LG OLED B3 65" vs TCL 6-Series R655 55" (Mini-LED QLED)
The Verdict
LG's OLED B3 delivers superior picture quality with perfect blacks and exceptional contrast that Mini-LED simply cannot match, though its 600-nit peak brightness trails the TCL's impressive 1500 nits in bright rooms. Gaming performance is virtually identical between both models, each offering 7ms input lag, VRR, and ALLM support at 120Hz. Picture quality decidedly favors the OLED technology for movie watching and gaming in darker environments. However, the TCL 6-Series R655 presents remarkable value at $749 for a 55-inch Mini-LED with superior brightness, more powerful audio (30W vs 20W), and Wi-Fi 6 connectivity,though its smaller screen and LCD panel technology mean less refined blacks. For cinephiles prioritizing display excellence and willing to spend $550 more, the 65-inch B3 is the clear choice. Budget-conscious buyers seeking brightness and gaming versatility should consider the TCL, accepting minor picture quality compromises for significant savings.
