The LG OLED65B4 and the Samsung QN65QN90B are both 65-inch 4K televisions that rely on fundamentally different panel technologies, with the former using LG’s self-emissive OLED panel. And the latter employing Samsung’s Mini-LED backlit VA LCD. Public specifications and aggregated user reviews indicate the LG OLED65B4 delivers perfect blacks. And wide viewing angles typical of OLED designs, while the Samsung QN65QN90B achieves higher peak brightness and stronger anti-glare performance suited to brighter rooms. Feature sets overlap in areas such as HDMI 2.1 ports, variable refresh rate support, and smart-platform integration, yet each ties its interface and ecosystem features to its manufacturer’s broader lineup of devices. Review roundups note differences in color volume, motion handling, and gaming latency that remain consistent with the underlying panel strengths of each model. The short version: choose the LG OLED65B4 if you favor LG’s ecosystem or the Samsung QN65QN90B if Samsung’s platform aligns better with the rest of your setup.

Verdict: The LG OLED65B4 still excels in pure black performance, so it’s the better choice for dark‑room cinephiles who prioritize contrast over brightness.
