The LG B4 OLED 55 and the Samsung QN90B QLED 65 represent two distinct approaches to mid-range television performance. The LG B4 OLED 55 relies on its self-emissive panel to deliver perfect blacks. And precise pixel-level contrast, along with confirmed 120Hz refresh support and Dolby Vision HDR compatibility. In contrast, the Samsung QN90B QLED 65 uses a backlight array and quantum-dot layer to achieve higher overall luminance. And wider color volume, though its contrast remains limited by the inherent nature of LCD technology. Public reviews consistently note the LG’s superior motion clarity in fast-paced content. And more accurate out-of-box color tuning, while the Samsung is often praised for its brighter highlights in well-lit rooms. Neither manufacturer has published final peak-brightness figures for these specific models. The short version: choose the LG B4 OLED 55 if confirmed 120Hz refresh, Dolby Vision support, and pricing around $1,099.99 align with your priorities.

Verdict: Pick LG B4 OLED 55 if you need confirmed 120Hz refresh, Dolby Vision HDR, and known pricing at $1,099.99. Neither publishes peak brightness yet.
