LG OLED B3 65" vs Sony X90L 65"
The Verdict
Both 65-inch 4K TVs deliver compelling value at their respective price points, but they excel in different areas. LG's OLED B3 showcases superior contrast and color accuracy with perfect blacks thanks to its WOLED panel, making it exceptional for movies and dark room viewing. Sony's X90L counters with dramatically higher peak brightness (1300 nits vs 600 nits), superior local dimming through full array LED backlighting, and the advanced Cognitive Processor XR for upscaling. Gaming performance is nearly identical with 7-8ms input lag and full VRR/ALLM support. Audio is matched at 20W with Dolby Atmos. Sony edges ahead for bright rooms and sports due to brightness advantage, while LG dominates cinematic content. At $200 less, Sony X90L offers superior value for general viewing, though OLED purists and dark-room enthusiasts should prefer the B3. For most buyers seeking a balanced 65-inch flagship, Sony X90L is the smarter choice.
