Updated Info apr 8 2020
The Anniversary Edition has a F* bug where location names are not displayed when choosing a large UI in DX9 Mode. Against this a medium UI setting can be used at lower resolutions.
This is the maximum resolution where you can use a -medium- size UI.
height width
2600 anything
This way you are able to adjust screen width as you like. I got good results with a relatively crisp image at 2600×1920.
Dont forget to create a custom resolution and switch your monitor to it first before starting the game.
If anyone has a solution for “large UI” on higher resolutions in DX9 mode as mentioned above please drop me an email (blue button below).
