Unable to change resolution in Fullscreen mode

Technical Support

Hi, I cannot change the resolution, 4K is always used, even if I select a lower resolution in the Diablo settings. In windowed mode, resolution can be changed normally.
I found out that it is always using the resolution of my Windows desktop in Diablo Immortal’s fullscreen mode.

I am always using latest versions of all my programs and drivers.

I just checked and I seem to be having the same results, it looks like its being changed but there is no visual difference.
