Choose the LG NANO90 (LCD) if you prefer a more affordable option that performs well for gaming and in bright rooms, but note it won't be as impressive in dark room settings. Go with the LG B1 (OLED) for superior picture quality, especially in movies and dark room viewing, and better overall gaming performance, if you're willing to invest in a higher-priced TV. However, it won't be much brighter than the NANO90, which might be a concern in very well-lit environments. Give Feedback

The LG B1 (OLED) is very good for movies & TV, while the LG NANO90 (LCD) is poor.
The LG B1 OLED TV offers superior movie and cinematic TV viewing due to its perfect black uniformity and excellent contrast with true blacks, thanks to OLED technology, which allows for pixel-level dimming. In contrast, the LG NANO90 LCD TV, despite having local dimming, cannot achieve the same level of contrast and black uniformity, resulting in less impressive dark scene performance and a less immersive cinematic experience.

The LG B1 (OLED) is very good for sports, while the LG NANO90 (LCD) is only fair.
The LG B1 with its OLED screen provides an excellent response time and motion processing, making fast-paced sports scenes appear smoother and clearer, and its superior handling of reflections and wider viewing angles ensure a consistent picture quality from different seating positions. The LG NANO90, on the other hand, has decent motion processing but may not handle fast movements as smoothly due to the limitations of its LCD technology and might show more variation in picture quality when viewed from an angle.

The LG B1 (OLED) and LG NANO90 (LCD) are both very good for gaming, though the LG B1 (OLED) is somewhat better.
The LG NANO90 offers quick response times and very low input lag, ideal for gaming, and its 120Hz refresh rate keeps motion smooth, which is great for fast-paced games. In contrast, the LG B1 boasts even faster response times and equally low input lag, and thanks to its OLED technology, it provides superior picture quality with deeper blacks, although its peak brightness may be less suitable for very bright rooms.

The LG B1 (OLED) is very good for cartoons & animation, while the LG NANO90 (LCD) is poor.
The LG NANO90 LCD TV displays cartoons and animation poorly compared to the LG B1 OLED TV because the B1 offers superior color accuracy straight out of the box and a wider color range, which are very important for animated content. Moreover, the B1's OLED technology provides better color volume and contrast, as well as more uniform grays and blacks, further enhancing the viewing experience for brightly colored and vibrant animation.

Although they have very similar scores, PerfectRec considers LG B1 (OLED) to be good for bright room, while the LG NANO90 (LCD) is only fair.
The LG B1 OLED is rated as having excellent reflection handling and a perfect black uniformity, which makes it better for a bright room compared to the LG NANO90 LCD whose reflection handling is very good but with lower contrast performance due to its technology. Despite both having a similar SDR brightness, the OLED’s superior ability to handle reflections and provide deeper blacks gives it an advantage in well-lit environments.
