LG QNED85 55" vs TCL 6-Series R655 55" (Mini-LED QLED)
The Verdict
Both 55-inch 4K TVs deliver impressive gaming performance with 120Hz refresh rates and 7ms input lag, but they diverge significantly in brightness and contrast capabilities. LG's QNED85 uses quantum dot technology with 700 nits peak brightness and delivers excellent color accuracy through its IPS panel, while TCL's 6-Series R655 leverages Mini-LED backlighting to achieve 1500 nits brightness,more than double,providing superior HDR impact and deeper blacks via VA panel technology. TCL edges ahead with Wi-Fi 6 connectivity and more robust 30W audio versus LG's 20W system. Gaming features are identical across both models. LG compensates with its refined webOS 23 interface supporting three voice assistants and slightly slimmer bezels. At $50 less, TCL offers exceptional brightness and gaming performance for dynamic content, while LG suits those prioritizing elegant design and color-focused viewing. For most buyers, TCL's Mini-LED advantage and value proposition make it the stronger choice.
