The way we sell screens by diagonal does seem like marketing got away with one.

[-] sp3ctr4l@lemmy.dbzer0.com 9 points 2 weeks ago* (last edited 2 weeks ago)

Further complicating this is that the screen is curved.

So... they'd have to take a tailors tape, from one diagonal to another, also pressing it into the screen, being careful not to damage it.

Either that or take a width heght and depth measurent and do a bit of trig.

[-] frank@sopuli.xyz 3 points 2 weeks ago

Yeah, measuring the arc of the curved width using the width and sagitta is a little tricky, too, but totally doable with trig.

The wiki main image suggests to me, a mere math casual, that you might even need one more piece of information than just s and l?

[-] marcos@lemmy.world 8 points 2 weeks ago

It's reasonable. What they got away with was labeling wide screens as a good thing.

[-] Speiser0@feddit.org 3 points 2 weeks ago

Well, it's also in inches, so nobody has a mental image of what the number means anyways.

I love that Amazon's approval process for reviews doesn't filter out ANY of this stupidity.

I read a livid one-star review once from a customer who angrily returned a wireless router because the box had wires in it.

What if words? Baby don't hurt me, don't hurt me, no more.

Thanks.
Corrected if into of in the title.

no, no, they have a point

why is a resolution primarily measured in vertical pixels, but a screen size is measured in diagonal? shouldn't it be vertical, so that it's easily comparable across resolutions and sizes?

[-] rayquetzalcoatl@lemmy.world 1 points 2 weeks ago

Are resolutions predominantly measured in vertical pixels? I thought it was horizontal? Like, 1080p is 1080 wide? I don't know anything about resolutions though so I'm likely wrong!

[-] mrgoosmoos@lemmy.ca 8 points 2 weeks ago

1080p is 1920x1080 (WxH)

1440p is 2560x1440

Then you get to 4K and whoops, we broke the naming convention

[-] rayquetzalcoatl@lemmy.world 2 points 2 weeks ago

Oh my god. Duh ๐Ÿ˜‚ I literally did the 1920x1080 thing but somehow still thought 1080 was the width ๐Ÿ˜‚ Thank you!

how is this a history meme

[-] JandroDelSol@lemmy.world 13 points 2 weeks ago

Pythagorus was a guy in the past

[-] horn_e4_beaver@discuss.tchncs.de 6 points 2 weeks ago

No, he was a sentient triangle.

[-] Lauchmelder@feddit.org 1 points 2 weeks ago

oh mb I thought he was a scientist

[-] bobo@lemmy.ml 2 points 2 weeks ago

Mathematicians are scientists that don't wear lab coats?

[-] ayyy@sh.itjust.works 1 points 2 weeks ago

Oof yea I did the thing where I upvotes without checking the community. Shame on me.

[-] Zachariah@lemmy.world 4 points 2 weeks ago

If you give Pythagoras the width and the aspect ratio, heโ€™ll be just fine.

[-] Blackout@fedia.io 2 points 2 weeks ago

Why is my Samsung 49-in curved monitor only 14 in high? It should be 49x49 duh.
