Hello, it's not specific to a type of video, but just a problem when you go fullscreen in Netflix, Disney+, YouTube, etc.

I watched Modern Family on Disney +, made it smaller

Try this vid on YT : https://www.youtube.com/watch?v=6Ck1d6qo8a0

Also, this is specific to Macbook Air M2 screen

That video is 1920x1080. On a 2560x1664 display, we'd expect black bars at the top and bottom, but not on the sides.

If you load https://davidwalsh.name/demo/fullscreen.php and click "Launch Fullscreen", then are there any black bars?

Yes, the top line is blanked out which is fine, but the two sides are removed.
