LG QNED80 55" vs Sony X90L 65"
The Verdict
LG's QNED80 delivers solid quantum dot picture quality at 700 nits brightness with native 120Hz gaming performance and 10ms input lag, making it an excellent mid-range choice for both movies and competitive gaming. Sony's X90L significantly outperforms it with double the brightness at 1300 nits, superior Full Array LED dimming, Dolby Atmos audio support, and 8ms input lag,plus a larger 65-inch panel versus 55 inches. Both handle 4K/120Hz gaming with VRR and ALLM, but the X90L's more advanced processor and brighter HDR performance justify its premium $400 price difference for those demanding the best picture quality. For budget-conscious buyers comfortable with smaller screens and slightly less peak brightness, the QNED80 offers tremendous value. However, serious home theater enthusiasts and gamers seeking best-in-class performance should invest in the Sony X90L's superior HDR capability and immersive audio.
