> > If by Retina display you mean an Apple display and not resolution, then yes. Because my monitor is 5k and should be able to be handled. Really? You have a 5120x2880 monitor that macOS is messing up? I've never heard that before. Talk to LG, there's got to be something wrong with it.

I can also confirm that OSX doesn’t have a good case with external monitors, but I am no longer sure that it is possible at all. Frankly, all OSes suck at it so hard that one should just try to avoid the situation. Strangely enough the new Wayland on Linux may be the most adequate at it, though it is still far from perfect.
