The LG 65" G1 Gallery Series OLED 4K TV relies on self-emissive pixels that deliver perfect blacks and infinite contrast, paired with a 120Hz native panel. And the established webOS platform that draws consistent praise in public reviews for its speed and app support. In contrast, the TCL QM851G 55" Mini LED TV uses an aggressive local-dimming backlight with hundreds of zones to approximate deep blacks on a LCD panel, offers a more compact 55-inch footprint. And typically carries a lower price point according to retail specifications and aggregated buyer feedback. Differences in screen size, contrast purity, motion clarity, and long-term platform reliability emerge clearly when the two models are placed side by side in review roundups. The short version: choose the LG 65" G1 Gallery Series OLED 4K TV for superior OLED picture quality. And proven 120Hz performance, or select the TCL QM851G 55" Mini LED TV when a smaller, more affordable set fits the room and budget.

Verdict: Pick LG 65" G1 Gallery Series OLED 4K TV if you need OLED technology, 120Hz refresh and a proven smart platform (120Hz vs unknown). Pick TCL QM851G 55" Mini LED TV if you prefer a smaller screen and potentially lower cost, though exact pricing and specs are not published. Neither publishes peak brightness, HDMI 2.1 ports or VRR / ALLM yet.
