Hi! I just got my new 55'' The Frame and I can't figure this out: When the TV is in Art mode it is supposed to adapt to the brightness in the room, right? In the evening or when I turn off the lights in the room, there is no change in brightness of the picture in Art mode. So at evening it glows like a flashlight and doesn't look like a true picture at all. I've seen the TV in other homes not behaving like this, so I don't understand what is wrong with mine. Can I do something with the settings to fix this or is the light sensor defect? Has anyone experienced the same?
