Well, that's the point. There are no camera settings. To view a raw file properly on your computer, you need a converter that can apply the appropriate corrections.
There is free software available from Sony:

or you can use third-party applications like Capture One or Lightroom.
But you did not answer the question why you are shooting raw in the first place.
