Sony X85K 65" (LED) vs Vizio P-Series Quantum 65"
The Verdict
Both 65-inch 4K TVs arrive at the same $999 price point but diverge meaningfully in display technology and gaming performance. Sony's X85K uses Direct LED with an IPS panel delivering 700 nits brightness and 10ms input lag, paired with 20W Dolby Atmos audio and Google TV's intuitive interface. Vizio's P-Series Quantum employs Full Array Local Dimming with VA panel technology, achieving significantly higher 1200 nits brightness and superior 8ms input lag for gaming,critical advantages for competitive titles. Vizio's Quantum Color LED with HDR10+ support also produces richer contrast and color volume. However, Sony offers a more premium audio experience with Dolby Atmos, while Vizio's SmartCast feels less refined than Google TV. Vizio's Wi-Fi 6 and Bluetooth 5.0 provide better connectivity. For gaming-focused buyers prioritizing response time and visual impact, Vizio's superior local dimming and brightness make it the compelling choice. Sony edges ahead for media streamers who value audio quality and software fluidity.
