A:Answer There's no menu option if that's what your looking for. Unfortunately it's not that easy. However, there is a dramatic difference in picture between all three options if you have the correct setup. For true 4k you need the right TV, DVD player, 4k movie, AND cables. The clarity will always only be as good as your weakest link. If you don't notice a difference between 4k and Bluray, something's wrong with your setup or player. In your pic it states that the movie is only displaying in 1080p. That can be caused by either the TV, cabling, or the movie itself. In order from top to bottom it shows: Picture quality; sound; dvd player; and last HDMI cable. I'm guessing it's your cable. You need to makes sure it's a 'fast speed' HDMI cable and that its not damaged. Most cables now will have '4k ready' or 'high-speed' written on the package.
