Hi everyone, I’m currently developing a project in a vertical aspect ratio of 1080x1920p. I’ve setted the resolution from Widget Canvas and DPI to this resolution, then if a play (as a standalone or by building my project) in Windowed or WindowedFullScreen everything works fine and preserves the aspect ratio, but when entering the FullScreenMode the camera is like it moves to the right cutting it in half and the lower middle screen is black (the UI elements just don’t show).
If I understood your issue correctly, here are two common solutions that usually help in these cases, along with a reference post that might guide you toward a fix.
First, make sure that the Anchors of your UI Widgets are properly set to stretch from edge to edge of the screen. This is essential for the UI to adapt correctly when the resolution or screen mode changes.
Second, if you are using a Scale Box, double-check that it is configured correctly to preserve the content’s aspect ratio. This should help prevent stretching, cropping, or black areas when the viewport switches to fullscreen.
In the following post, a solution to a very similar issue is discussed, and it shows step by step how to properly configure both Anchors and the Scale Box to avoid these kinds of problems:
Lastly, I’m sharing a video that shows how to properly configure the different screen scaling options and set them up correctly for various resolutions. Display Options Full Screen Mode
