Hisense U8N 65" vs LG OLED B3 65"
The Verdict
Both 65-inch 4K TVs deliver excellent gaming performance with 7ms input lag and VRR support, but they excel in different areas. Hisense U8N leverages Mini-LED technology with exceptional brightness (3000 nits) and superior HDR support including IMAX Enhanced, making it ideal for bright rooms and competitive gaming with its 144Hz refresh rate. LG OLED B3 prioritizes pure picture quality through its self-emissive OLED panel, delivering infinite contrast and perfect blacks at 600 nits,outstanding for dark room viewing and movies. U8N dominates audio with 60W 2.1.2ch speakers versus B3's modest 20W 2.0ch setup. LG includes better smart TV integration with three voice assistants and webOS's refined interface. Gaming-wise, both perform identically. LG's ultrathin 1.8-inch profile adds aesthetic appeal. For bright gaming environments where HDR peak brightness matters, choose the Hisense U8N. For cinema-quality contrast and dark room excellence, the LG OLED B3 justifies its $200 premium.
