“UHD features a 16:9 aspect ratio and is twice the resolution of full HD. In other words, two times 1080p, two times 1920 x 1080 pixels, that is 3840 x 2160 pixels. Having the same 16:9 aspect ratio means it is backward compatible with other HD derivates. However, both 4K and UHD can be shortened to 2160p to match the HD standard and therefore, companies use the terms interchangeably.”
“If you think 4K and UHD are one and the same, I don’t blame you. I blame the companies that LOVE to use them interchangeably all the time. You pick up a Blu-Ray movie disc of a 4K movie and you will most definitely see an Ultra HD label on it. 4K is actually not a consumer display and broadcast standard but UHD is. 4K displays are used in professional production and digital cinemas and feature 4096 x 2160 pixels”
Actually, display resolution refers to exactly what you call pixel density, and NOT the pixel dimensions. This error is so common that the term resolution has practically been redefined outside of the professional (science and engineering) space, but technically, display resolution and pixel density are the same thing.

It’s pretty confusing

I don’t know that it’s THAT confusing, since by definition we’re talking consumer grade products, not professional grade.
Amd that’s a distinction consumers have been making for years.

I mean, yeah, technically it’s classified as a pickup truck… but nobody will ever confuse it for:

UHD is 4x Full HD resolution. The person who wrote that can’t even do math. That’s like saying 4m^2 = 2 x 1m^2 because 2 x 1 x 1 = 2 x 2
Heh, no. 4k is exactly four times the resolution of 1080p.
It is double the resolution, because resolution is expressed as an x,y pair. It is 4 times the pixel density for the same screen size.
