That is, if your TV set displays 4K resolution, and you are watching HD content off a Blu-ray player or streaming device, then something in the chain is upscaling that HD image to fit the 4K pixels of your TV. I would like to hear people's thoughts about what device in the chain they use to upconvert HD to 4K.

Of the movies actually shot and mastered in 4K or higher resolution (e.g., Blade Runner 2049, The Revenant, 1917), and putting aside older films shot on film, 1917 is one title I have where comparing the 4K disc against the HD Blu-ray disc, the details, colors, blacks and contrast of the 4K UHD format add a really amazing sense of fine detail, three-dimensional depth and pop that the HD format doesn't have. But I will break his rule and note that 1917 is the one 4K title I have that makes me go, "That's what 4K is all about!" Many 4K titles are actually upscaled from a 2K digital intermediate master (especially movies heavy on digital effects). The OP said he is not looking for a feature film or motion picture. (After that, I'd show whatever 4K nature/travel videos seem interesting to them off YouTube.) Of my 4K discs, this is what I would put on to show off my 4K TV to a guest. They were shot almost entirely in native 4K or higher resolution, and cover all sorts of scenery and colors.

For 4K eye candy, I really like Planet Earth II and Blue Planet II.
