Hisense U7K 55" (Mini-LED ULED) vs LG B4 55"
The Verdict
Hisense U7K delivers impressive value with Mini-LED technology, achieving 1500 nits brightness and 144Hz refresh rate at a compelling $649 price point, making it excellent for bright rooms and competitive gaming. LG B4 counters with OLED's superior contrast and perfect blacks, though its 1100 nits peak brightness suits darker viewing environments better. Gaming performance strongly favors LG,its 1ms input lag dominates Hisense's 7ms response time, while both support VRR/ALLM. LG's webOS 24 with α8 processor and Filmmaker Mode offer more sophisticated smart features, but Hisense's Google TV provides broader compatibility. Audio specs marginally favor LG (40W vs 30W). For budget-conscious buyers prioritizing brightness and 144Hz gaming on a budget, Hisense U7K represents outstanding value. However, cinephiles and competitive gamers willing to spend more should choose LG B4 for its superior OLED panel and exceptional responsiveness. Hisense edges out for value seekers; LG wins for pure performance.
