When using Netflix from a computer browser (e.g. Chrome, Firefox, IE, etc.), it will automatically stream content based on your internet download speed. This ensures smooth playback that isn’t interupted by annoying ‘buffering’ pauses.
It can sometimes get it wrong though. If you prefer to wait for prebuffering, then you can force it to use a higher bitrate – even an HD setting.
Instructions for Windows
