Hi Mike, We appreciate your feedback regarding your U8000FD TV’s performance. If you're experiencing freezing or lag in general response time, please try the following steps: 1. Check for firmware updates – Keeping your TV up to date can resolve many performance issues: Home > left directional key > Settings > Support > Software Update > Update Now 2. Run Device Care – This tool checks system memory, frees up cached data, and closes background apps that could be slowing things down: Home > left directional key > Settings > Support > Device Care > Start Device Care 3.
