Speaking of Blade Runner, back when I had an 800x600 projector, I was having a hard time not noticing the DLP squares. I had a 1080p copy of Blade Runner. I downscaled it with a strong Lanczos filter, so the video looked too sharp. Then I put the projector slightly out of focus. The DLP squares disappeared, but the blur also compensated for the sharpening and the video looked amazingly non-digital.
Basically what the low-pass filter in digital cameras does.
I think the most famous example of using this technique, that's maybe easier to remember and refer later, is the correction of the flawed mirror of the Hubble Space Telescope.
That was always stupid and there were always demonstrations of said stupidity. It’s one of those snarky contrarian takes people repeat ad nauseam. See also: correlation and causation.
