VR image quality

Hi. I m new to unity, i only have Ideas for now and i m in a learning process via docs on here and tuts in youtube. I have a basic question about Quality. In many games i see awesome trees and real-like buildings and realistic terrain objects. I have set a basic scene with a terrain and some trees only. And when i put my Gear VR on ; the view is so pixelized. What i miss? I m not a thousands dolar studio and employees owner. I m just Me.. so thats why its like this?. why all games and scenes have perfect smoothness and quality objects but my basic scene is like minecraft quality? What i miss? If there is a quality settings on unity? ( i m working on VR that i want to mention again)
