Moire effects.
Modern TV sales demo videos are chosen for the exact kind of thing you start to see when the resolution gets higher. Footage of the ocean waves, schools of fish, flocks of birds.
Moire effects and screengating are way larger than any one pixel. They make ripples and lumps in the image.
You get used to the way hair looks on any generation of TV but it's nothing like "imperceptible" distortion.
You can stand dozens of feet from an 8K, a 4K, and a 1080 TV and tell the difference when the image is of many tiny objects moving across each other.
Grass. Leaves. Sand. A tiled floor viewed from an angle. You know, rare stuff like that.
- ants_a 6y agoMoiré effect is due to aliasing. If images are properly filtered (blurred) before sampling there is no moiré.
- StrictDabbler 6y agoBlurring it absolutely reduces moire at the expense of distorting detail. So now you just have another thing that's larger than a pixel (the blur area) that's reducing the effective resolution of your display, and you can't just say "the pixels are too small to be seen at this distance." There will be a point where increased resolution isn't any use. When that happens they'll stop making higher-resolution TVs because human beings won't go into the store, look at the TV from far away, and say "holy shit, that has so much more detail from this distance than I've seen before." Hasn't happened yet. We still have further to go before we hit the human visual sampling limit even for far away viewing, let alone close-up detail like reading a page of text in a scene or accurately representing a houndstooth jacket. A blurry houndstooth is not the same.
