LG QNED80 55" vs Vizio P-Series Quantum 65"
The Verdict
LG's QNED80 delivers impressive quantum dot technology in a more affordable 55-inch package, featuring native 120Hz refresh rate and responsive 10ms gaming performance. Vizio's P-Series Quantum counters with a larger 65-inch display, significantly brighter 1200-nit panel, superior full-array local dimming for contrast, and faster Wi-Fi 6 connectivity at a $300 premium. Gaming enthusiasts will appreciate the LG's slightly lower input lag (10ms vs 8ms is negligible), while the Vizio excels in picture quality through superior brightness and dimming zones. For movies and everyday viewing, Vizio's enhanced contrast capability and HDR10+ support make it the more versatile performer. Budget-conscious buyers wanting excellent performance should choose the LG; those prioritizing premium picture quality and willing to accommodate a larger footprint will find the Vizio superior.
