Larian Studios Forums Baldur's Gate III Baldur's Gate III - Technical & Gameplay Problems Screen resolution change not getting stored

I have a 4k monitor and windows is set to display at 3840x2160.
When BG3 is started the resolution is set to the same (borderless winwow) and I have to manually change it to 2560x1440 as my PC is not really fit to play games in 4k.
This change is not stored and I have to change it again on every login.

Strange thing: I checked graphicSettings.lsx (located in C:\Users\<your name>\Documents\Larian Studios\Baldur's Gate 3\) and the manually changed resolution is stored there after I close the game but it does not restart at 2560x1440.

When I start with DirectX11 the Screen Resolution is set to the resolutiuon set in Windows (3840x2160) regardless of the resolution I had manually set in the options before. However when I start the game in Vulcan Mode the resolution lastly set in the Options is used.

I had to do this to get my 1440p settings back. I don't know where Larian has them getting the Aspect Ratio screen resolutions, but my Baldur's gate still don't properly pull up the whole list of Aspect Ratios with their sublist of resolutions. 16:9 just has 720p, 1080p and 2160p. Somehow I have a 256:135 aspect ratio, but no 3:4 or 16:10 listed.

I wonder where those are supposed to be stored for retrieval.
