Verdict: The LG B5 OLED scores higher overall, thanks to its true‑black performance (infinite contrast per RTINGS) and wider viewing angles (per RTINGS), while the Hisense U6K offers a brighter panel (380 nits peak per RTINGS) at a lower price. In bright rooms the U6K’s Mini LED can be more visible, but in dark environments the B5’s OLED superiority is clear. For most users seeking the best picture quality, the B5 is the stronger choice.

Winner: LG B5 OLED

Hisense U6K Mini LED 75: 7/10

LG B5 OLED: 8/10
