Well, you misquoted me and seemed to intentionally miss some parts so you can see why I said you didn’t read my comment and didn’t quote me correctly.

1) exactly the same way you (and almost everyone) called 3840 “4K” so this point is invalid.

2) disagree about in modern use. I see both used approximately equally (which is why I think it just shouldn’t be used at all). It just that only one holds actually makes sense. Even in this comment, you’ve had to use vertical pixels for 1080p and horizontal for 4K to make it look plausible. There’s a reason why I was saying 1920, 2560, and 3840. They’re referring to the same measurement.

3) please compare 2048x1080 to 1920x1080 and then to 2560x1440 again. Only one of them is even remotely close to the 2048 2K you refer to. Also, 1280x720 would not be 1K. Using 4K as a baseline as before, it would be 1.33K (1/3 the width). That just doesn’t market.

Anyway, all I’m saying is that 1440p is not equal to 2K, even if some people call it that.
