Samsung QN85C 65" (4K Neo QLED) vs Vizio OLED 55"
The Verdict
Samsung's 65-inch Neo QLED delivers superior brightness at 1200 nits compared to Vizio's 600-nit OLED panel, making it better for bright rooms and HDR content with more vibrant peak highlights. The larger screen size adds viewing presence that matters in most living rooms. Samsung includes a more powerful audio system with 60 watts and 2.2 channel Object Tracking Sound versus Vizio's modest 30-watt 2.0 setup. Both handle gaming equally well with 9-10ms input lag and full VRR/ALLM support at 120Hz. Where Vizio excels is contrast and black levels through true OLED technology, which produces perfect blacks and superior color accuracy that many will prefer for movies in darker environments. Vizio also includes Wi-Fi 6 versus Samsung's Wi-Fi 5, and costs $400 less at $999. For most buyers seeking larger screens, brighter performance, and robust audio in typical living rooms, the Samsung QN85C offers better value and versatility. However, cinephiles prioritizing pristine contrast and black levels in controlled lighting should consider the Vizio despite its smaller 55-inch format.
