Verdict

Its Mini-LED panel, high peak brightness, extensive local dimming and 165Hz gaming support give it a clear specification advantage. The 55S7SG remains a capable choice for users who want Google TV, 144Hz gaming and strong smart features without needing the higher-end display and audio capabilities of the U7SF.
