The LG B2 OLED TV might be a better value if you're looking for excellent picture quality, especially in viewing movies and TV shows in darker rooms, due to its superior contrast ratios and deeper blacks. However, the Samsung QN90A LCD, despite often being somewhat more expensive, may offer a better experience in bright rooms because of its higher brightness levels. Additionally, for sports and gaming content, the Samsung QN90A's responsive technology may give a slight edge if you're looking for crisp, fast-moving images. Both TVs support high-resolution gaming, but for the best dark room performance, the LG B2 would be more suitable. Give Feedback

The LG B2 (OLED) is excellent for movies & TV, while the Samsung QN90A (LCD) is very good.
The LG B2 OLED excels in watching movies and cinematic TV due to its perfect black uniformity and effective local dimming, ensuring deep blacks and excellent contrast, which is crucial in dark viewing environments. On the other hand, while the Samsung QN90A LCD also performs well with contrast and local dimming, it doesn't quite match the LG's pure blacks and wide viewing angles, though it still delivers a very good cinematic experience.

The LG B2 (OLED) is very good for sports, while the Samsung QN90A (LCD) is good.
The LG B2 is excellent for watching sports due to its perfect response time and wide viewing angles, attributes that are crucial for fast-paced action and group viewings, while the Samsung QN90A, although still very good in response time and with superior capabilities in handling reflections making it more versatile in bright rooms, doesn't have as wide viewing angles, which might limit the viewing experience for larger groups. Gray uniformity, which affects how well a TV displays solid colors over the screen and is somewhat important for sports viewing, is excellent on both models, ensuring a consistent picture quality across their screens.

The LG B2 (OLED) and Samsung QN90A (LCD) are both very good for gaming, though the LG B2 (OLED) is somewhat better.
The LG B2 OLED TV excels in response time, providing the best performance for gaming where fast-moving images are smooth and clear, making it an excellent choice for fast-paced action, though it has slightly higher input lag compared to the Samsung QN90A. The Samsung QN90A LCD TV, on the other hand, offers the best input lag which is crucial for gaming responsiveness, especially for competitive gaming, but doesn't have the superior response time of the LG B2.

The Samsung QN90A (LCD) is best in class for bright room, while the LG B2 (OLED) is good.
The Samsung QN90A excels in a bright room due to its superior SDR and HDR brightness, which allows it to maintain picture quality despite ambient light. Both the LG B2 and Samsung QN90A handle reflections exceptionally well, but the LG B2's inherent high contrast courtesy of its OLED screen makes it a good fit for bright rooms, albeit less bright than its Samsung LCD counterpart.

The Samsung QN90A (LCD) and LG B2 (OLED) are both very good for news, talk, & other TV.
The LG B2 OLED TV excels in upscaling and providing deep contrasts with its perfect blacks, which enhances the viewing experience for news and talk shows, but its lower SDR brightness could make it less ideal for very bright rooms. Conversely, the Samsung QN90A LCD TV offers very bright SDR output, which is advantageous in bright environments, alongside strong upscaling and good colors out of the box, although it might not deliver the same level of contrast as the LG B2 due to its backlighting technology.

Tom's guide
Nick Pino | March 2023
"The LG B2 OLED pairs lush, saturated colors and perfect contrast with a 120Hz screen, HDMI 2.1 ports and a great smart TV platform. The LG B2 OLED is an ideal alternative to the LG C2 OLED for folks who want a taste of OLED life without the sticker price that usually comes with it. The LG B2 OLED does a lot right in terms of performance, color saturation is wonderful and contrast is second-to-none. Not only did color saturation and off-axis viewing impress me, harder to quantify specs like motion processing and upscaling really blew me away as well."
