Hisense U8N 65" vs TCL 5-Series S555 65" (QLED)
The Verdict
Hisense U8N delivers premium picture quality with Mini-LED backlighting, achieving 3000 nits brightness versus TCL's 800 nits, resulting in superior contrast, deeper blacks, and more impressive HDR performance across Dolby Vision IQ and HDR10+. Gaming capabilities favor the U8N with 144Hz refresh rate and 7ms input lag, though both support VRR and ALLM. Audio differs significantly: Hisense provides 60W with 2.1.2ch Dolby Atmos versus TCL's modest 24W stereo setup. TCL S555 compensates with exceptional value at half the price ($599 vs $1099), offering solid 4K gaming fundamentals and reliable Google TV performance for casual viewers. Build quality edges to Hisense's heavier construction (64.4 lbs), while TCL's thinner profile suits minimalist setups. For cinephiles and competitive gamers seeking premium visuals and immersive audio, the U8N justifies its premium. Budget-conscious buyers seeking capable mid-tier performance should choose TCL.
