I think it is because of the size of the screen you are reading on. I have a really bad and small phone that I use to take screenshots, so it might look blurry if you scale up the pictures.
When it gets to the point where the words can't be read it's not about screen size. Or maybe in my phone it is even blurrier, it might happen if the image is too big.
thank you I was just Curious
Oh ok thx
Is it just my computer because the words are really blurry
