Is it possible to change the size of the font of the UI for high DPI monitor?

Thanks for taking the time to provide such a detailed reply, that’s very much appreciated. I’ll take a look at this when I get some time this evening. The solution I used in UE4 was to access and modify the settings found in: Developer Tools > Widget Reflector, but I can’t find this setting in UE5. In case this makes any difference, I’m also using UE for non-games purposes too. Therefore, I haven’t used or attempted to modify any specific “game” related settings. I’ll take look and let you know if this works for me. Thanks again, much appreciated.
