TCL Q6 50" vs TCL S4 55"
The Verdict
Both TCL models deliver 4K resolution and Google TV at compelling price points, but serve different priorities. Picture quality favors the Q6, which uses QLED technology with 600 nits brightness compared to the S4's basic LED panel at 400 nits,meaningful for HDR performance and daylit viewing. Gaming performance tilts toward the Q6 with its 14ms input lag and ALLM support versus the S4's sluggish 30ms response and missing ALLM. Audio output is superior on the Q6 (20W vs 15W). However, the S4 offers a larger 55-inch screen for $50 less, appealing to budget-conscious buyers prioritizing screen real estate over picture quality. The Q6's AiPQ processor also outperforms the S4's lite variant for upscaling and processing. For gamers and those valuing premium visuals, the TCL Q6 50" is the stronger recommendation. Those needing maximum screen size on a tighter budget should consider the S4, accepting compromised brightness and gaming responsiveness.
