LG UR8000 55" (UHD) vs TCL S4 55"
The Verdict
Both 55-inch 4K TVs deliver solid budget-friendly performance, but they target different priorities. LG UR8000 ($399) features superior webOS 23 interface with LG ThinQ AI, better input lag at 15ms, and IPS LCD panel consistency, making it ideal for smart home integration and general viewing. TCL S4 ($279) counters with brighter 400-nit display, superior HDR support including Dolby Vision, and a $120 price advantage,though its 30ms input lag and Google TV OS are less polished. Picture quality slightly favors TCL thanks to higher brightness and wider HDR coverage, while LG excels in software responsiveness and gaming performance. For budget shoppers prioritizing value and HDR content, TCL S4 offers exceptional bang-for-buck. Those wanting better interface fluidity and gaming-friendly responsiveness should stretch to the UR8000. TCL S4 is the stronger recommendation for most buyers seeking maximum value.
