To stream 1080p or 4K content smoothly on your TV, tablet, or phone, it's important to optimize your Plex settings. A high-speed internet connection and strong link to the remote Plex server are essential.
🔧 Tip: If you're experiencing buffering or stuttering, your internet connection might not be fast enough — or your settings need adjusting.
- Turn off "Adjust Quality Automatically" for better control.
- Set Remote Quality and Local Quality to Original or Maximum.
- Enable Direct Play and Direct Stream wherever possible.
Note: Plex settings may vary slightly across devices.
