UHD is 4x Full HD resolution. The person who wrote that can’t even do math. That’s like saying 4^2 = 2 x 1^2 because 2 x 1 x 1 = 2 x 2
Comment on 4k is not 2160p - heard it here first!
Strangle@lemmy.world 10 months agoIt’s pretty confusing
“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”

It’s obviously talking about horizontal lines, not pixels

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:
SaltySalamander@kbin.social 10 months ago
Heh, no. 4k is exactly four times the resolution of 1080p.
WestwardWinds@lemmy.world 10 months ago
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.
ricdeh@lemmy.world 10 months ago
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.

1920 x 2 = 3840 (4K UHD)
That’s what he’s talking about.
newthrowaway20@lemmy.world 10 months ago
Yeah but that would only be an increase in the horizontal resolution… you’d have 3840 x 1080.
So you gotta double the verticall resolution too, which means you’ve now doubled both horizontal and vertical resolutions, which is equal to 4 times the initial resolution
