Hi all -- As the title says, I recently got a samsung 4K Frame TV (QN65LS03TAF). However, whenever I place it into art mode, half of the screen seems dim, like a shadow is over it. I assume it is because the ambient light sensor is picking up the light from the windows that are to one side. I am wondering how I can fix this, or turn off the sensor so that it isn't as obvious when in art mode. Thanks!
