Can you be less cryptic and on topic? Someone said he uses the DPI settings for accessibility reasons and you the expert say to use Zoom instead because you know better, can you copy paste from the article what we are doing wrong and tell us exactly what is the correct solution, maybe link to Apple(preferably not GNOME article that says DO NOT USE DPI scaling for accessibility.

I use both methods int he past and it really depends on OS features and the apps you have to use but let me know your expert opinon.
