The LG B1 uses OLED technology, which delivers superior picture quality, especially in darker environments, making it ideal for watching movies. OLED TVs also have better viewing angles and are better for gaming due to their faster response times. However, the LG B1 is significantly more expensive. On the other hand, the Sony X90K, while using LCD technology, still offers good performance for mixed usage like TV shows, sports, and gaming and does better in bright rooms compared to OLEDs, all at a lower cost. If budget permits and you prioritize cinematic experiences and gaming, the LG B1 is an excellent choice. But if you're looking for better value, particularly in well-lit spaces, and can compromise slightly on picture quality, the Sony X90K is a compelling alternative. Give Feedback

Techradar

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."
