How build Windows standalone in 16:9 widescreen

Hi anyone knows how to build a game in widescreen? The default ratio is 4:3, how can I change it to 16:9?

Thank you

In the Unity editor, go to `Edit > Project Settings > Player`.

In the Inspector, click the little Finder/Windows icon under Per-Platform Settings, and expand Resolution and Presentation.

Inside, you can change the default screen width and height to a 16:9 ratio, and expand Supported Aspect Ratios to un-check 4:3, 5:4, 16:10, and Others.

Just changing the supported aspect ratio to 16:9 won't force a game to use widescreen if no widescreen resolutions are available. (The desktop resolution can always be selected no matter what.) If you want to force 16:9, use AspectRatioEnforcer.
