If you have different layouts and want a specific one to open each time, then you must rename it to have a 1. in the name. You can also give it a name that starts with an A, and it will then be the default layout. The reason for this is that PigVision sorts the layouts in alphabetical or numerical order and then opens the first layout.
Within the layout setup, you can also tick the box on the right-hand side that is labelled “Use this layout on start-up".
