Hi,
If the image appears too dark, we suggest disabling certain energy-saving features, which can automatically adjust brightness and affect how the screen looks.
Go to: Settings > All Settings > General & Privacy > Power and Energy Saving, then turn off Brightness Optimization, Energy Saving Solution, Motion Lighting, and/or Contrast Enhancer.
You can also adjust the Picture Mode to better suit your environment: Settings > All Settings > Picture > Picture Mode
• Standard – Default mode for general viewing
• Dynamic – Brighter and clearer, ideal for well-lit rooms
• Movie – Best for dark room viewing
• Eco – Energy-saving mode
• Filmmaker Mode – Preserves content as intended by creators
To fine-tune brightness, go to: Home > left directional key > Settings > All Settings > Picture > Expert Settings, then adjust the Brightness level (0–50) to your preference.
Lastly, please make sure your TV is running the latest firmware: Home > Home > left directional key > Settings > Support > Software Update > Update Now
We hope these tips help improve your viewing experience. If you need further support, feel free to contact us at 1-800-SAMSUNG, 8AM – 12AM EST, 7 days a week. LiveChat is also available via the ‘Support’ link on our website.
