Hi there!
You can change the dimming feature of your DU7200 TV by adjusting some of the energy efficiency features designed to reduce power consumption. The Eco sensor automatically adjusts the brightness level of the TV according to the ambient light level. If the Eco Sensor has adjusted the screen’s brightness level, you can select Min. Backlight to manually adjust the minimum screen brightness. You can also disable these features for a steady brightness setting.
You can adjust Brightness Optimization, Brightness Reduction, Motion Lighting, or Contrast Enhancer by going to Settings > All Settings> General > Power and Energy Saving > and adjusting the Brightness Optimization, Brightness Reduction, and Motion Lighting.
You can also go to Settings > All Settings> Picture > Expert Settings > Contrast Enhancer to manually adjust contrast.
