The LG UP8000 is more budget-friendly and provides adequate performance for diverse content like sports and animation. It has a wider viewing angle, making it suitable for group watching. However, its performance in a dark room is not as strong, which might be noticeable when watching movies. The Sony X90K, although more expensive, offers better picture quality overall, excels in dark room settings, and has superior gaming features with a higher refresh rate. Its brightness capabilities make it a better fit for brightly-lit rooms. Additionally, it supports more advanced HDR formats like Dolby Vision, enhancing the viewing experience for compatible content. If you're a serious gamer or want a TV that performs well in both bright and dark environments and can afford the higher price, the Sony X90K might be the better choice. Give Feedback

"What we liked on this one was the very sharp 4K images it could display, its good up-scaling capabilities, nice viewing angles and extremely low input lag. Lastly the new webOS 6.0 is great even if it needs some time to get your bearings while the redesigned Magic Remote feels fresh even if functionality remains the same."

"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."
