Recommendations

Place the TV at an appropriate viewing distance for a 77" screen to benefit from 4K detail while avoiding eye strain; avoid prolonged high‑brightness HDR playback to limit energy consumption and potential image retention in OLED panels. Use automatic or calibrated picture modes for accurate color and consider regular software updates via Tizen to maintain feature and security updates.
