[GuB-42]

The tables were good for the time they were picked. And the beginning of the article, it shows that at low resolutions, both ringing and banding are unacceptable. At high resolutions, beyond what was considered normal when the original quantization tables were chosen, then ringing becomes much less of a problem, so it makes sense now to change the quantization tables to prioritize banding over ringing.

It is no secret that high resolution images and low resolution images compress differently, and modern codecs are optimized for high resolutions in a way that older codecs weren't. For example going from H.261 to H.266 globally improve video compression at every step, but it is most apparent at higher resolutions.

Slightly more precise: ringing becomes much less of a problem in high resolution images when viewed on a high resolution screen (in Apple language: retina).
