In old Unity versions a feature known as Resolution Dialogue/ Screen Selelector would automatically come up and let the user remap their input options for both keyboards and controllers.
Alongside this was the ability for switching between "Basic, Better and Best" graphics settings, with "Basic" being the old mobile shadows and shaders and "Best" being the modern PC ones, plus the ability to set whether the game is fullscreen or not upon boot and your screen resolution of choice.
As of Unity 2019.3 this feature was fully deprecated and can no longer be accessed, making these older options inacessible by the player.
