The LG A2 OLED TV generally provides better picture quality, specifically in dark rooms, and enhances the experience for movies and series due to its perfect blacks and excellent contrast. It also has wider viewing angles, which is great for gatherings. However, the A2 is at a higher price point and may not perform as well in very bright rooms compared to the LG NANO90. On the other hand, the LG NANO90 LCD TV is less expensive and offers better performance for gaming due to a higher refresh rate, which is beneficial for fast-paced content. Its bright room performance is also slightly better than the A2. However, it falls short in picture quality in dark environments and overall is not as strong in contrast and picture quality for movies and series as the A2. It might also be less impressive when viewing from angles. If you watch a lot of movies in dark rooms and appreciate superior picture quality, the LG A2 is a good choice despite its higher cost. Alternatively, if you're looking for a more budget-friendly option with better gaming performance and decent bright room viewing, the LG NANO90 is a suitable option. Give Feedback

The LG A2 (OLED) is excellent for movies & TV, while the LG NANO90 (LCD) is poor.
The LG A2 OLED's perfect contrast and excellent black uniformity ensure deep blacks and high detail in dark scenes, essential for movies and cinematic content, complemented by its superior viewing angles that preserve color and contrast when seen from the side. In contrast, the LG NANO90 LCD struggles with lower contrast and black uniformity, leading to grayer blacks and less detail in dark areas, and while its local dimming attempts to improve dark scene performance, it's less effective compared to the A2's capabilities.

The LG A2 (OLED) is very good for sports, while the LG NANO90 (LCD) is only fair.
The LG A2 OLED provides an overall much better experience for watching sports due to its superior response time and excellent motion processing, which result in clearer images with little blur during fast action. In contrast, the LG NANO90 LCD, while having a good response time and fair motion processing, doesn't perform as well with reflections and has a narrower viewing angle, which can detract from the viewing experience in a bright room and when viewed from the side.

The LG NANO90 (LCD) is very good for gaming, while the LG A2 (OLED) is good.
The LG A2 OLED has excellent response time and very good input lag, making it good for gaming, but the LG NANO90 LCD edges out due to a 120Hz refresh rate compared to the A2's 60Hz, which is very important for a smoother gaming experience and makes it very good for gaming despite both TVs having similar response time and input lag performance.

The LG A2 (OLED) is very good for cartoons & animation, while the LG NANO90 (LCD) is poor.
The LG A2 stands out for cartoons & animation because its OLED technology provides very good colors out of the box and a very good color gamut, which enhances the vibrancy and depth of animated content. On the other hand, the LG NANO90, with its LCD screen, delivers poor colors out of the box and only a fair color gamut, resulting in less accurate and less vivid animations.

The LG A2 (OLED) is very good for news, talk, & other TV, while the LG NANO90 (LCD) is only fair.
The LG A2 OLED is very good for watching news and TV programs due to its perfect blacks and excellent upscaling of low-resolution content, alongside better colors out of the box and a wider color gamut. In contrast, the LG NANO90 LCD is only fair in this regard, with lower contrast and less impressive colors out of the box that might make the viewing experience less striking, especially in dimly lit rooms.

Although they have very similar scores, PerfectRec considers LG A2 (OLED) to be good for bright room, while the LG NANO90 (LCD) is only fair.
The LG A2 OLED, while good at handling reflections, has poorer SDR and HDR brightness than the LG NANO90 LCD, thus performance in a bright room is not as strong. The NANO90 LCD offers better SDR and HDR brightness levels and also handles reflections well, making it more suitable for bright environments.

"Movie fans will find a lot here to love, and the A2 series’ low prices compared with other OLED TVs will keep their wallets happy. Images had the deep blacks and detailed shadows typical of the best 4K TVs, while colors looked both fully saturated and clean. Also, the A2’s out-of-box picture performance in Filmmaker mode was mostly accurate, requiring only slight adjustments to optimize brightness, color, and contrast."

"Here we have HDR pictures that look bright, but also manage to typically hit decently deep black levels.WebOS continues, though, to be one of the easiest to use. Connections are strong for a mid-range TV. Native 4K pictures look crisp and detailed."
