The LG A2 OLED offers excellent overall picture quality, superior for movies and series, and has a perfect contrast ratio, which makes it a great fit for watching content in dark rooms. Its viewing angles are also wide, beneficial if you have a wide seating arrangement. However, the Sony X90J LCD has a higher peak brightness, making it a better choice for bright rooms, and has a better gaming performance due to its higher refresh rate. Moreover, it is less expensive. Neither TV supports HDR10+ but both support Dolby Vision, HLG, and they have a similar sound quality. The Sony has more HDMI ports, which can be useful if you have multiple devices to connect. Give Feedback

The LG A2 (OLED) is excellent for movies & TV, while the Sony X90J (LCD) is good.
The LG A2, being an OLED TV, offers perfect black uniformity and contrast, which makes for an exceptional movie and cinematic TV experience, especially in dark scenes, and it also has wide viewing angles for consistent colors from different seating positions. On the other hand, the Sony X90J, an LCD TV, provides good contrast and local dimming capabilities but falls short in black uniformity and viewing angles compared to OLED, which could affect the viewing experience in mixed-light conditions and when viewed from an angle.

The LG A2 (OLED) is very good for sports, while the Sony X90J (LCD) is good.
The LG A2 OLED TV provides excellent response time and very good handling of reflections, ensuring clear images during fast-moving sports without distraction from light sources, while its superior viewing angles offer a consistent picture no matter where you're seated. In contrast, the Sony X90J LCD TV, despite its good motion processing, isn't as effective in bright rooms or for viewers sitting off to the side due to its poor reflections handling and narrower viewing angles, and while it has a slightly worse gray uniformity than the LG A2, this difference is generally less noticeable for most content, including sports.

The Sony X90J (LCD) is very good for gaming, while the LG A2 (OLED) is good.
The LG A2, with its OLED screen, provides an excellent response time and very good input lag, which is crucial for gaming, but it's limited by a lower refresh rate of 60Hz and fewer HDMI ports. The Sony X90J may have a slightly lower response time but still very good, and good input lag, combined with a higher refresh rate of 120Hz and more HDMI ports, making it more suitable for high-paced gaming and connecting multiple devices.

The Sony X90J (LCD) and LG A2 (OLED) are both good for bright room, though the Sony X90J (LCD) is somewhat better.
The LG A2 OLED, while offering excellent reflections handling, does not get as bright as the Sony X90J LCD, which has very good SDR and HDR brightness but struggles more with reflections. This means the LG A2 might be suitable for bright rooms if glare isn't a major issue, whereas the Sony X90J can cut through ambient light better but could be more affected by direct reflections.

The LG A2 (OLED) and Sony X90J (LCD) are both very good for cartoons & animation.
The LG A2 OLED provides vibrant colors out of the box and a broad color gamut, making cartoons and animation look lively and true to the creators' intentions. However, the Sony X90J LCD, while offering excellent initial color accuracy, may not provide as wide a range of colors as the OLED, but is brighter in SDR content which makes it more suitable for well-lit rooms when you're watching your favorite animated content.

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."
