Not exactly related, but I’ve been using macOS, Windows, and (for the last week) Linux all on the same LG HiDPI screen (4K, but small screen), and no matter how I try to wrangle Windows I just can’t get it to look good. It’s incredibly frustrating when you know how good the monitor
can look.
Linux seems better somehow but I haven’t had as much time with it there, so I’m not exactly sure why.
