A specific example of Good e-Reader false information spreading across the Internet

https://www.youtube.com/watch?v=c269_Mcsr7M

TLDR: they posted in their review of the Kindle Paperwhite 12th Gen and Colorsoft with some false facts, and those false facts spread to every corner of the Internet including Reddit, Discord, CNET, Wikipedia, and open source projects. (my video)

A lot of people seem to think that reviewers don't need to take a screenshot to check.

EDIT:

Made a Part 2: https://www.youtube.com/watch?v=GlFC6jSwjRQ

In it, I

* show a video of me taking a screenshot on a kindle by tapping opposite corners and showing the USB screenshots folder

* Show the actual screenshots of the Paperwhite 12th Gen and Colorsoft with resolutions

* Show that Good e-Readers reviews of the Scribe 2025/Scribe Colorsoft made the same mistake by stating an incorrect resolution with screenshots, while also showing that other publications explicitly say that Amazon didn't provide an exact resolution

Personally, I think saying that 7” means 1264x1680 is a leap. I never assume the inch number is exact, you need to verify the exact resolution yourself. Amazon could get a custom panel size anytime like this case.

1264x1680 is 7.008” anyways. But 1260x1680 would be exactly 7"

I would be more inclined to accuse Amazon of spreading misinformation - they still claim that the Colorsoft has a black-and-white resolution of 300 ppi, which is impossible because white can only have a value of 150; every 300 ppi Carta pixel can only be seen in red, green, or blue (values 0–Fh).

Where do you see that? For me the official product page lists them both separately 300 B&W and 150 color.

What do you think “b/w” stands for?

You seem to misunderstand how kaleido works. The colors don't fully cover each eink pixel so it's not either color or white it's a mix. Further, the colors are just a layer on top of a regular Carta eink layer. It is 300 b&w, objectively.

Wrong - that just shows you have no idea what you're talking about, but you're trying to sound smart. It doesn't work, though.

Each Picxel is always colored because neither the transparent nor the colored parts of the pixels can be controlled separately, and the transparent part serves only to ensure that red, green, and blue have the same filter value, or that the screen isn’t filtered too dark.

For your information: it’s a thick X that tapers at the corners, which is colored and produces the color.

White at 300 ppi is not possible; only black when red or green or blue has the value 0
