Eco Sensor and Screen Brightness

Eco Sensor measures the light in your room and optimizes the brightness of the TV automatically to reduce power consumption. This causes the TV to brighten and dim automatically. If you want to turn this function off, go to Menu > System > Eco Solution > Eco Sensor

Do not block the sensor with any material. It can decrease picture brightness.
