I've dealt with this on Windows and Linux, and on Linux it was even worse. There I usually had to turn it off altogether. It was never an issue on Macs for me though, even before "retina" resolution was a thing. Which by the way turned out to be a genius way to solve the issue, even though people didn't realize at the time. However, I also remember that many people just didn't notice or didn't care. Completely fuzzy display and they just thought that was how it was supposed to be. In the XP era, people would just set the screen resolution lower to something like 800x600 to trade subpixel fuzziness for regular fuzziness. VGA cables and later cheap VGA-DVI adapters didn't help either. You got VGA fuzz plus subpixel fuzz, total mess. Fun fact: Just last year I sat down at a shared desk at work and noticed a slight fuzziness, and after some investigation saw there was a USB-C dock -> VGA out -> HDMI adapter horror-show going on. Nobody noticed!
