The Sony X80J 55-Inch 4K Ultra HD LED TV. And the Samsung 75" QN90B Neo QLED 4K TV represent two distinct approaches to mid-range 4K panels, one built around traditional LED backlighting with solid color accuracy. And the other around Mini-LED zones paired with quantum dots for higher contrast and wider viewing angles. Public reviews consistently note the Sony X80J’s reliable motion handling. And straightforward Google TV interface, while the Samsung 75" QN90B Neo QLED 4K TV draws attention for its 120 Hz native refresh rate, expanded gaming features. And noticeably larger 75-inch canvas that fills more of a living room. Neither manufacturer has released final figures on peak brightness, exact HDMI 2.1 port counts, or full VRR and ALLM support, leaving some performance questions open until independent measurements appear. The short version: the Samsung 75" QN90B Neo QLED 4K TV suits buyers who prioritize screen size, refresh rate. And an extensive feature list over the more modest but still capable Sony X80J.

Verdict: The X80J 55-Inch 4K Ultra HD LED TV offers lower starting price ($699.99 vs $2,399); the Samsung 75" QN90B Neo QLED 4K TV counters with more refresh rate (120Hz vs 60Hz). Neither publishes peak brightness, HDMI 2.1 ports or VRR / ALLM yet.

Sony X80J 55-Inch 4K Ultra HD LED TV: 5.5/10
