Once you’re on your Admin account, you’ll be brought to your Netflix home page. Now click your profile name at the top-right of the screen .

Toward the bottom of the page, under the My Profile header, you’ll find an option for “Playback settings.” Click that to make your choice. 7. Choose Your Desired Playback Quality. By default, Netflix sets the playback quality to Auto, allowing you to get the best visual experience based on your network’s capabilities and default settings in the app. Aside from Auto, Netflix gives you three data usage options based on your desired usage. Low (Basic video quality, up to 0.3 GB per hour of usage) Medium (Standard video quality, up to 0.7 GB per hour of usage) High (Best video quality, up to 3 GB per hour for HD, 7 GB per hour of Ultra HD) Now’s the time to check your data usage, see how much data you actually want to consume, and pick your option. The setting will be applied to your account and will determine the quality of your content. The lower the option you choose, the worse the video quality. You might also want to consider whether to keep the Auto-Play option toggled. By default, it’s set to on. If you’re worried about data usage, toggle off that option. 8. Click Save. Now that you’ve chosen your video-quality option, click save. Your video quality and data usage will now be governed by that setting.
