What to do if the resolution when building the game is incorrect?

Question

Screen resolution

When building the game, the screen resolution is incorrect.
In the game, everything is fine, but with the build, the resolution of the game narrows.
I tried to set 16:9, 1204:720, 1820:1280 and in each of these cases the screen resolution after the build is the same.
In Player Settings / Player / Resolution and Presentation, I tried to set Default is Native Resoulition to the right one, it didn’t help.
