How can I manage my Internet usage when using Netflix on Fibe TV?
When using Netflix, video quality directly affects data usage. Standard definition (SD) uses about 1 GB per hour; high definition (HD) uses about 3 GB per hour.
Adjusting the data usage settings within your Netflix account is the easiest way to control the amount of data used while watching Netflix. To change your data usage, log in to Netflix at netflix.com and select Playback Settings. Playback settings will apply to all devices you use to access your Netflix content.
