If you prefer superior picture quality, especially in dark rooms, and are willing to pay more, the LG C1 OLED might be suitable. However, if you're looking for a more affordable TV that performs well in both bright and dark environments, the Sony X90K LCD could be a better choice. The Sony is less expensive but won't offer the same level of picture quality as the LG, particularly with black levels and wide viewing angles. Give Feedback

The LG C1 (OLED) is very good for movies & TV, while the Sony X90K (LCD) is good.
The LG C1's OLED technology provides perfect blacks due to an infinite contrast ratio and excellent black uniformity, enhancing movie and cinematic TV watching especially in dark scenes, and its wide viewing angles ensure a consistent image when viewed from the side. In contrast, the Sony X90K offers good contrast and black uniformity with its LCD screen, but it falls short compared to OLED, and its narrower viewing angles mean the image might degrade when seen from an angle, though its local dimming helps improve overall picture quality.

The Sony X90K (LCD) is very good for bright room, while the LG C1 (OLED) is good.
The Sony X90K provides better SDR and HDR brightness levels than the LG C1, making it more suitable for viewing in bright rooms; however, the LG C1 handles reflections more effectively, which can make it a better choice if glare is a concern. The Sony X90K with its higher brightness capability will outperform in particularly bright environments, while the LG C1 will still deliver stronger contrast and more vibrant colors thanks to its OLED technology.

The LG C1 (OLED) and Sony X90K (LCD) are both very good for cartoons & animation.
The LG C1 delivers vibrant and accurate colors straight out of the box, with an OLED panel providing a very wide color gamut, making it an excellent choice for watching cartoons and animation. The Sony X90K also provides good colors out of the box and a good color gamut, but it may fall behind the LG C1 in terms of color volume and contrast due to its LCD screen, which is still a strong option for animated content albeit with slightly less color richness.

The Sony X90K (LCD) and LG C1 (OLED) are both very good for news, talk, & other TV.
The LG C1 stands out for its superior upscaling abilities, making lower resolution content from news and television programs appear crisper, and it offers exceptional contrast with perfect blacks due to its OLED technology, but has only good SDR brightness which may not be the best for very bright rooms. On the other hand, the Sony X90K provides very good SDR brightness, ensuring clear visibility even in well-lit environments, and better upscaling compared to other LCD models, with somewhat lesser contrast quality due to local dimming capabilities that don't match OLED.

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."
