Those same few years ago, I would use charts like this to guide friends shopping for TVs toward a comparatively inexpensive 720p Panasonic plasma, because the deep, rich blacks matter more to our perception of sharpness than pixels too small to resolve at normal seating distances. Those who followed my advice were invariably happy with their choice.

I never doubted that last year’s push of 3D televisions would fall on its face, but I do worry about consumers being tricked into thinking 4K matters, because they were with 1080p. Many friends ignored my advice to go for the crisp plasma blacks of the 720p Kuro and instead opted for a 1080p set, due to the same inability to shake the sense of more-is-always-more that drives consumers to buy increasingly high-megapixel point-and-shoot cameras.

Back when Morrison was conducting his experiments and I was pushing 720p, we were already fighting a losing battle. No one wanted 720p TVs, even if their viewing experience would be better with them. 1080p became a buzzword, a must-have—charts and math be damned. Now you needn’t even check if a TV is 1080p “full HD”—they pretty much all are, because that’s all that would sell.

And today, that’s not such a bad thing, because the contrast levels of 1080p sets are now quite good. There are worse things about modern TVs than their excessive pixel counts.
