Most Smart TVs ship with settings tuned for general use, not sustained streaming. A few adjustments can noticeably reduce buffering.
Network
Use 5GHz Wi-Fi over 2.4GHz where available, or better yet, a wired Ethernet connection. Restart your router monthly to clear accumulated connection issues.
Picture processing
Some TVs apply heavy motion-smoothing or upscaling that adds latency. If you notice input lag or stutter, try switching to a simpler "Standard" or "Movie" picture mode.
Background apps
Close other streaming or casting apps running in the background — many Smart TVs keep several apps active simultaneously, competing for bandwidth and memory.
