(My question is essentially similar to this: How can I set a custom screen resolution for my Android TV box?)
Does Android TV allow the user to set the output aspect ratio?
(I'm planning to add streaming video to our family living room, but I'm not allowed to replace the late 80s-early 90s analog TV, so I need to use a HDMI to composite converter. That forces the output to 4:3 even if the input is widescreen which makes the picture stretched/distorted.
I understand that in the linked question it was answered and it was only possible via adb. Does that still hold or did later versions of ATV OS add this feature via the UI?)
