I just bought a new 2019 frame TV. I was under the impression that when I would walk by the TV or when the lights were turned on that the Art mode would automatically turn on. That does not seem to be working. Is it supposed to turn on by itself or am I mistaken?
Make sure you have disabled the auto power off option in the settings. The tv treats Art Mode as being on and so powers the TV off after that time. You then need to use the remote to switch it back on. Also make sure you have the latest firmware version installed.
