Mickey, you have to go to Netflix using a browser and mark your choice from low, medium, high and Auto. Unfortunately, (except for Auto) it affects all of your devices... so they are all the same. My iPhone 4 and 4S look ok at lower setting but my iPhone 5 I watched at the higher settings as I do with my Note 3. Since I have a friend on my account and she doesn't have wifi she always watches it at the low settings on her iPhone 4S to save usage. So we are alway switching back and forth for her setting and mine.
Not sure this will go through but hers a link:
support.netflix.com/en/node/87
Just in case, here is what that page states:
Manage Bandwidth Usage
If you are interested in setting a limit on how much data our service will use, you can adjust your video quality setting. Navigate to Your Account and click Playback Settings to manage the amount of data you use when playing movies and TV shows on Netflix.
There are 4 data usage settings to choose from:
Low (uses up to 0.3 GB per hour)
Medium (uses up to 0.7 GB per hour)
High (uses up to 1 GB per hour, up to 2.8 GB per hour if watching HD, or up to 4.7 GB per hour if watching 3D)
Auto (adjusts itself automatically to deliver the highest possible quality, based on your current internet connection speed.
Hope that helps! Have fun.
