Verdict: The TCL QM851G outshines the Hisense A6 in brightness, HDR support, and motion handling, delivering up to 1,200 nits (RTINGS) and 120 Hz refresh (Tom's Guide) versus the A6’s 350 nits and 60 Hz. While the Hisense is cheaper and adequate for low‑light rooms, the TCL’s Mini‑LED panel and HDR10+/Dolby Vision make it a clearer winner for bright spaces. Both are priced similarly on the used market, but the TCL provides far more visual performance.
