I actually am using it, but I didn't want to go down the rabbithole of an all-encompassing article on displays, PPI, scaling, etc. Using it to scale the display really helps, but I find that for the size of things I like 3008x1692 (on a native 3840x2160 panel) and this looks fine on an LCD. And is better than native res on the OLED, but still not great. It still bugged my eyes.

I just went with native res for demoing things because it's a worst-case, but the fringing problem, because it affects all strong-contrast edges not just text. It was also really noticeable at thin/narrow lines such as when doing CAD or between cells in spreadsheets.
