I'm tired of seeing people posting topics about Netflix streaming poor quality...
First did you try the search bar?
-Netflix quality is determined by the SPEED OF YOUR INTERNET not just your tv.
-when your internet speed drops Netflix re-adjusts to a lower quality so that it can stream without hickups
If you have bad quality streaming here are 2 solutions
1.Back out of the movie and then resume. It should take you back to full quality
2.Get faster internet
Simple as that
