If you are on a budget and need a TV mainly for viewing in a well-lit room, and you prioritize voice commands for accessibility, the LG UQ7570 may suffice despite its poor performance across picture quality, gaming, and in dark environments. On the flip side, the Sony X90K offers a significantly better viewing experience with good to very good performance in overall picture quality, gaming, sports, movies, and bright room viewing; however, the enhanced experience comes with a higher price. The Sony X90K also has better sound, a higher refresh rate, more HDMI ports, and supports advanced HDR formats like Dolby Vision, which are desirable for a premium experience. If you want a versatile TV that excels with various content and don’t mind paying more, the Sony X90K is a solid choice. 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."
