Same goes for calling it 4K or UHD, even when one is technically incorrect.
Why not? 4k isn’t a formal standard. It just means you have approximatly 4k horizontal pixels.
Comment on 4k is not 2160p - heard it here first!
domi@lemmy.secnd.me 10 months agoIt’s nitpicking, whether it runs at 3840x2160 or 4096x2160 does not matter. Same goes for calling it 4K or UHD, even when one is technically incorrect.
If even Sony calls their 3840x2160 blu-rays “4K UHD” I’m fine with the average person using them interchangeable.

Calling 3840x2160 "4k" makes sense since 3840 is so close.
On a different note sometimes I've heard people call 2560x1440 for "2k" but neither 2560 nor 1440p are close to 2k so that makes little sense to memagic_lobster_party@kbin.social 10 months ago
1920x1080p is closer to 2K if anything.

yep Full HD is a 2K resolution https://en.wikipedia.org/wiki/2K_resolution
Lojcs@lemm.ee 10 months ago
I think people call 1440p 2k because they know 4k exists and associate 1080p with 1k.
domi@lemmy.secnd.me 10 months ago
The logic of some people goes that anything under 4000 horizontal pixels is not “real” 4k. But as mentioned, I don’t care and also call 3840x2160 “4k” simply because it’s shorter than “2160p”.

4K is definitely a formal standard
theKalash@feddit.ch 10 months ago
Ok, can you formally define it or link me to it?
And I don’t want a definition for “4k DCI” or “4k UHD” … just a formally accepted definition of “4k” (in the context of a display resolution). We can all agree that it colloquially means the number 4000, I hope.
jtmetcalfe@lemmy.sdf.org 10 months ago
There is not one definition, if you hear “4K” you can use the context of the conversation to determine if they’re talking about the consumer 4K UHD format or cinematic 4K, neither of which have a vertical resolution of exactly 4000px. UHD standards are maintained by ITU DCI standards were developed by the DCI group and are now maintained by SMPTE

Huh TIL
I thought it was because 4k has 4x the pixel count of 1080p
jtmetcalfe@lemmy.sdf.org 10 months ago
4K UHD (along with 8K UHD and 16K UHD) are the consumer format standards for 3840x2160 image formats which includes Blu-ray. Full 4K or True 4K or DCI 4K is the cinematic 4K standard shown at 4096x2160, which many TVs supper via slight letterboxing
billwashere@lemmy.world 10 months ago
I had to go digging but 3840x2160 is both 2160p AND 4k UHD. 4096x2160 is something called 4K DCI which is more of a camera or film industry thing and is rarely used for things like TVs or video games.
domi@lemmy.secnd.me 10 months ago
Correct, but both can be called 2160p just because of their vertical resolution. Overall both terms don’t matter in gaming because aspect ratio can be changed on the fly (on PC) depending on the output device. Haven’t touched a console in years but I assume they are stuck with a 16:9 aspect ratio no matter what they are playing on?
