The LG A1 OLED might be a better choice if you primarily watch movies and series or if you'll be viewing in a dark room, as OLED TVs offer superior contrast, black uniformity, and wide viewing angles. However, the NANO90 LCD is a better fit for sports, gaming, or bright room usage due to better motion handling and a brighter screen. The NANO90 is also typically less expensive than the A1. On the downside, the A1 may not be as suitable in bright rooms, and the NANO90 may not offer the same level of picture quality in darker environments. Give Feedback

The LG A1 (OLED) is very good for movies & TV, while the LG NANO90 (LCD) is poor.
The LG NANO90's LCD display with lower contrast, inadequate local dimming, and poor black uniformity leads to less satisfying movie and cinematic TV watching experiences compared to the LG A1, which, as an OLED TV, excels in all these aspects providing deeper blacks and more vivid colors enhancing the overall viewing experience. Viewing angles and color accuracy are better on the LG A1 as well, making it more suitable for wider seating arrangements and critical viewing where color fidelity is crucial.

The LG A1 (OLED) is very good for sports, while the LG NANO90 (LCD) is only fair.
The LG A1 OLED is better for watching sports due to its excellent response time and wide viewing angles which ensure clear images even during fast movement and when viewed from the side, while also handling reflections very well. Conversely, the LG NANO90 LCD has good response time and viewing angles but does not manage reflections or motion processing as effectively as the A1, leading to a less optimal experience for sports viewing.

The LG NANO90 (LCD) is very good for gaming, while the LG A1 (OLED) is good.
The LG NANO90 has a good response time and very low input lag, making it well-suited for fast gaming sessions, while the LG A1 boasts an excellent response time and the best input lag, offering an even smoother gaming experience. The NANO90's higher refresh rate at 120Hz may benefit fast-paced games, but the A1's OLED technology provides superior image quality with more fluid motion handling, despite having a 60Hz panel.

The LG NANO90 (LCD) and LG A1 (OLED) are both only fair for bright room.
When watching TV in a bright room, the LG NANO90 LCD handles reflections better and provides higher SDR and HDR brightness, which is beneficial for keeping the picture visible despite ambient light. On the other hand, the LG A1 OLED offers superior contrast and more vibrant colors, but it doesn't get as bright and may struggle more with reflections, leading to a potentially less optimal viewing experience in well-lit environments.
