LG OLED A2 55" vs TCL 5-Series S555 65" (QLED)
The Verdict
LG's A2 OLED delivers superior picture quality with perfect blacks and exceptional contrast inherent to OLED technology, plus Dolby Atmos audio and webOS's refined interface. However, TCL's 5-Series S555 offers compelling value with a larger 65-inch QLED panel, 120Hz refresh rate with VRR support, significantly brighter 800-nit peak brightness ideal for well-lit rooms, and lower input lag of 8ms for gaming. At $300 less, the TCL includes more HDMI ports and Wi-Fi 6 connectivity. Choose the LG for premium picture quality and smaller room viewing, but the TCL represents better overall value for gaming enthusiasts and those prioritizing screen size and brightness performance.
