Samsung QN90D 65" vs Vizio P-Series Quantum 65"
The Verdict
Samsung's QN90D dominates with its Neo QLED Mini-LED display delivering 4000 nits peak brightness versus Vizio's 1200 nits, resulting in superior contrast, color accuracy, and HDR impact. Samsung's Object Tracking Sound+ system (4.2.2ch, 60W) significantly outperforms Vizio's basic 2.0ch 20W setup for immersive audio. Gaming performance slightly favors Samsung with 5ms input lag compared to Vizio's 8ms, though both handle 4K@120Hz. Vizio counters with Wi-Fi 6, Dolby Vision support, and exceptional value at $999,nearly half Samsung's $1799 price. For cinephiles and gamers willing to invest, Samsung's superior picture quality and sound justify the premium. Budget-conscious buyers seeking solid 4K performance will find Vizio compelling. Samsung QN90D edges out as the better overall TV for discerning viewers.
