The LG A1 offers superior picture quality for movies and series and provides better performance in dark rooms due to its OLED technology. This TV excels in maintaining black uniformity and viewing angle but is less bright, so it won't perform as well in sunny or very bright rooms. The Sony X90K, on the other hand, is more affordable and better suited for gaming, with its higher refresh rate and lower input lag. It also has better brightness for SDR content which means it will handle well-lit rooms more effectively, but it doesn't quite match the LG A1 when it comes to contrast due to its LCD screen. Both TVs offer good sound quality and support the latest HDR formats. The choice between them depends on whether you prioritize gaming and bright room usage (Sony X90K) or movie watching in darker environments (LG A1). Give Feedback

The LG A1 (OLED) is very good for movies & TV, while the Sony X90K (LCD) is good.
The LG A1 OLED is very good for watching movies and cinematic TV due to its excellent contrast, perfect black uniformity, and good viewing angles, which are crucial for dark room viewing; however its colors may not be as accurate straight out of the box. The Sony X90K LCD, while good for movies and cinematic content, shows weaker black uniformity due to its VA panel and less effective local dimming, but typically displays more accurate colors without initial calibration and retains better brightness for varied content viewing.

The LG A1 (OLED) is very good for sports, while the Sony X90K (LCD) is good.
The LG A1 excels in sports viewing due to its superior response time and broader viewing angles, enhancing fast-paced action and allowing more people to watch comfortably from different spots in the room. The Sony X90K, while also good for sports, offers better motion processing but doesn't match the LG A1 in reflection handling, and viewing angles, which may make it less ideal in well-lit environments or for larger groups.

The Sony X90K (LCD) is very good for gaming, while the LG A1 (OLED) is good.
The LG A1 offers superior input lag performance, which is critical for a responsive gaming experience, but it has a lower refresh rate than the Sony X90K. On the other hand, the Sony X90K provides a higher refresh rate, which is great for fast-paced games, and very good response time, leading to minimal motion blur.

The Sony X90K (LCD) is very good for bright room, while the LG A1 (OLED) is only fair.
The Sony X90K has higher brightness in both standard and high dynamic range content, which, combined with its superior reflections handling, makes it more suitable for bright rooms than the LG A1. The LG A1, being an OLED, offers perfect contrast and a wider color volume and gamut which can enhance picture quality in darker environments; however, its fair brightness and reflection handling can be limiting in well-lit spaces.

The LG A1 OLED TV excels in upscaling lower-resolution content and offers a wide viewing angle, making it suitable for news, talk shows, and general TV watching where viewers may be seated at different positions.

Al Griffin | December 2022
"As Sony’s next-to-flagship LCD TV, the X90K series delivers impressive performance for the price. The XR90K had fairly accurate out-of-box color. The TV’s multi-position stand lets you either set the screen flush with any stand its mounted on or elevate it to clear space for a soundbar. With the latter option, you get around 3 inches of clearance enough to accommodate most soundbars. The X90K’s excellent suite of gaming features ranks it up there with the best 120 Hz 4K TVs."
