Hisense U8K 65" (Mini-LED ULED) vs Samsung S90C 65" (4K OLED)
The Verdict
Both 65-inch models deliver premium gaming performance with 6ms input lag, VRR, and ALLM support, but serve different priorities. Hisense U8K leverages Mini-LED technology with exceptional peak brightness (2000 nits), superior for bright rooms and HDR gaming, plus Wi-Fi 6E connectivity and a 144Hz native refresh rate at $1099. Samsung S90C employs QD-OLED technology delivering infinite contrast ratios, perfect blacks, and superior color accuracy at 1500 nits brightness,ideal for dark room viewing and cinematic content. Samsung's thinner design (0.5" vs 2.7") and Tizen OS with broader smart features add refinement. Connectivity-wise, Hisense edges ahead with Wi-Fi 6E. Audio specs match identically at 2.1ch/40W with Dolby Atmos. For value-conscious buyers prioritizing brightness and gaming specifications, Hisense U8K excels. However, those willing to invest the additional $900 for superior contrast, OLED color performance, and design elegance should choose Samsung S90C.
