These numbers refer to the rows, so the horizontal resolution.
Yes, that is the number of rows. But that makes it the vertical resolution. There’s 1080 pixels from top to bottom. If the arrows/triangles are indicating the direction of measurement, they are wrong.
I suspect that it’s an attempt at indicating a wide screen. 16:9, 16:10 etc was fairly new at the time, many buyers would be expecting their usual 4:3 screen ratio.
No, it’s definitely 1920 columns and 1080 rows.
I don’t know what the sticker is trying to say. I can read it in two ways, and one of them is kind of correct while the other is definitely wrong. And that is unnecessarily confusing, and therefore mildly infuriating.
I don’t know what you think OP is wrong about.
