LG OLED C3 65" (Evo) vs Sony X90K 65" (Full Array LED)
The Verdict
LG's OLED C3 and Sony's X90K represent different approaches to premium 65-inch 4K viewing. Picture quality heavily favors the C3, which leverages OLED technology for perfect blacks, infinite contrast, and superior color accuracy at 900 nits peak brightness versus Sony's 1200-nit Full Array LED panel. Sony counters with superior peak brightness for bright room performance and excellent motion handling. Gaming prowess slightly edges toward LG with 6ms input lag and OLED's instantaneous pixel response, though both support 120Hz VRR and ALLM. Audio leans Sony at 20W versus LG's 40W output, both featuring Dolby Atmos. Connectivity favors LG with Wi-Fi 6, Bluetooth 5.0, and superior port configuration. At $700 less, the X90K delivers impressive value for bright environments and sports enthusiasts. However, the C3's OLED superiority in contrast, color, and black levels justifies the premium for cinephiles and dark room viewing. Choose LG for uncompromising picture quality; select Sony for brightness performance and budget consciousness.
