@ultravision3d The automatic config creator doesn't appear to create the param window_monitor: 0

Adding it under: window_position: UR window_monitor: 0

Fixed the issue for me

running manim-render example_scenes.py OpeningManimExample instead of manimgl example_scenes.py OpeningManimExample worked for me. Afterwards I had no problem running the original command

I have the same issue. Tried both fixes mentioned above and the problem persists. Any advise?

This is due to a bug in screeninfo. This pull request has solved it for me.

I tried the pr in screeninfo. Unfortunately, it didn't work for me. Any advice?

It can be fixed manually by just replacing all the monitor variables in window.py and config.py. You can set them to a constant like monitor.width=1920.
