Just purchased on May 1, 2020, 43" TV Model UN43TU700DFXZA(2020 yr model). While trying to adjust picture size to fit to screen, it says function not available for Picture Size Settings 16.9 Standard. How come? Is there a way around this? Or Is this function only available on certain models? What models are those?
I'm sorry to hear that, are you trying to change the picture size while watching cable TV or using an app?
