LG B4 55" vs TCL Q6 50"
LG's B4 OLED dominates with superior picture quality, delivering exceptional contrast through pixel-level dimming and 1100 nits peak brightness versus TCL's 600-nit QLED panel. Gaming performance heavily favors LG: 1ms input lag, 120Hz refresh rate, and full VRR support crush TCL's 14ms lag and 60Hz ceiling. Audio output matches at 2.0ch, but LG includes Dolby Atmos processing for enhanced spatial sound. TCL's Q6 compensates with affordability ($329 vs $1199), lighter construction (22 lbs), and adequate performance for general viewing. Both offer comparable smart TV ecosystems and connectivity options. At nearly 4x the price, LG delivers flagship OLED technology with gaming-centric features that justify premium positioning. However, TCL represents exceptional value for budget-conscious buyers prioritizing basic 4K content consumption. Serious gamers and cinephiles should choose the LG B4; casual viewers seeking budget 4K should consider the TCL Q6.
