Oh look, another dead-end thread. This place is full of questions and no answers. I too would like to know why version 27.0.1 displays preview at 1536x864 when most other versions display at 1080p. A "fix" is making the windows display scale 100%, but then the text is tiny!
I am forced to use an old version because of severe stutter in most other versions.
I know this software is free, but crikey,,, what a massive frustration for so many. Maybe charge money for OBS and then we can have some technical support because life is too short for this BS?
