LG C4 65" vs Samsung S90C 65" (4K OLED)
The Verdict
Both 65-inch OLED TVs deliver exceptional picture quality, but they excel in different areas. LG's C4 features the α9 Gen 7 processor with superior upscaling, 1300-nit peak brightness, and more robust 60W audio with 2.2ch configuration. Samsung's S90C counters with a brighter QD-OLED panel (1500 nits), faster 144Hz gaming mode, and slimmer design at 40.6 lbs versus LG's 52.9 lbs. Gaming performance favors LG with 1ms input lag versus Samsung's 6ms, though Samsung's higher refresh rate appeals to competitive gamers. Audio quality leans toward LG's superior speaker setup. The $200 price difference puts LG ahead on value proposition, offering comparable picture quality with better processing, gaming response, and sound for less money. Choose LG C4 for best overall value and gaming; select Samsung S90C if maximum brightness and ultra-thin aesthetics justify the premium.
