The LG 55CXPUA OLED 55" TV and the Samsung QN55QN90B each bring distinct strengths to the 55-inch premium television category. Public reviews consistently praise the LG 55CXPUA OLED 55" TV for its perfect blacks, infinite contrast. And wide viewing angles that stem from its OLED panel, while noting its $1,799.99 price as a known quantity. In contrast, the Samsung QN55QN90B relies on Mini-LED backlighting to deliver higher peak brightness suitable for rooms with strong ambient light, along with solid color volume. And gaming features, though its exact street price remains unpublished at the time of most comparisons. Both sets support 4K at 120 Hz, variable refresh rates, and low input lag, yet they diverge in how they handle motion, reflection control. And long-term panel longevity according to aggregated expert analyses. The short version: choose the LG 55CXPUA OLED 55" TV for deep cinematic blacks in controlled lighting or the Samsung QN55QN90B when brightness in challenging environments matters more.

Verdict: Pick LG 55CXPUA OLED 55" TV if you value OLED picture quality and can work with the known $1,799.99 price. Pick Samsung QN55QN90B if you prefer a brighter display for well‑lit rooms and are comfortable without a published price.
