BUDS2 definitely has a learning curve compared to the original. The included manual will help you get a better understanding of its usage. As to the aspect ratio, that is dependent on your computer and Windows version. The best suggestion I can offer is to make sure that your computer is running in the recommended setting by Windows. I use an HP laptop running Windows 11 with the screen resolution set to 3840x2160. This is a 15" 4k screen. Your setup could be completely different.
