The following image is a screenshot taken by the help of Windows 11 and taken from my own computer. The following screenshot offers an explanation about how to adjust the screen resolution if a video game is installed through Steam and was developed by the Unity game engine. The resolution commands given above may only work if the Unity game launcher does not override these settings. Keep in mind that ultra-wide resolutions are prone to having visual issues and the menu might become not accessible. If the game is unable to close, cannot exit out of the game, press ALT+F4 or try other key methods to exit out of the game. To minimize the game, press ALT+TAB."
