alt Hacker NewsWait, I do my work on a 4K display, according to a calculator I have a PPI of 150, but I already find my 4K display completely overkill!
Now, I spent an amount of my work life staring at a company-issued 27 inch 1080p display, and that was absolutely horrible, but with 4K, I'm not sure if I would even be able to see the improvement if I went to 6K or 8K even, which I always thought was mostly useless outside of gigantic television sets. Is it really worth it? Can you really genuinely see the text blurring on a 4K monitor?

I would probably see text quality issues on that setup. It depends on how far away the monitor is. PPI on phone screens tends to be much higher than PPI on laptops which tends to be higher than PPI on monitors, because each is typically used at a different distance.
If you're not using text around 9 pixels tall, as in the article, you're probably going to be okay. On a 27 inch screen at a typical office screen distance, I'd probably want 6k, but 4k is pretty good and 1080p is terrible.
I went from a 27" 4k display to my 5k iMac I converted to work as an external display. You can definitely see the difference, especially with text. The 4k - although a HUGH improvement over 1080p monitors - will still have that fuzziness on fonts.
