2K resolution is 1920 x something. Both 1920x1080 and 1920x1200 are 2K.

I thought QHD would be nice enough at that size but I really like my 3840x2400 14"-ish Dell Precision. The extra resolution means the fonts look printed instead of no-too-pixelly.

1920x1080 is 2k BTW.

TIL that the terminology changed at some point to refer to horizontal (e.g. 2K) rather than vertical resolution (e.g. 1080p). Probably ages ago.

It changed with the “K”. The marketing teams decided that 4K sounded better than 2160p. This is all the more ridiculous as 4K usually means UHD where neither axis has 4000 pixels ( 3840 x 2160 ). In the industry I am in, this would be called 8 MP ( Megapixel ) instead.

After the popularity of 4K, somebody noticed that they could start calling 1080p 2K to make it sound better than 1080p. If you say 3 MP, does that sound even better? I mean, 3,000,000 is more then 2000 right?

it never changed, p in 1080p always referred to progressive lines as it came from movies/tv, 4k always meant 4096 at horizontal. We still have 2160p which is 3840×2160 They never replaced each other, just different definitions for screen sizes
