Both the Sony A90K and Sony A90J are upper midrange OLED TVs that are similarly priced. The A90K is a 48-inch TV released in 2022, offering excellent picture quality, gaming performance, and sports viewing experience. It struggles somewhat in very bright rooms. The A90J is a slightly larger 55-inch TV with a bit better overall picture quality and performance in bright rooms compared to the A90K. Released in 2021, it also has slightly better sound quality and comes with great speakers. If room brightness is a concern and you'd like better sound, consider the A90J. For a more recent model that's also slightly smaller, the A90K would be a good option. Give Feedback

"In every meaningful department – motion control, contrast, edge definition, detail levels, you name it the A90J puts in a memorably accomplished shift. In fact, the Sony proves outstanding at handling on-screen motion of any and every kind. By the standards of television audio systems, the A90J is a notably punchy and genuinely dynamic performer."
