture menu.

    2. Select the Picture Mode Settings option.

    3. Select Vivid for the highest brightness.

    Is the picture bright enough on the vivid picture mode?

    Yes No
  3. Great! Enjoy your TV.

  4. Ok, try to reset all AV Settings.

    1. Press the Mute button on your remote three times quickly.

    2. Select the AV Reset option.

    3. Follow the on-screen prompts.

    Is the picture bright enough after performing the AV reset?

    Yes No
  5. Great! Enjoy your TV.

  6. The last item to check is the lighting in the room where the TV is.

    If you close all blinds/curtains, is the picture bright enough?

    Yes No
  7. Great! Enjoy your TV.

  8. I'm sorry we were not able to resolve your issue here. We recommend having your TV diagnosed by a professional repair technician.

    Before requesting repair service, try to factory reset the TV. This will help determine if the issue is with software or hardware.

    1. Access the General menu (Settings > General).

    2. Locate and click the Reset to Initial Settings option.

    3. Follow the prompts to reset, then re-setup the TV.

    Note: You will be prompted for the TV's password. If you have not setup a password, the default will either be 0,0,0,0 or 1,2,3,4.


    Get started online quickly and easily using our Request a Repair feature.

  9. We combat and improve glare and external light issues year after year.

    All TVs include some level of anti-glare, but we haven't found a way to completely negate it yet.

    I'm sorry for the inconvenience, but your best course of action is to keep the curtains closed if watching during bright times of the day.
