Verdict: The LG C5 OLED 77" outperforms the Hisense A6 in every core metric—contrast, refresh rate, and feature set—making it the clear choice for high‑end home theater or gaming (RTINGS contrast ratio 1,000,000:1 vs 1,200:1; Tom's Hardware HDMI 2.1 latency 9 ms vs 18 ms). However, the Hisense A6 offers a far lower entry price and decent brightness for bright‑room viewing, which may suit cost‑conscious buyers. Overall, LG’s premium performance justifies its higher cost for enthusiasts, while Hisense remains a solid budget alternative.
