A year ago, I released a game that does only support 16/9 for a few reasons (UI needs to align with world space objects, Certain screen space overlay effects don’t work for other aspect ratios etc.).
The Player settings are set up to only allow 16/9. However, when switching my screens resolution to 4/3 or try on a 16/10 screen, the game is rendered at that aspect ratio. I believe that this worked when the game was released, there where black bars like you would expect.
This is what I set up in the player settings.
The game is built using Unity 2019.2.4, but I get the same issue when building an empty project using 2019 LTS or 2020.1.
Anything else I need to to to make this work? Did anybody else run into this issue?

Also ran into this issue… Did you manage to solve it?
It’s likely the following “issue” which has been marked as “won’t fix” because the approach they take to restrict supported aspect ratios is a very basic approach that they can’t enforce in fullscreen windowed mode.
You should be able to just send the camera’s output to a render texture with the aspect ratio that you want and then render that texture on a quad in the center of a black background.
