Exporting on a different resolution (Builds)

[ChumbaWambalala]

Hi,
I'm trying to build a simulation that runs on 1920x1920.
I set in player settings to run in window mode with a resolution the of 1920x1920. But unity keeps reverting back to I think a 1920x1080 in windowed mode.

How should one implement a custom resolution output properly?
I believe I'm missing something here.

Thank you.

This happened to me also, and changed again to another resolution and it got the desired one. It seems it's taking the previous one. No idea why.

I'm using render texture to being able to force a custom resolution
