The TCL QM851G Mini LED 55 wins decisively with 144 Hz refresh rate and thousands of dimming zones versus the Hisense A6's basic 60 Hz LED panel (RTINGS 2025 review). It excels in bright rooms with 2000+ nits peak brightness while the Hisense stays under 400 nits. The Hisense A6 suits only the tightest budgets under $400.
