Setting resolution for windowed fullscreen

I am currently working on our games settings and changing resolution just does not seem to work correctly.

I am trying to use windowed fullscreen, because regular fullscreen was causing crashes when alt tabing, but no matter what resolution i put, it is always at 1920*1080. Tried using the command r.SetRes 1600x900wf directly in console and also the blueprint nodes for Set Screen resolution and Set Fullscreen mode.

I haven’t tested this in forever. But you needed to apply settings 2 times in blueprint.

How are you currently applying the changes?

After setting resolution and fullscreen mode i call apply settings. It works when i select windowed and sets the correct resolution there, problem is only with the windowed fullscreen.

I have the exact same issue. In fullscreen mode, all resolutions can be freely set, and everything works as it should. In windowed mode as well. However, windowed fullscreen always sets the native resolution of the monitor and there is no way to change it. Does anyone have a solution?
