The LG A2 offers superior dark room performance, better viewing angles, and exceptional black uniformity, making it excellent for movies and cinematic content. It, however, has a lower brightness, which might not be ideal for very bright rooms. In contrast, the Samsung QN90A shines in bright room conditions with its higher brightness and better handling of reflections. It also has a slightly better gaming performance due to a higher refresh rate. The QN90A is less expensive than the A2, which could be a compelling factor if budget is a concern. Consider the LG A2 if you value picture quality for movies in darker settings, but go for the Samsung QN90A for a better fit in well-lit rooms and gaming. Give Feedback

The LG A2 (OLED) is very good for sports, while the Samsung QN90A (LCD) is good.
The LG A2 OLED has an excellent response time and very good handling of reflections, which makes it great for watching sports as it provides clear motion and reduces distractions from lights or windows. The Samsung QN90A LCD, though good in motion processing and very good with reflections, doesn't match the OLED in response time or viewing angle, meaning the picture may not remain as consistent across different seating positions, but its higher brightness can be an advantage in very bright rooms.

The Samsung QN90A (LCD) is very good for gaming, while the LG A2 (OLED) is good.
The LG A2 OLED TV is appreciated for its excellent response time which is important for gaming as it means the display can quickly refresh and display new images, reducing motion blur, but its 60Hz refresh rate may limit gameplay smoothness compared to higher refresh rates. On the other hand, the Samsung QN90A LCD TV offers a very good response time as well, but excels in gaming due to its best-in-class input lag performance and a higher 120Hz refresh rate, which results in a more responsive gaming experience and smoother motion for fast-paced games.

The Samsung QN90A (LCD) is best in class for bright room, while the LG A2 (OLED) is good.
The Samsung QN90A is better suited for bright rooms due to its excellent SDR and HDR brightness levels and superior handling of reflections. The LG A2, with its OLED screen, offers perfect contrast and deep blacks that enhance viewing in lower light but doesn't match the Samsung's brightness, making it less ideal in well-lit environments.

The Samsung QN90A (LCD) and LG A2 (OLED) are both very good for news, talk, & other TV.
The LG A2 excels in upscaling lower-resolution content like news and talk shows, while also offering very good colors straight out of the box; this makes it suitable for standard dynamic range (SDR) content often seen in TV programming. On the other hand, the Samsung QN90A boasts superior SDR brightness and color accuracy which enhances the viewing experience, along with a robust contrast and local dimming feature that improves picture depth, even in bright rooms.

Al Griffin | August 2022
"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."
