LG QNED85 55" vs Sony X85K 65" (LED)
The Verdict
LG's QNED85 delivers impressive mid-range performance with quantum dot technology and NanoCell IPS panels, achieving 700 nits brightness and excellent 7ms gaming input lag at 55 inches for $799. Sony's X85K steps up to 65 inches with direct LED backlighting, matching brightness and gaming specs (10ms lag) but using a traditional LED approach rather than quantum dots. Both support 4K/120Hz, Dolby Vision, and Dolby Atmos with comparable 20W audio. Key differences: LG's superior QNED panel technology and smaller form factor justify premium picture quality for smaller rooms, while Sony's larger 65-inch screen and Google TV ecosystem appeal to those wanting more screen real estate. Gaming performance favors LG slightly with faster response times. At $200 more, Sony's size advantage matters most if your space permits,otherwise, LG's QNED technology and value proposition make it the smarter choice for picture quality per dollar.
