Problem with lumix gx85

[Krimsonhead]

I must have inadvertently changed a setting...help.......my gx85 , with a 15mm lens, shows both on the back screen, and through the viewfinder, a cropping of the image...instead of the entire image.....ie I have about 20 per cent more subject matter on the recorded image, than I do in the preview.......how can I fix this so I have an accurate way to frame my picture?
