Unity player settings default icon
You can override this for specific platforms. Aspect Ratios selectable in the Resolution Dialog will be monitor-supported resolutions of enabled items from this list. I am currently using the following code.
Use the Player settings to set various options for the final game built by Unity. A Cichlid Aquarium with an Aquaripure Nitrate Removal Denitrator Filter. The default icon that the application will have on every platform.
