Hisense U8K 65" (Mini-LED ULED) vs Sony X90K 65" (Full Array LED)
The Verdict
Both 65-inch 4K TVs deliver excellent value at $1,099, but each excels in different areas. Hisense U8K leverages Mini-LED technology with 2,000 nits peak brightness, 144Hz refresh rate, and superior 40W audio with 2.1ch configuration,ideal for gaming and bright room viewing. Its Wi-Fi 6E and 6ms input lag make it more responsive. Sony X90K counters with superior contrast control through Full Array LED dimming and refined color accuracy, historically Sony's strength in the mid-premium segment. It supports HDR10+ versus Sony's omission, though Sony's processing typically elevates content quality. Gaming performance favors Hisense slightly (8ms vs 6ms input lag, 144Hz vs 120Hz). For gaming enthusiasts and brightness-dependent environments, Hisense edges ahead. For cinephiles prioritizing contrast and color fidelity, Sony remains compelling. Your preference depends on priorities: raw gaming performance and brightness (Hisense) or contrast quality and color science (Sony).
