Both get referred to as 2K. https://en.wikipedia.org/wiki/2K_resolution

No, 1080p is 2K because its width is 1920 (close to 2000), 2160p is 4K (3840 px wide), 4320p is 8K (7680 px wide). It’s not 1K, 4K and 16K.

The town name and state is also very easy to figure out, and you can easily verify it by checking where Musk will be holding a town hall today. For each of the most violently crossed-out words, D███ and C███████, there is just one first name matching whatever is visible. Yes, I copied and pasted letters from elsewhere and the width is correct.

Greedy marketers just wanted to show a higher number… That’s why they switched from height to width, too.

By having seen a low-end 2017 laptop?

1080 rows of 1920 pixels each
1920 columns of 1080 pixels each

If 2K referred to the number of pixels, it would look like this:

FullHD is actually a little over 2M pixels.

The terms “2K” and “4K” were totally commonplace since about 2010, although not as prevalent as 1080p. I hate how the video industry switched to marketing horizontal resolution (and rounding it up) just to make the number look big.

I know the difference but there are lots of people who aren’t really savvy with video technology. I wouldn’t blame them for thinking that ［🢐 １０８０ 🢒］ is just barely better than 1024x768.

2k and 4k does not refer to horizontal resolution but the number of pixels

Nope. 1080x1920 is 2 073 600 pixels, which would be 2M. “2K” is 1920 rounded up.
