Some people have mentioned that once you use 4K, you can't go back. I guess I'm in the group that has used 4K (or 5K, in my case), and found it easy to go back. At work, we have these 5K, 27" LG monitors: https://www.apple.com/shop/product/HMUB2LL/A/lg-ultrafine-5k-display https://www.apple.com/shop/product/HMUB2LL/A/lg-ultrafine-5k... . Don't get me wrong, they're great, but... I don't feel like I'm missing anything when I go home and use my Dell U2412M (1920x1200, 24"). And working from home the past three months hasn't tempted me to upgrade my monitor, either. 1920x1200 gives me a good amount of real estate at 100% scaling, and that's the main thing I need. Now it is true that if I look at the font in this text box in Vivaldi, the rendering kind of sucks; Firefox is a bit better. There was definitely a time, around when I switched to Windows 6.x from 5.x, when I was passionate about this, and dislike for the Windows 6 font rendering was one of the reasons I stuck with XP as long as I did. Maybe 4K would help with that, but by this point I've adjusted. And even so, spending $900 on the monitor the author suggests is not the most appealing option. That's a lot of GPU upgrade you could get relative to the $300 I spent on my current monitor in 2011. Or I could double the RAM in all my personal systems and get a nice microphone (which would have more of an impact on my working from home experience). Or I could built an entire Ryzen 7 3700 desktop for that price. There are just a lot of things I'd rather prioritize. I'm also find the proposed productivity benefits dubious. As long as the fonts are acceptable enough that I don't find them actively distracting (and as mentioned, with bad enough font rendering that can be the case, so perhaps the author is simply more sensitive to that than I am), how much I can focus is going to have a lot more impact on my productivity. I do somewhat fear that this might re-ignite my former font pickiness, though...
