4k is literally a resolution, usually 3840x2160 or something around that. 1080p is another resolution, usually 1920x1080. These are never comparable.

You would be right if lossy compression wasn’t a thing. But it is, and it’s getting used a lot.

“4k” can very much be worse than 1080p if it’s compressed in a way that erases more details. That’s what people are complaining about with streaming services and YouTube - the resolution numbers don’t mean shit, and quality at a given “resolution” has been degraded more and more over time.

They are afaik not allowed to exist with USB C. And except for some very few very sketchy manufacturers, it’s also luckily not a thing in practice.

All it ever was intended for was to make us feel like something was being done while doing absolutely nothing.

It certainly does help a little bit. But it’s of course still not a coincidence that companies are pushing for it instead of more effective measures… It’s not just cheap but it also pushes people to believe that measures to save the environment are all useless and annoying, and makes them less likely to want more to happen.

It’s still the case, at least for Firefox on Android
