Sony X90L 65" vs TCL 5-Series S555 65" (QLED)
The Verdict
Sony's X90L commands a significant premium at $1099 versus TCL's $599 S555, and delivers measurable advantages in peak brightness (1300 vs 800 nits) and superior Full Array LED backlighting that creates deeper blacks and better contrast than QLED. Sony's Cognitive Processor XR provides more refined upscaling and processing, while both share identical 8ms gaming input lag and VRR/ALLM support. TCL counters with newer Wi-Fi 6 connectivity, stronger raw speaker output (24W vs 20W), and exceptional value,delivering 4K 120Hz gaming at roughly 55% of Sony's cost. Picture quality differences favor Sony in bright rooms and HDR content, but the gap narrows in dark viewing environments. Choose the X90L for superior contrast and processor performance in a premium setup; select the TCL S555 for budget-conscious buyers seeking competent 4K gaming and streaming without sacrificing essential features.
