Quality Settings

You can enable auto quality, choose a starting quality, and limit data usage in the Quality section of your client app.

  • Automatically Adjust Quality: Turn on or off the Automatically Adjust Quality feature that increases or decreases video quality based on your connection speed. When enabled, auto quality will be used on servers with Plex Media Server v1.8.1 or later. Playback on older servers will not be affected.
