Resolution at build

Hi, I made a game for Windows that is 1080x1920, like a vertical mobile phone and I changed default resolution to 1080x1920 but when I build there is in in another resolution and in the resolutions chart it isnt what I want. How can I put this resolution?

Ok, I now know that it is because my game is vertical but in the resolutions chart there are only horizontal resolutions. How can I put horizontal resolutions?

*vertical
