LG OLED C2 65" (Evo) vs TCL 5-Series S555 65" (QLED)
The Verdict
LG's OLED C2 and TCL's 5-Series S555 both deliver 4K/120Hz gaming at 65 inches, but they operate in entirely different performance tiers. Picture quality favors the LG decisively,OLED technology produces infinite contrast, perfect blacks, and superior color accuracy compared to TCL's VA LCD panel, despite both hitting 800 nits peak brightness. Gaming performance is nearly identical with 6ms versus 8ms input lag and full VRR/ALLM support. Audio separation emerges as a notable differentiator: LG's 40W 2.2ch system with Dolby Atmos significantly outclasses TCL's 24W 2.0ch implementation. Smart TV experience slightly favors LG with webOS 22's superior app ecosystem and multiple voice assistants versus Google TV's single integration. TCL's $599 price point represents exceptional budget value for casual viewers, while LG's $1599 investment justifies itself through superior image quality, audio performance, and overall build quality. For serious movie enthusiasts, gamers, or anyone prioritizing picture quality, the OLED C2 is the clear winner. Budget-conscious buyers can comfortably enjoy the TCL without major regrets.
