The LG B2 OLED offers deeper contrasts and better performance in dark rooms than the Samsung Q70A LCD, especially valuable for movies and series watching. However, the B2 is less bright, making it less ideal in very sunny rooms compared to the Q70A, which is brighter. The B2 has outstanding gaming features and viewing angles, suitable for gamers and those with wide seating. On the other hand, the Q70A costs less, but it does not perform as well overall in picture quality as the LG B2. If the budget allows and picture quality is a priority, the LG B2 is the better option, but for brighter environment viewing at a lower cost, consider the Samsung Q70A. Give Feedback

The LG B2 (OLED) is very good for sports, while the Samsung Q70A (LCD) is only fair.
The LG B2 OLED TV stands out for sports watching with its superior response time and excellent handling of reflections which help maintain a clear picture during fast-paced games, along with a wide viewing angle that keeps the picture consistent for viewers spread across the room. In contrast, the Samsung Q70A LCD TV might show more motion blur due to its lower response time and has a narrower viewing angle, meaning the image might look less accurate when seen from the side.

The LG B2 (OLED) is very good for gaming, while the Samsung Q70A (LCD) is good.
The LG B2 OLED boasts a top-tier response time, making motion appear very smooth in games, while its input lag is low, offering quick reactions to gaming inputs, and its 120Hz refresh rate makes it ideal for fast-paced gaming. On the other hand, the Samsung Q70A LCD also has a very good response time and even lower input lag, but its screen type may not provide the same level of motion clarity as the LG B2 OLED, especially in darker gaming scenes.

The LG B2 (OLED) is very good for news, talk, & other TV, while the Samsung Q70A (LCD) is good.
The LG B2 OLED delivers exceptional contrast and true blacks, providing a more immersive viewing experience for news and talk shows, with good performance for upscaling lower-resolution content, while the Samsung Q70A LCD excels in SDR brightness, which is beneficial for well-lit rooms, but doesn't have the same deep black levels due to its lack of local dimming. Both models offer good color accuracy out of the box, with the LG B2 OLED having a slight edge in upscaling and the Samsung Q70A performing better in brighter environments.

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."
