How to actually play 4K !
Lets Start…
I learned this from browsing discussions: If your monitor/screen resolution isn’t supported, try this: Copy & paste this line:
-window-mode exclusive -screen-width 3840 -screen-height 2160
into your game launch properties (right click on the steam game > “properties” > “set launch options”).
Thanks to the user KayJay for figuring this out! Basically, replace the 2 numbers with your screen width and height, an you’re all set! If you go into “other” it will revert, but alt+enter-ing in the main menu fixes it again.
