Low (0.3 GB per hour)
Medium (SD: 0.7 GB per hour)
High (Best video quality, up to 3 GB per hour for HD and 7 GB per hour for Ultra HD)
if you have capped bandwidth with overage charges and use netflix very frequently, this can add up to quite a large amount of bandwidth per month.
say you watch 4 hours a day on high but not ultrahd.. figure 1gb/hr * 4hr day * 30day month. that is 120gb/mo for a single 1080p stream.
say you watch ultra hd for 4 hours a day? that could be 340gb up to 840gb/mo
we are unlimited data, so are unaffected though some people with capped data should certainly give it thought.
not sure if settings set on pc for netflix will transfer over to your tv or not - you will need to look that up.
