When choosing between the LG A1 and LG B3, consider the following aspects: The LG B3 offers a higher refresh rate, which is excellent for sports and gaming, providing a smoother picture. It also has slightly better performance in brighter rooms and supports a more responsive gaming experience with higher frame rates. On the other hand, the LG A1 is more budget-friendly. However, it won't be as suitable for fast-paced content and might not handle reflections in sunny rooms as effectively as the B3. If those features outweigh the price difference, the LG B3 would be a better choice. Give Feedback

The LG B3 (OLED) is very good for gaming, while the LG A1 (OLED) is good.
The LG A1 has a lower refresh rate of only 60Hz and is possibly graded lower for gaming responsiveness indicated by metrics like response time and input lag than the LG B3, which supports a higher 120Hz refresh rate, typically providing smoother motion ideal for gaming. Consequently, the LG B3's more responsive gaming performance on these metrics makes it more suitable for high-speed gaming that benefits from quicker screen updates and better interaction response.

The LG B3 (OLED) and LG A1 (OLED) are both very good for cartoons & animation, though the LG B3 (OLED) is somewhat better.
The LG A1 and LG B3 OLED TVs are very good for watching cartoons and animation due to their strong performance in crucial areas; the A1 delivers good colors straight out of the box and a very good color gamut, while the B3 excels with very good scores for both colors out of the box and color gamut. Additionally, the B3 has a very good color volume, which is somewhat important, indicating richer colors across a wider range, and this alongside excellent contrast and gray uniformity, slightly edges out the A1, enhancing the overall viewing experience for colorful animated content.

Although they have very similar scores, PerfectRec considers LG B3 (OLED) to be excellent for movies & TV, while the LG A1 (OLED) is very good.
The LG A1 provides very good movie and cinematic TV watching experience with its perfect contrast, local dimming, and black uniformity, which contribute to exceptional dark room viewing, reinforced by good color accuracy right out of the box and wide viewing angles. The LG B3, however, enhances this experience with slightly better gray uniformity and color volume, which means richer colors and more nuanced gray shades, making it excellent for the same viewing circumstances.
