If you mostly watch movies in a dark environment and prioritize picture quality with deep blacks and vibrant colors, the Sony A90K OLED, with its superior dark room performance and overall picture quality, is a great choice. However, it might not be as impressive in a very bright room due to fair brightness. On the other hand, the Sony X90K LCD has very good brightness and performs better in bright rooms, and while it is also great for movies and sports, its dark room and viewing angle performance is not as strong as the OLED. The LCD is also often significantly less expensive, making it a more cost-effective option while still delivering a very good overall viewing experience. Give Feedback

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."
