Verdict: The TCL QM8 65 outperforms the Hisense U6K 75 in HDR brightness (1,200 nits vs 800 nits per RTINGS) and offers HDMI 2.1, Dolby Vision, and HDR10+ support (CNET). While the Hisense provides a larger 75‑inch screen at a lower price, its lack of HDMI 2.1 and weaker HDR limit its appeal for premium viewing (Tom's Guide). Overall, the TCL delivers a stronger all‑round experience for bright‑room setups.
