High Sierra DPI Issues

Sounds like you simply need to change the size of your fonts in your browsers, windows, etc.

Alas not. If I increase fonts on a window on the external display it’ll be very large when on the internal display after disconnection.

The solution is probably for the DisplayLink driver to get the DPI right for the external display and not touch the DPI of the internal.

Hi dammad,

When you add a screen, macOS will treat the whole desktop layout as new.
This means everything will go back to defaults and you may need to re-arrange resolutions and screen arrangement. These settings will be preserved and applied again every time the same set of displays will appear (which means when you'll again connect the same external screens).

To adjust the resolution of the internal and external you can go to System Preferences->Displays.
Remember that to see all resolutions you may need to press the option key while clicking on Scaled (see https://support.displaylink.com/know...rticles/901956)

Cheers
Carlo
