LG QNED85 55" vs Vizio M7 Q-Series 55"
The Verdict
LG's QNED85 delivers superior picture quality with 700 nits brightness, quantum dot technology, and full-array local dimming that outperforms Vizio's VA panel at 600 nits. Gaming enthusiasts will appreciate the LG's 120Hz refresh rate, 7ms input lag, and VRR support versus Vizio's 60Hz limitation and 12ms lag. Audio is equivalent at 20W 2.0ch, though LG includes Dolby Atmos processing. Vizio compensates with $300 lower pricing, Wi-Fi 6 connectivity, and respectable HDR10+ support. Both offer solid 4K resolution and smart TV features with major voice assistants. At $799, the LG QNED85 justifies its premium through noticeably better contrast, motion handling, and gaming performance. Choose LG for premium home theater and gaming; select Vizio if budget constraints matter more than peak performance.
