5. Why won’t OBS capture a game in full screen?

OBS may fail to capture the full screen if the wrong capture mode is used. Some games need OBS to run as an administrator, or they may block capture settings. Using borderless window mode can help. Borderless mode is more stable for OBS than using a full screen.

6. What does Ctrl+Z do in OBS?

Ctrl+Z in OBS works as an undo command. It reverses your last action, like moving a source or changing a setting. However, it doesn’t undo everything, such as deleted scenes, after saving. Ctrl+Z saves time when adjusting layouts during setup, so it’s better than manual undo.
