I use linux at home (with a HiDPI screen) and MacOS for work. The screen works well with both computers. I mostly just use a text editor, a browser, and a terminal though.
Linux has bugs, bug MacOS does too. I feel like for a dev like me, the linux setup is more comfortable.
Same here. I stick to 100% scaling and side step the whole hi dpi issue. I even have a single USB type c cable that connects my laptop to the laptop stand and that laptop stand is what connects to the monitor, keyboard, and mouse.
I know people will say meh but coming from the world of hurt with drivers and windows based soft modems — I was on dial up even as late as 2005! — I think the idea that everything works plug and play is amazing.
Compare with my experience on Windows — maybe I did something wrong, I don't know but the external monitor didn't work over HDMI when I installed windows without s network connection and maybe it was a coincidence but it didn't work until I connected to the Internet.
